Scrum Questions

Scrum is not a simple thing. Many people ask me questions on different Scrum topics. I will publish my answers here.

Please, do not post questions with answer options. I got several complaints about copyright violations. Just ask the question in your own words.
1. Essential features of a Scrum Team
Q: It is regarding the question on psm-quiz on your site.
What are the two essential features a Scrum Team should possess?

  1. It should choose how best to accomplish their work, rather than being directed by others outside the team
  2. It should have all competencies needed to accomplish the work without depending on others not part of the team
  3. It should use tools, processes and techniques approved by the Organization
  4. It should be flexible enough to complete all the work planned for the Sprint even if some team members are on vacation

Though the explanation mentions 1 &2 as the answer for this but shouldn’t option 3 also be the answer for this question. Development team should be using tools, process and techniques approved by organization and if there is any hindrance the scrum master should notice this as impediment and talk to respective stakeholders?

Mikhail: For me #3 looks like a contradiction to #1. As long as the team creates increments according to the DoD, it can use any techniques, tools, etc.

2. Architecture type questions
Q: I noticed that the official Scaled Scrum open exam contains a few architecture type questions. There does not seem to be any reference material around this subject area and just wondered if you could point out some good learning material?

Mikhail: I think, Scaled Scrum does not prescribe any particular architecture. It only says the dependencies between teams should be minimized and we should inspect and adapt frequently. So, it is an ongoing process. Evaluating the current architecture and suggesting ways to improve it is a part of every Sprint.

As I remember, the open Scaled Scrum quiz contains only the following topics:

Q: A system is decomposed into elements like workflows, features, capabilities, etc. How it affects Scrum Teams on a scaled project?
A: It will be reflected in the implementation.

Q: Two ways how Dev Teams can ensure a good application architecture?
* Architecture is an ongoing discussion
* The DT should have a set of architecture principles and follow them

Q: How to start a big complex project?
A: Form 1-2 teams of best developers for implementing the core, add more teams later.

You see, there are no any specific architectural questions. So, nothing to read about this. 🙂
However, the exam contains references to SOA (service-oriented architecture). It is worth to get a high level view of SOA, or at least read its definition. For example at Wikipedia: https://en.wikipedia.org/wiki/Service-oriented_architecture

3. Opportunities to inspect and adapt
Q: Your quiz contains a question that asks to check all the opportunities to inspect and adapt from a list. There is “Sprint” option. Why it is considered as incorrect?

Mikhail: The idea is simple. Sprint is a special event that is nothing more than a time-box for other events. The Scrum Guide explains it in this way: “Other than the Sprint itself, which is a container for all other events, each event in Scrum is a formal opportunity to inspect and adapt something.”

4. Who creates DoD?
Q: Your quiz has the following question: Who is responsible for creation of the Definition of “Done”? The expected answer is the Development Team. However, some Scrum materials declare that the Scrum Team creates DoD. What is the correct answer?

Mikhail: The Scrum Guide says: “The Development Team of the Scrum Team must define a definition of “done” appropriate for the product.” So, the correct answer is the Development Team.
From my point of view, DT owns DoD on behalf of the whole Scrum Team. So, it is possible to say “Scrum Team creates DoD”, however “Development Team creates DoD” is more precise.

5. Stakeholders and PB transparency
Q: During sprint review stakeholders notice that the product development progress is not very clearly visible and lacked transparency. Moreover, they are not able to understand the next steps. Who is responsible for this?

Mikhail: The Product Owner is responsible for this.

In the Scrum Guide you can find that the PO is responsible for:
* Ensuring that the Product Backlog is visible, transparent, and clear to all, and shows what the Scrum Team will work on next;

At the Sprint Review:
* The PO explains what Product Backlog items have been “Done” and what has not been “Done”;
* The entire group collaborates on what to do next, so that the Sprint Review provides valuable input to subsequent Sprint Planning;

The Product Owner is the Lead Facilitator of Key Stakeholder Involvement. The PO is responsible for identifying the key stakeholders for the product and involving them as necessary throughout the development effort.

6. UI markup to better understand a Product feature?
Q: Scrum Team decides they need to create one more artifact UI markup to better understand the product feature, can they proceed or not since Scrum Teams should capture product features/needs only in Product Backlog?

Mikhail: Of course, the team can proceed. Right, PB is the single source of requirements for any changes to be made to the product. If the Scrum Team does not understand what should be done next, it means the PB needs to be refined. The Product Owner should put his product vision as backlog items, maybe with help of the Development Team.
A product backlog item should contain everything necessary to be understood by any member of the Scrum Team. So, if a new UI markup needs to be developed, it should be a part (task) of some item (story) in the PB. When the markup is ready, it should be attached to the item.
So, the answer is not a simple “yes/no”. I would carefully look at the wording of the suggested answers to be maximally close to the point I described above.

7. Stakeholders at PBL refinement sessions?
Q: Can the PO invite stakeholders to PBL refinement sessions?

Mikhail: I would say the PO should not usually do this. The PO must be the arbiter of product value and how it is represented to the team. Frequently key stakeholders do not know exactly what they want and how it can be achieved. This is a job for the PO to understand their needs, decide how they can be fulfilled with the maximum value.
Probably, in rare cases a key stakeholder can be invited as a domain expert to a product refinement session. However, the PO should have the final word.

8. Does PB contain only functional requirements?
Q: Does the Product Backlog contain only functional requirements for the Product?

Mikhail: No. The Scrum Glossary gives the following definition for Product Backlog: “It is an ordered list of the work to be done in order to create, maintain and sustain a product.” So, Scrum is not specific about exactly what a Product Backlog Item is or how it should be expressed. It is just “work to be done”.
The Scrum Guide gives a bit more details about a PBI: it should have the attributes of a description, order, estimate, and value. However, it does not change the “work to be done” definition much. For example, a Product Backlog can contain knowledge acquisition tasks, prototyping, technical chores etc.
However, there is one important moment: a Product Backlog should contain items that the Product Owner cares about, in the sense that they add clear business value and can be ordered by him or her. If there are some “Developer Stories”, i.e. removing technical debt, they can be introduced by the Development Team into their own Sprint Backlog, if they think such stories are necessary in order to help mitigate a technical risk.

9. Should the PO approve the DoD?
Q: Should the PO approve the DoD?

Mikhail: The following points should be taken into the account:
1. The Development Team is responsible for the Definition of Done.
2. There is no direct requirement in the Scrum Guide for a formal approval of the DoD by the PO.
3. The PO as a member of the Scrum Team participates in the Sprint Retrospective where the DoD is revised and adapted.

‘No’ answer is more comfortable for the question. However, the PO can affect the DoD at the Sprint Retrospective by making suggestions for the Dev Team how to improve it. Also the PO can bring some non-functional requirements for the product and the Dev Team usually applies them via DoD. See 11. How to address non-functional requirements? and 46. Non-functional requirements, PO and DoD

10. Can the SM create a PBI?
Q: Who can create a Product Backlog item? Can the Scrum Master do it?

Mikhail: The Scrum guide says:
The Product Owner is the sole person responsible for managing the Product Backlog… The Product Owner may do the above work, or have the Development Team do it. However, the Product Owner remains accountable.

Creation of a PBI relates to PB management. So, certainly the PO is responsible for this. However, he can delegate this work to the Development Team.
If the Scrum Master combines his role with the Developer role (the most common situation), he is a part of the Development Team and can create PBIs when it is agreed with the PO. Otherwise, I think, he should not do it.

In my quizzes I have a similar question: who can change the PB? The answer is “The PO and the DT with permission of the PO.”

11. How to address non-functional requirements?
Q: How to address non-functional requirements such as security, performance?

Mikhail: Non-functional requirements describe qualities of the system being developed. E.g. the system should be secure, extensible and have acceptable performance. The only way to meet such requirements is to have them as a part of the DoD and check every Increment against these criteria.
From my side I would mention that if some non-functional requirements relate only to a part of the Product (i.e. to some feature), most likely the requirements should be processed as a sub-task within this feature instead of the DoD.

12. How does DoD help in Sprint Planning?
Q: How does DoD guide the DT in knowing how many PBL items it can select during Sprint planning?

Mikhail: The DoD helps to reveal the work necessary to complete a PB item. So, it helps to estimate how much time it will take. With better estimations the Development Team can better plan which items can be completed in the upcoming Sprint.

13. When the Sprint length is determined?
Q: When the Sprint length is determined and who decides on it?

Mikhail: The whole Scrum Team should come to a solution about the first Sprint length before starting it. The length of the following Sprints can be changed (adapted).
There is no a formal event for this purpose. The Scrum Guide limits only the maximum length by one month. However, the following points can be taken into account:

  • The pace at which the PO wants to have increments (new features implemented), demonstrate them to the Key Stakeholders and get feedback.
  • Experience of the SM. What was the optimal length for teams doing a similar work.
  • Experience of the DT. Too long Sprints make planning difficult. Too short Sprints do not allow to implement bigger features in one chunk, but give faster feedback.

From my experience, the optimal Spring length is 2 weeks.

14. What is enough to start a first Sprint?
Q: What is enough to start a first Sprint?

Mikhail: A first Sprint requires no more than a Product Owner, a team, and enough ideas to potentially complete a full Sprint.

15. Concerns about progress and budget
Q: A Project Manager working with your Scrum Team has raised concerns about progress and money spent. What are the two best responses?

Mikhail: First of all, there is no Project Manager role in Scrum. So, the manager from the question is an external person for the team.

My best options are below:
a. Invite the manager to the next Sprint Review. There the manager will see what was completed in the Sprint, what is the feedback from the Key Stakeholders, what are the priorities for the next Sprint, get some review of the timeline and budget.
b. In agile practices the duty of all participants is to be transparent. Those who need information are responsible for getting it. They have a duty to ensure that the information they act on is obtained in a timely fashion and with minimal filtering.
So, the manager can investigate the artifacts of the Scrum Team: the Product Backlog, the Sprint Backlog, the Increment. The team is responsible for sharing these artifacts and any information radiators that can help to make the artifacts more transparent (e.g. burn down charts, story boards, etc.)

One more point is that proper use of Scrum makes sure that the most valuable features are implemented first and the proof of success lies in ongoing delivery and not in reporting.

Update: I got the suggested options for the question:
1) Scrum doesn’t have PMs
2) Share the PB and forecast for the sprint
3) Share the current roadblocks
4) Share the last stakeholder report by PO

I see the options fit well with my answer:

1) Scrum doesn’t have PMs
* Correct
2) Share the PB and forecast for the sprint
* Correct. Scrum Team artifacts should be transparent.
3) Share the current roadblocks
* Wrong. Sharing artifacts is much better.
4) Share the last stakeholder report by PO
* Wrong. The PO does not have duty to prepare a special report for the Key Stakeholders.

16. Individuals to consult with for PO to maximize value
Q: Who are the individuals the PO should consult with when considering the value of a Product?

Mikhail: The most important individuals for maximizing value for the Product are the Key Stakeholders. The PO should identify and involve them as necessary throughout the development effort. The Key Stakeholders are typically customers, purchasers, users, and the people that fund the product’s development. These people may be internal or external to the Organization.

17. Which work can PO delegate?
Q: What is Product Owner work that a Product Owner might delegate? Choose one from (a. Facilitating Stakeholder Involvement, b. Writing Product Backlog Items, c. Facilitating meetings).

Mikhail: The PO can delegate writing Product Backlog Items.

The Scrum Guide contains:

The Product Owner is the sole person responsible for managing the Product Backlog. Product Backlog management includes:

* Clearly expressing Product Backlog items;

The Product Owner may do the above work, or have the Development Team do it.

The PO is responsible for identifying the Key Stakeholders and involving them as necessary.

The Scrum Master is responsible for facilitating the Scrum events.

18. Three things to focus on for the PO?
Q: What three things might a Scrum Product Owner focus on to ensure his product delivers value?

Mikhail: There are several possible good answers. I would suggest the PO should focus on:
* Key Stakeholder Involvement
In order to maximize value, the PO should identify the key stakeholders for the product, and involve them as necessary throughout the development effort.
* Product Marketplace
The Product Owner should be expertly aware of the marketplace for the product. They should constantly be gathering and re-gathering information and data regarding the marketplace, so that the product value is maximized.
* Product Release Decisions
The PO is the one and only person who can decide whether to release the latest increment of the Product. In order for value to actually be captured, a release of the product must occur.

19. Must the PO write all PBIs?
Q: Must the Product Owner write all of the Product Backlog items (e.g. user stories, non-functional requirements, etc.) on the Product Backlog before handing them over to the Development Team?

Mikhail: Of course not. This question is very similar to the question #17 above.
Who does the work of updating and managing the Product Backlog is a collaboration between the Product Owner and the Development Team. However, the Product Owner is solely responsible and accountable for the decisions in the Product Backlog.
For example, the PO can write nothing, but explain everything in detail to the Development Team. Then the team will create the required PB items and write down all the details.

20. PO responsibilities
Q: My job as a Product Owner focuses on the following (Choose 2 answers):

  • A. Writing clear, transparent User Stories
  • B. Working with customers and stakeholders to identify the most important product requirements
  • C. Being with the Scrum team all the time, just in case they need me to clarify a requirement
  • D. Clearly communicating project or release status and strategies to customers and stakeholders

Mikhail:

  • C is wrong because the PO does not have to spend all the time with the DT. The PO has other things to do. For example, communicating with Key Stakeholders. The main PO commitment is product value delivery. So, he or she should spend enough time (but not all the time) with the DT to meet that commitment.
  • A is just partially right. Writing clear user stories is important, but the Product Backlog also contains many other things like features, functions, requirements, enhancements, etc. The PO is responsible for the whole management of the Product Backlog. Also the PO can ask the DT to write the stories.
  • D is partially correct because the PO should communicate his product vision not only to the Key Stakeholders, but also to the Scrum Team.
  • B is correct. Identifying the most valuable Product features one of the most important PO responsibilities.
  • So, I would answer B and D.
21. All DT work originates from PB
Q: All work to be done by the Development Team must ultimately originate from the Product Backlog?

Mikhail:
I think, in the broad sense the answer is “yes”. The PB is the source for the Sprint Backlog. The Sprint Backlog is the source of the Dev Team work. However, only the Dev Team knows how to implement Sprint Backlog Items. It can involve technical tasks, for example, removing some technical debt or even installing a development environment for a new developer.

22. How does SM help DT and PO in communication?
Q: Which technique is the best way the Scrum Master can ensure that the Development Team communicates effectively with the product owner?

Mikhail:
The Scrum Guide says: the SM helps the PO to understand and practice agility. Agility means using the most effective ways to collaborate. Direct collaboration between the PO and the DT is the most effective one. So, the best technique for SM is to monitor communications between the DT and the PO and facilitate direct collaboration.

23. Can the PO measure success by team velocity?
Q: A Product Owner can measure success by an increase in the team’s velocity?

Mikhail:
No. It is just one of the first steps to success. Success in Scrum is getting maximum value with the existing resources. Value, as defined in a Scrum context, is the financial (or social) benefit an organization receives or might receive by creating and releasing the product under development. In order for value to actually be captured, a release of the product must occur. The sooner you release, the sooner you can start capturing the value created by the product.
Increase in team’s velocity shows that the Dev Team became more mature and can do more in the same time frame.

24. Who are the participants of Sprint Review?
Q: The Sprint Review is mainly an inspect and adapt opportunity for which group?

Mikhail:
The Scrum Guide says: During the Sprint Review, the Scrum Team and stakeholders collaborate about what was done in the Sprint.
So, the answer is “the Scrum Team and stakeholders”.

25. New DTs and productivity
Q: If two Scrum Teams are added to the development of a product that previously only had one Scrum Team, what will be the immediate impact on productivity of the original Scrum Team?
A) Its productivity is likely to stay the same
B) Its productivity is likely to increase
C) Its productivity is likely to decrease

Mikhail: C.
In a short term the productivity will decrease because the new teams will spend time to get up to speed with the Product. The old team will spend a lot of time for communications with the new teams.

26. Factors affecting the Sprint length
Q: What three factors are best considered when establishing the sprint length? Choose 3 answers.
A) The frequency at which team formation can be changed
B) The organization has mandated similar length sprints
C) The risk of being disconnected from the stakeholders
D) The level of uncertainty over the technology to be used
E) The ability to go to market with a product release.

Mikhail: C, D, E.
A. is wrong because Development Teams in Scrum are self-organizing and can decide to change at any time.
B. is bad because Organization is not responsible for the Sprint length. It is determined by the Scrum Team. The PO and the Dev Team should agree on this. The SM may have some coaching duties to perform in that regard.
C. is good because the bigger part of interaction with the Key Stakeholders happens at the Sprint Review meeting. If the Sprint length is bigger, this feedback loop becomes longer.
D. Shorter Sprints is an effective way to hone in on the requirements or try out the technology before committing to a solution.
E. Shorter Sprints suppose that the Dev Team produces “done” increments more frequently. It allows the PO to release the increments more frequently too.

27. How to divide 100 developers?
Q: How would an organization with 100 developers divide into teams?
A) Manger would divide them depending on location, bonding between members and xyz…
B) Developers will form teams themselves.
C) Scrum master will assign them according to budget.
D) Understanding scrum encourage self organization, developers will organize themselves into teams based on skills.
E) Product owner brings all developer working on same product together for planning and depending on functionalities , developer with self organize themselves into teams.

Mikhail: All the options related to self-organization are correct: B, D and E.

28. When the Sprint Goal is crafted?
Q:The Sprint Goal is the result of the Sprint Planning, just as the Sprint backlog. True or False?

Mikhail: Of course the answer is “True”. The PO comes to the Sprint Planning with an idea for the Sprint Goal and then all the Scrum Team crafts the final version of the Goal.

29. Sprint Review topics?
Q: Which topics should be discussed in the Sprint Review?
A) The scrum process and how it was used during the Sprint
B) Coding and Engineering practices
C) Sprint Results
D) All of the above

Mikhail: The Scrum Guide says “A Sprint Review is held at the end of the Sprint to inspect the Increment and adapt the Product Backlog if needed.”
So, D. option would be great for the Sprint Retrospective meeting, but it is wrong for this question. All the topics related to the development process are discussed at the Sprint Retrospective.
So, the correct answer for this question is C. Sprint Results.

30. Participate vs Attend
Q: I noticed an error in your questions. It looks like there are two similar questions with different answers:

  1. In which meetings the Key Stakeholders are allowed to participate? The correct answer is “The Sprint Review”. The Sprint Planning was evaluated as wrong in this question.
  2. Select the two meetings in which people outside the Scrum Team are allowed to participate. The correct answers are “The Sprint Planning” and “The Sprint Review.”

The Key Stakeholders are people outside of the Scrum Team, so in the second question they are allowed to participate in the Sprint Planning, in the question #1 they are not. Is there an error in one of the questions?

Mikhail: The difference between “participate” (come to the meeting and speak) and “attend” (come to the meeting, but not speak) is a bit difficult. However, the real exam uses it for sure.

The question #1 is correct. The Sprint Review is the only formal Scrum event where the Key Stakeholders are allowed to take part in. They are invited by the Product Owner and actively give their feedback on the Product.

The question #2 is also correct. It looks like your confusion comes from mixing together concepts of “Key Stakeholders” and “technical experts”. The Key Stakeholders are typically customers, purchasers, users, and the people that fund the product’s development.

In “Sprint Planning” chapter the Scrum Guide says: “The Development Team may also invite other people to attend to provide technical or domain advice.” So, these people are not the Key Stakeholders. They are technical and domain experts. And these people give technical advice. It obviously means they can speak at the meeting. Using the word “attend” here looks like a little inconsistency between the Scrum Guide and the questions.

I hope, now you see the Key Stakeholders go to the Sprint Review and technical domain experts could go to the Sprint Planning. So, there are two meetings when people outside of the Scrum Team can come and speak.

31. Characteristics of a valuable Increment?
Q: In which cases an Increment is valuable? (choose 2 answers)
A) It reduces long-term operational costs
B) It increases customer satisfaction
C) It is delivered on time
D) It has all the features that the Product Owner expected

Mikhail: The answers are A and B.
If you take a look at the Evidence Management Guide, you will find A and B among the Key Value Measures in Current Value section. C and D are absent in this list.

32. Product Backlog is...
Q: A Product Backlog is (choose 3):
A) Managed by the Product Owner.
B) Ordered based on priority, value, dependencies, and risk.
C) An inventory of things to be done for the Product.
D) An exhaustive list of upfront approved requirements to be implemented for the system.
E) Only visible to the Product Owner and stakeholders.

Mikhail: I would choose A, B and C.
E is wrong because all the Scrum Team members can see the Product Backlog.
C and D answers are similar. I like C better because a Product Backlog is never complete, so it cannot be exhaustive. From the other side, if a requirement is in the Product Backlog, it is approved by the PO. So, “an exhaustive list of upfront approved requirements” could be also valid. I do not like this question much because of the ambiguous wording.

33. Metrics for value delivery?
Q: Which two (2) metrics will help a Product Owner establish that value is being delivered?
A) Customer satisfaction
B) Velocity
C) Time to market
D) Budget spent
E) Productivity

Mikhail: A and C are correct. If you take a look inside the EBM guide, you will find “Customer Satisfaction” KVM and “Time to Market” KVA. Budget, velocity and productivity do not contribute directly to capturing Product value.

34. What is Sprint Backlog?
Q: Which statement best describes the Sprint Backlog as outcome of the Sprint Planning?
A) Each task is estimated in hours.
B) It is a complete list of all work to be done in a Sprint.
C) Every item has a designated owner.
D) It is the Development Team’s plan for the Sprint.
E) It is ordered by the Product Owner.

Mikhail: The Scrum Guide contains
“The Sprint Backlog is the set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal.”
“The Development Team modifies the Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint. This emergence occurs as the Development Team works through the plan and learns more about the work needed to achieve the Sprint Goal.”

A) Wrong because there is no requirement to have estimation in hours
B) Wrong because the team cannot foresee all the work in the beginning of a Sprint
C) Scrum does not require a designated owner for items
D) The best option here
E) Wrong because the Dev Team owns the Sprint Backlog

35. Cross-functional team?
Q: What does it mean for a Development Team to be cross-functional?
A) Developers on the Development Team work closely with business analysts, architects, developers and testers who are not on the team.
B) The Development Team is a virtual team drawing from separate team of business analysts, architects, developers and testers.
C) The Development Team includes not only developers but also business analysts, architects,developers and testers.
D) The Development Team includes cross-skilled individuals who are able to contribute to do what is necessary to deliver an increment of software.

Mikhail: The best option is D. Scrum recognizes just one role “Developer” within the Development Team. The Scrum Guide tells:
– Development Teams are cross-functional, with all the skills as a team necessary to create a product Increment;
– Scrum recognizes no titles for Development Team members, regardless of the work being performed by the person;
– Individual Development Team members may have specialized skills and areas of focus, but accountability belongs to the Development Team as a whole.

36. Scrum value affected by lack of trust
Q: Which Scrum value is affected by lack of trust in the Scrum team?

Mikhail: The Scrum Guide says: “When the values of commitment, courage, focus, openness and respect are embodied and lived by the Scrum Team, the Scrum pillars of transparency, inspection, and adaptation come to life and build trust for everyone.”
So, the answer will be: commitment, courage, focus, openness and respect.

37. Which Scrum values are exhibited?
Q: Which Scrum values are exhibited by not building product backlog items that have low business value?

Mikhail: The same as in question #36, the answer will include some of these: commitment, courage, focus, openness and respect. For me the most suitable answer looks like focus (focusing on the most important things) and openness (the PB items and their values are transparent to everyone).

38. The same Sprint length for all teams
Q: There is the following question in your quiz: All the Scrum Teams working on the same Product should have the same Sprint length and the expected answer is “False”.
I would disagree because the Teams must do integrated increment in the end of the Sprint. It means Sprint length of all the Teams must be the same.

Mikhail: The Scrum framework does not require the same Sprint length or aligned Sprints for all teams. The Nexus framework is built on top of the Scrum and also has no requirements regarding this.

However, if several teams work together using the Nexus Framework, they work in the same Nexus Sprint, have common Nexus Sprint Planning and other events. You are right, the teams should use (but do not have to) the same Sprint length and all Sprints should start and finish together to avoid inefficiency.

Usually the emphasis is placed on having a shared Definition of Done. Another option could be when one team has 2 week sprint length, whereas another teams use 4 weeks.

One of the best things about Nexus – it is less prescriptive when compared to SAFe & LeSS. Usually there are many ways to solve the inefficiencies. But definitely not by making something prescriptive.

39. Communications between the DT and Stakeholders
Q: In my opinion the stakeholders should never initiate communications during the sprint however I do think under the proper conditions that the development team should have access to the stakeholders for clarifications during the sprint. Is this an anti scrum pattern? I am not a big fan of gong up and down ladders for communications such has the product owner having to be an tweener.

Mikhail: The PO is the lead facilitator of Key Stakeholder involvement. The PO should involve them as necessary throughout the development effort. The PO is responsible for making sure that the Key Stakeholders attend and interact in the Sprint Reviews, but really the Stakeholders can be involved with the Scrum Team any time where it’s valuable to have the stakeholder input.
Product ownership is not a committee. The PO is responsible for the product value and how it is represented to the team. So, in the case of any contradiction, the issue must be explained to the PO as soon as possible. Then the PO will communicate with the Stakeholders, resolve it and communicate solution back to the team.
It is an anti-pattern if someone does the PO work for the Dev Team.

40. Product Backlog size
Q: I have seen articles stating the backlog should not grow excessively large. Never above a hundred or so items. Here I do not agree. I believe once a piece of information that has value is identified that it should be added to the backlog even if the item will not be worked on in the near future. I do agree that you would never have many items in the backlog that are groomed to the level to being sprint ready. What is the consensus of backlog size in Scrum.

Mikhail: I completely agree that any valuable idea how to make the product better should be added to the backlog. However, only the top items for one or two next Sprints should be refined enough (be in “ready” state).
With bigger backlogs it becomes harder to order the items and find dependencies. However, there are helping techniques. For example, the stories could be grouped into epics.

41. Why is the Increment the sum of all previous Increments?
Q: I am a bit confused by this definition: “The Increment is the sum of all the Product Backlog items completed during the Sprint and the value of the increments of all previous Sprints.” Can you elaborate?

Mikhail: It is because of two reasons:
1. All the previous work is required for the Increment done in this Sprint to have value and to be potentially releasable
2. An Increment must be tested adequately. This includes regression testing.

42. What is the result of the Sprint Review?
Q: Why the answer to “What is the result of the Sprint Review?” is ” A revised Product Backlog that defines the probable Product Backlog items for the next Sprint” and not “Common understanding of progress toward the Sprint Goal and how progress is trending toward completing the work in the Sprint Backlog”?

Mikhail: First of all, the Scrum Guide tells: “The result of the Sprint Review is a revised Product Backlog that defines the probable Product Backlog items for the next Sprint. The Product Backlog may also be adjusted overall to meet new opportunities.”

The second option relates to the Daily Scrum: “The Development Team uses the Daily Scrum to inspect progress toward the Sprint Goal and to inspect how progress is trending toward completing the work in the Sprint Backlog.”

I agree, at the Sprint Review the PO explains what Product Backlog items have been “Done” and what has not been “Done”. However, what is more important, the whole group collaborates on what to do next, so that the Sprint Review provides valuable input to subsequent Sprint Planning.

43. What belongs solely to the DT?
Q: I have a question regarding two questions in the PSM I quiz at your website:
1. Who is responsible for creation of ‘Definition of Done’?
– Answer is mentioned as ‘Development Team’
2. What belongs solely to the Development Team?
– Answer is only “The Sprint Backlog” and it didn’t include ‘Definition of Done’

If the answer for #1 is Development Team, the answer for #2 should also include “Definition of Done” as per my understanding. Can you please throw some light on the answers to these questions?

Mikhail: The Scrum Guide contains: “Only the Development Team can change its Sprint Backlog during a Sprint. The Sprint Backlog is a highly visible, real-time picture of the work that the Development Team plans to accomplish during the Sprint, and it belongs solely to the Development Team.”
and
“the Development Team of the Scrum Team must define a definition of “Done” appropriate for the product.”, “This is the definition of “Done” for the Scrum Team and is used to assess when work is complete on the product Increment.”
So, the DoD is for the whole Scrum Team. However, the DT is responsible for it (on behalf of the Scrum Team).
There is no any contradiction.

44. Does PO change Sprint Backlog?
Q: The Product Owner has the authority to replace an item in the Sprint Backlog. True or false?

Mikhail: The Scrum Guide contains: “Only the Development Team can change its Sprint Backlog during a Sprint.
So, the answer is “False”.

45. Is Sprint Backlog frozen after Sprint Planning?
Q: Is the Sprint Backlog frozen after the Sprint Planning?

Mikhail: The Scrum Guide clarifies it: “The Development Team modifies the Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint. This emergence occurs as the Development Team works through the plan and learns more about the work needed to achieve the Sprint Goal.
As new work is required, the Development Team adds it to the Sprint Backlog. As work is performed or completed, the estimated remaining work is updated. When elements of the plan are deemed unnecessary, they are removed.

So, the answer is “No”, not frozen.

46. Non-functional requirements, PO and DoD
Q: It looks like two of your questions have a contradiction in the answers:
Q1: The Product Owner wants to apply some non-functional requirements to the Product. What is the best way to proceed?
A1: Add the non-functional requirements to the DoD and check every Increment against these criteria
Q2: Who is responsible for creation of the Definition of “Done”?
A2: The Development Team

Mikhail: It looks like your confusion is like this:
The Product Owner wants to apply some non-functional requirements… The best way is to add the non-functional requirements to the DoD… The Dev Team is responsible for the DoD. How the PO can add the requirements into the DoD?

Well, there is no any contradiction.
Non-functional requirements describe qualities of the system being developed. E.g. the system should be secure, extensible and have acceptable performance.
The PO explains the requirements to the Dev Team. The team has two options how to handle these requirements:
1. Add a new sub-task for every Product Backlog Item to make sure the non-functional requirements are met for this particular item (feature)
2. Add the non-functional requirements to the DoD. So, every Increment will be validated against these requirements.

The second way looks more robust because having the requirements as part of the DoD won’t allow the team to forget about them when working on new items. It also will increase transparency.

So, the PO does not change the DoD. He asks the Dev Team to produce Increments that meet the non-functional requirements. The Dev Team adds the new requirements to the DoD because it is more robust way of doing the work.

You can also check my answer for 9. Should the PO approve the DoD?

47. Angry stakeholders. What led to this?
Q: At the fifth Sprint Review, the stakeholders seem disappointed and angry. When asked about it, they say the product or system as being built will not meet their needs and will cost more than they anticipated spending, What led to this?
A) The stakeholders haven’t been using the Sprint Reviews to actively engage , and inspect and evaluate progress
B) Changes to the project plan were not adequately documented and shared. The change request procedure was not diligently followed
C) The PMO and its project managers have not been engaged adequately causing the project plan to become inaccurate
D) The Product Owner has not been interacting frequently with stakeholders keeping them aware of the progress.
E) The stakeholders were not allowed to attend daily scrum
F) The scrum master has not ensured transparency

Mikhail: Let’s go through all the options:
A) Looks good except that the PO is responsible for Key Stakeholder engagement. Probably there are better answers.
B) Wrong because Scrum does not have a “change request procedure”.
C) Wrong. Scrum does not have a Project Manager role.
D) The best option.
E) Wrong. Stakeholders have nothing to do at Daily Scrums.
F) Good enough. The whole team is responsible for transparency, however the SM should notice if there is a lack of transparency and help the team to address it.

48. How to do a perfect Sprint Planning?
Q: Creating a forecast for a sprint tends to run smoothly when the Product Backlog items that are discussed are well understood and actionable. Which approach would you recommend to ensure this state of Product Backlog at Sprint Planning?
A) The Development Team uses some time in each Sprint to analyse, estimate and design high ordered Product Backlog items.
B) A separate Scrum Team of business analysts and functional testers analyse high-ordered requirements one sprint ahead of development.
C) The Product Owner works with the stakeholders to prepare Product Backlog items outside of the sprint so the development team will not be disrupted.
D) The analysts on the Development Team document high ordered Product Backlog items during a Sprint when they are not busy working on the forecast.

Mikhail: A) Correct. The name of this activity is Product Backlog Refinement. However, why the PO is not mentioned here? The Scrum Guide says “Product Backlog refinement is the act of adding detail, estimates, and order to items in the Product Backlog. This is an ongoing process in which the Product Owner and the Development Team collaborate on the details of Product Backlog items.”
B) Wrong. Scrum does not have separate teams for business analysts.
C) This is a good option, but it won’t get enough clarity at the Sprint Planning. When the PO is ready with a new PB item, the PO should discuss it with the DT to make sure it is understood well before taking it into the next Sprint.
D) Wrong. Scrum recognizes only Developer role in the Development Team.

It looks like the correct answer is A. However, if it were my question, I would mention the PO in this option.

49. PM asks for a status report
Q: The Project Manager has asked for a status report to the Scrum Master about the progress. What should he do ?
A. Prepare it by himself
B. Tell the PO to prepare and submit to the Manager
C. Ask the DT to include the report into their Sprint Backlog
D. Tell the Manager that status will be visible during the Sprint Review

Mikhail: The best option is D (status will be visible at the Sprint Review).
A duty of the Scrum Team is to be transparent. Those who need information are responsible for getting it. So, the manager can investigate the artifacts of the Scrum Team (Product Backlog, Sprint Backlog) and visit the next Sprint Review.

50. All Scrum Teams must have a PO and SM
Q: All scrum teams must have a PO and SM. True or False?
A. False
B. True and they should be available 100% dedicated to the Scrum Team
C. True and the productivity and progress depends on their availability

Mikhail: C is correct. PO, SM and even Dev Team members can work on more than one Product at the same time, but productivity will suffer because of switching focus.

51. DT is unclear how to plan work for the Sprint
Q: The DT approaches the SM for advice as they are unclear about how to plan work for the Product Backlog Items selected for the Sprint. What should the SM do?
(not sure about other options)

A. tell the DT to figure out themselves
B. Ask the PO to adjust the PB items according to the technical expertise of the DT, so they can plan the work.

Mikhail: A is correct. The Scrum Guide says: Teams in Scrum are self-organizing and cross-functional. Self-organizing teams choose how best to accomplish their work, rather than being directed by others outside the team. Cross-functional teams have all competencies needed to accomplish the work without depending on others not part of the team.

52. The same Sprint start date for all teams
Q: Multiple Scrum Teams working on the same Product must have the same Sprint start date. Is this statement correct?

Mikhail: No, the statement is incorrect.
The Scrum framework does not require the same Sprint length or aligned Sprints for all teams. So, the start date can be different.

53. What may be delivered at the end of a Sprint?
Q: Which of these may a Development Team deliver at the end of a Sprint?
a. An increment of working software that is done
b. An increment of software with minor known bugs in it
c. Some sort of documentation
d. Failing unit test, to identify acceptance tests

Mikhail: The Scrum Guide contains:

“At the end of a Sprint, the new Increment must be “Done,” which means it must be in useable condition and meet the Scrum Team’s definition of “Done”.

a. Perfectly suits to this definition
b. Wrong because we do not know the DoD of the team in the question. So, we cannot tell are the minor bugs acceptable for a “Done” Increment.
c. and d. are wrong because the Scrum Guide says:

“Development Teams deliver an Increment of product functionality every Sprint.”

They cannot deliver only documentation or an unit test.

54. The customer wants a new feature
Q: In the middle of a Sprint, the customer decides that there are 2 new features they want. What should PO do? Select 2 answers.
a. Ask the Development Team to think about whether they can add these features to the current Sprint
b. The Scrum Master add these features to the current Sprint
c. Add it to the Product Backlog
d. Introduce these features at the next Daily Scrum

Mikhail: c. is definitely correct because the Product Backlog is the single source of requirements for any changes to be made to the product.
b. is wrong because the Scrum Guide says: “Only the Development Team can change its Sprint Backlog during a Sprint.”
d. is wrong because the PO cannot introduce the features at the Daily Scrum because he or she does not participate in it
a. is correct because the Sprint scope can be re-negotiated if the Sprint Goal and quality are out of danger (see a quote from the Scrum Guide below)

During the Sprint:
* No changes are made that would endanger the Sprint Goal;
* Quality goals do not decrease; and,
* Scope may be clarified and re-negotiated between the Product Owner and Development Team as more is learned.

55. PO thinks the team cannot deliver a story
Q: You are the scrum master that is new to scrum. PO comes to you halfway through the Sprint and says “I don’t feel like the development team will be able to meet the commitment to deliver the Product backlog item selected during Sprint Planning”. What you should do here?

a) Talk to the Dev team, challenge and inspire them to complete all the work so that they meet their commitment to the PO and have the forecasted velocity.
b) Advise the product owner that the dev team owns the Sprint Backlog and it is up to them to meet the commitment. No one tell the Dev team how to turn Product backlog into increment of potentially releasable functionality.
c) Add more people to Dev team to meet the commitment to PO.
d) Coach the PO that with complex software development you cannot promise the entire scope that was forecasted during Sprint planning. As more is learned during the sprint, work may emerge that affects the Sprint backlog.

Mikhail:
a) is not a good option. The Dev Team has no commitments to the PO. There is no goal in Scrum to meet the forecasted velocity by any price.
b) is correct. The Scrum Guide says: “No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality;” So, it up to the Dev Team to meet the commitment.
c) is definitely wrong because adding more people to a team decreases productivity in a short term and won’t help to meet the commitment.
d) Fair enough. Sometimes the Dev Team discovers completely unpredicted work during a Sprint and cannot deliver all the items. In this case the Sprint Scope should be negotiated with the PO as soon as possible.

56. PO and ordering items with external dependencies
Q: One of the top PB items depends on a component provided by another team (still in development). Should the DT take it into the next Sprint? Is it a better option to ask the PO to reorder the PB?

Mikhail: This question is about handling external dependencies in Scrum. The rule of thumb here is not to take any work into a Sprint if there are some unresolved external dependencies. The reason is the Dev team cannot take a commitment to finish the item in this case.
Another point to keep in mind is a piece of functionality should be delivered in every Sprint.

In real life I would ask the following questions at the Sprint Planning in this situation:
* Will the external component be delivered during this Sprint? Rarely the answer is “yes” if there is a person representing the external team and making the commitment.
* If the component is not delivered, will work on this item produce some valuable functionality for customers?

If the answers to the both questions are “no”, the dev team will take the next items from the Backlog into the Sprint.

The primary concern of the PO is the flow of value reflected in the ordering of product backlog. Timeline of the flow might be affected by such dependencies but doesn’t necessarily change the ordering.

57. Risks addressed in Scrum
Q: Which risks to software development are addressed by Scrum?

Mikhail: Scrum addresses the most of the risks involved in software development.
For example, Scrum addresses timescale of the planned work via Sprint Planning and fixed Sprint length. Scrum guarantees the best possible value will be delivered in the specified time frame.
Scrum addresses the risks related to the Team: missing skills or bad relationships. The Scrum Guide tells: “Development Teams are cross-functional, with all the skills as a team necessary to create a product Increment;” and “teams are self-organizing”. It means if some skills are missing, the team can organize itself to gain them. The same is with bad relationships. Teams can overcome them by ourselves with a help from the Scrum Master.
Scrum allows to mitigate the risk of an unstable or complex technology through Product Backlog management. The most risky items will be identified and put close to the top. They will be addressed early that guarantees minimal loses in the case if something goes wrong with the technology.
Complexity and unpredictability of requirements are addressed by Scrum via constant work of the PO with the Key Stakeholders and the Development Team (Sprint Reviews, Backlog refinement sessions, etc.)

58. Bad behavior of a developer
Q: A team practices pair programming. Jason is one team member about who everyone has come to you to complain about him. Anyone who pairs with him gets caught in design and architecture decision discussion.
As the Scrum Master what will your do (choose two)?

a) Raise a concern to HR and get Jason removed from the team.
b) Take Jason aside and express your concern over this behavior. Tell him to act as team player and comply to team decision.
c) You suggest to open it up with full team now so that is does not further worsen. You propose to help initiate this discussion but not being the one to start it.
d) You observe this in Retrospective whether discussion on design and architecture is initiated, if not then check how comfortable is everyone with the way it is handled in project.

Mikhail: This question relates to the group of questions where a team member behaves in a wrong way. There are following ideas for the Scrum Master how to handle this:
* As the Scrum Master you are responsible for supporting Scrum, facilitating Scrum events as requested and removing impediments. So, you definitely should take an action.
* Do not immediately suspect lack of commitment. It can be unfair and even harmful. Try to understand what’s going on. Find it out by asking the individual (privately) or someone who knows the individual (discreetly).
* Scrum Teams are self-organizing, so they can handle this for themselves. You should bring it up in the next Retrospective and try to come to a solution that everyone is happy with.

So, the correct answers are c and d.
Definitely, it needs to be discussed with the team. However, it is worth to understand what’s going on before this. Sometimes the root cause of the bad behavior is very different than it seems. In many questions about harmful developer behavior B would be a good option if it was formulated like “Take Jason aside and ask why does he behave in this way”.
As usually, there is no need to wait for a formal event to inspect and adapt. This can be done as soon as the issue is identified.

59. DoD is changed in the middle of a Sprint
Q: After the last release in the production the Key Stakeholders started complain on performance issues. Even the PO agrees, he comes to the Scrum Master. What should the Scrum Master do? (choose one)

a) Tell the PO that dev team owns the DoD and it is their duty to decide on acceptable performance standard
b) Encourage the PO to bring this up to the team so that team can come up with improved DoD, with strong SLA requirements for performance issues
c) Wait till retrospective because this is the appropriate time for dev team to re-consider the DoD

Mikhail: Of course, the PO needs to bring up the concerns to the team. I think it is better to do as early as possible.
However, changing the DoD during a Sprint seems not a good practice because of 2 reasons:
* If the DoD is strengthen in a middle of a Sprint, it could affect the Sprint Goal because items from the Sprint Backlog will require more time to be completed.
* Sometimes a Dev Team could desire to weaken the DoD in a middle of a Sprint to make some unfinished items “complete”. In my opinion it could endanger quality.

So, the best time to change the DoD is at the Retrospective right before the next Sprint.

60. Developer's opinion is not heard
Q: A dev team member complains at the Retrospective that his comments and suggestions were ignored throughout the Sprint. Which three values are we touching here?
a. Focus
b. Commitment
c. Courage
d. Respect
e. Openness

Mikhail: The Scrum Guide itself does not contain details about the Scrum Values. However, I found a very good series of articles on this topic at Scrum.org that explains every value:
Focus
Openness
Courage
Commitment
Rspect

I think the following values were touched in the question: openness, courage and respect (c, d, e):

Openness:
Openness enables team members to share their perspectives, feel heard by their peers, and be able to support team decisions.

Courage:
It takes courage to share a dissenting opinion with a team member and engage in productive conflict.
It takes courage to admit our mistakes. This could apply to our technical work, our decisions, or how we conduct ourselves.

Respect:
When there is respect for all opinions and perspectives, we can ensure everyone has the opportunity to be heard. When we feel we have been heard, it is possible to fully support team decisions even if the decision was not our preference.

61. Sources of Value for PO
Q: As a Product Owner, if you had access to the following individuals, what sources might you consult with when considering the value of a product?
A. Sales Executive or Sales Leader
B. CEO
C. Customers and Prospects
D. Market research results and analyst reports
E. Development Team

Mikhail: Actually, the Product Owner can work with anyone any time (possibly during Product Backlog Refinement and other activities) who can supply good ideas to capture more value for the Product.
In order to maximize value, the PO should identify the Key Stakeholders for the Product, and involve them as necessary throughout the development effort.

There is a good article at Scrum.org that explains everything about the Key Stakeholders. It divides the Key Stakeholders into three broad categories:

  • The Users – The human people who actually use the Product. Sometimes the Development team acts as a “Production Support Engineer” user
  • The External Customers – The people responsible for paying to use the Product
  • The Internal Customers – The people responsible for making the funding decisions for the Product development effort

The Scrum Glossary gives a definition:

A Key Stakeholder is a person external to the Scrum Team with a specific interest in and knowledge of a product that is required for incremental discovery. Represented by the Product Owner and actively engaged with the Scrum Team at Sprint Review.

So, the PO might consider all the suggested options. However, we can try to arrange them:
C. Customers and Prospects (The Users)
B. CEO (The Internal Customers)
A. Sales Executive or Sales Leader (specific interest in and knowledge of the Product)
E. Development Team (sometimes acts as a “Production Support Engineer” user, can give useful feedback during Product Backlog Refinement and other activities)
D. Market research results and analyst reports

62. Who identifies dependencies between the teams?
Q: You’re a product lead with a good track record and the organization has asked you to take the lead of a new product. The product will have 6 teams working on it but they are all new to Scrum. You’re starting to form a Product Backlog. How would you minimize dependencies between Scrum Teams?
(A): You identify the dependencies and re-order the Product Backlog for them.
(B): You work with the Development Teams on how to best parse the work.

Mikhail: Actually, it is easy to answer using the Nexus Guide. It has special events for identifying and minimizing dependencies between the teams and forecasting which team will deliver which Product Backlog items: Refinement and Nexus Sprint Planning. Both meetings involve representatives from all the teams.
So, the correct answer is B.

There is a good paper describing this process in detail: Cross-Team Refinement in Nexus™

63. What to do with process improvements after Retro?
Q: Q. After a Retrospective there are few high priority action items identified by the team. What would be the next course of action?
A. Add at least one high priority item into the Product Backlog
B. Add at least one high priority item into the Sprint Backlog
C. Aim for highest priority item to be implemented in the next Sprint
D. Add the highest priority item into the Product Backlog

Mikhail: A and D are wrong because they suggest adding a team process improvement directly into the Product Backlog. Remember, the Product Backlog lists all features, functions, requirements, enhancements, and fixes that constitute the changes to be made to the product in future releases.

B (add a process improvement into the Sprint Backlog) looks good. However, the current Sprint is almost over at the time of Retrospective. The scope of the next Sprint will be defined at the following Sprint Planning. So, B is not the best choice.

The Scrum Guide contains: The Sprint Backlog makes visible all the work that the Development Team identifies as necessary to meet the Sprint Goal. To ensure continuous improvement, it includes at least one high priority process improvement identified in the previous Retrospective meeting.

So, C option is the best.

64. Responsibilities of Dev Team
Q: Choose three responsibilities of a self-organizing Development Team:
A. Report daily progress to stakeholders
B. Do the work planned in the Sprint Backlog
C. Increase velocity
D. Pull Product Backlog items for the Sprint
E. Reorder the Product Backlog
F. Set the time for the Daily Scrum

Mikhail: A. Wrong. There is no such a duty.
B. Correct
C. Wrong. There is no a formal commitment for this.
D. Correct. The Guide states: “The number of items selected from the Product Backlog for the Sprint is solely up to the Development Team.” I would rephrase it as the DT pulls items from the PB until it feels it is enough.
E. Wrong. This is a PO responsibility.
F. Correct

65. Productivity after adding a new team
Q: There was one Scrum Team working on a product. According to the last decision, a new Scrum team was added to work on the same product. What does happen with the productivity of the first team?”

Check 1 Answer:
A. The productivity of the first team decreases
B. The productivity of the first team increases
C. The productivity of the first team remains unchanged

Mikhail: The correct answer is A. Productivity will decrease because the first team should spend time on interaction with the other team and resolve dependencies. In the very beginning the productivity will drop even more because members of the first team will have to do some knowledge transfer to the new team.

66. Responsibility of SM @ Retro
Q: During a Sprint Retrospective, for what is the Scrum Master responsible?
A. Facilitating and also participating as a Scrum team member.
B. Summarizing and reporting the discussions to management.
C. Acting as a scribe to capture the Development Team’s answers.
D. Prioritizing the resulting action items.

Mikhail: A. Correct. The Scrum Guide states: “The Scrum Master ensures that the meeting is positive and productive. The Scrum Master participates as a peer team member in the Retrospective from the accountability over the Scrum process.”
B. Wrong because management is not part of Scrum
C. Wrong because there is no Scribe role in Scrum
D. Wrong because the whole team should do it

67. When to adjust practices?
Q: When does a Development Team make adjustments to its engineering practices?
A. During Sprint Planning.
B. After they have been discussed and agreed to at the Sprint Retrospective.
C. Whenever needed.
D. Before a Sprint begins.
E. Prior to starting a project.

Mikhail: The correct answer is C. Teams in Scrum are self-organized. There is no need to wait until a formal event. Scrum events give formal opportunities to inspect and adapt. However, any adjustments to practices or processes can be made whenever it is needed.

68. When is discovered work added to SB?
Q: During a Sprint, when is new work or further decomposition of work added to the Sprint Backlog?
A. When the Product Owner identities a new work.
B. When the Scrum Master has time to enter them.
C. As soon as possible after they are identified.
D. During the Daily Scrum after the Development Team approves them

Mikhail: The correct answer is C “as soon as possible”. The Scrum Guide clarifies it:
“As new work is required, the Development Team adds it to the Sprint Backlog.”
“The Sprint Backlog is a highly visible, real-time picture of the work that the Development Team plans to accomplish during the Sprint”
There is no need to wait for the Daily Scrum to approve it.

69. Max time for PB Refinement?
Q: How much time should be spent carrying out Product Backlog Refinement?
A. As much as the Product Owner and Development Team agree is necessary to create enough ready Product Backlog Items
B. Up to 10% of the capacity of the Development Team
C. As much as the Product Owner deems necessary to create enough ready Product Backlog Items
D. Up to 10% of the capacity of the Development Team in a typical Sprint, but as much as 90% in early Sprints

Mikhail: At first glance it seems that answer should be B. However, it is A. The Scrum Guide states:
“This is an ongoing process in which the Product Owner and the Development Team collaborate on the details of Product Backlog items.”
“Refinement usually consumes no more than 10% of the capacity of the Development Team.”

So, Refinement takes as much time as the PO and the DT agree. Usually, it takes not more than 10% of the total Sprint time.

70. 10 people in a team?
Q: A new Developer joins the Development Team taking the total number to 10 people. As a Scrum Master, What should you do?
A. Instruct the Development Team to split into 2 teams with 5 Developers in each
B. Instruct the Development Team to split into 2 teams, they should decide the appropriate sizes
C. Raise the increased team size as a potential impediment and help the Development Team decide what to do about it
D. Do nothing, the Development Team must fix its own issues

Mikhail: The Scrum Guide advises optimal team size of 3 to 9 people. A and B are wrong because teams are self-organizing. C is better than D because the Dev Team can be not aware of the potential risks. Your job as the Scrum Master is to clarify it and facilitate coming to a solution.

71. What happens in Daily Scrum?
Q: What happens in Daily Scrum?
A. Development team plans work for next 24 hours
B. Inspect work since last daily scrum
C. Forecast upcoming sprint work

My confusion: A and B looks correct. C is not clear to me, do they mean upcoming work of the current sprint or the work of upcoming sprint?

Mikhail: The Scrum Guide contains “The Daily Scrum is held every day of the Sprint. At it, the Development Team plans work for the next 24 hours. This optimizes team collaboration and performance by inspecting the work since the last Daily Scrum and forecasting upcoming Sprint work.”

So, all the options are correct.

72. Should many DTs integrate their increments?
Q:When many Scrum Teams are working on the same Product, should all of their Increments be integrated every Sprint?
A. No, that is far too hard and must be done in a hardening Sprint.
B. No, each Scrum Team stands alone.
C. Yes, but only for Scrum Teams whose work has dependencies.
D. Yes, otherwise the Product Owner (and stakeholders) may not be able to accurately inspect what is done.

Mikhail:The Nexus Guide states: “A Nexus consists of multiple cross-functional Scrum Teams working together to deliver a potentially releasable Integrated Increment at least by the end of each Sprint.”
So, all the teams should integrate their increments by the end of each Sprint. The answer is D.

73. Purpose of a Sprint
Q:The purpose of a Sprint is to produce a done Increment of Product.
A. True
B. False

Mikhail: True (A). The Scrum Guide states: “The heart of Scrum is a Sprint, a time-box of one month or less during which a “Done”, useable, and potentially releasable product Increment is created.”

74. What belongs to the DT?
Q: I think, these two questions from your quiz contradict each other:

Q1 :Who creates the Increment?
A1: Only members of the Development Team create the Increment.

Q2: What belongs solely to the Development Team?
I think, the answer here should include “Increment”, but the answer was : The Sprint Backlog

Mikhail: I think, there is no any contradiction between the questions. The Scrum Guide contains:
“Only members of the Development Team create the Increment.”
“Only the Development Team can change its Sprint Backlog during a Sprint. The Sprint Backlog is a highly visible, real-time picture of the work that the Development Team plans to accomplish during the Sprint, and it belongs solely to the Development Team.”

So, according to the Scrum Guide, the both answers are correct.

It is not written in the Guide, but in fact, when the Increment is created, it does not belong to the Dev Team anymore. For example, someone hired a dev team to create a product. When the job is done, the product belongs to the person who funded the project.

    Hi Mikhail, i found one of the question taking about the transparency of an increment
    in order to enhance it, what could be the options,
    A) doing all work defining DOD
    B) updating sprint in a tool
    C) reporting progress to our stakeholders
    D) keep trakcing of the unaccomplised work in separate sprint ?

    i would say A is corect but it assures only the completion of work not transparency , B or C could help

    Thanks in advance

    1. mlapshin (Post author)

      Hi,

      The best way to support transparency is to keep all the Scrum Artifacts (Product Backlog, Sprint Backlog and the Increment) in a good condition and make them available to the all interested parties.
      What does it mean to keep the Increment in a good condition? It means doing all the work defined in the DoD for every Item that is a part of the Increment. Everyone should understand what “Done” means.
      Updating Sprint in a tool could help a little bit, but it is not a general solution.
      Reporting progress to the Stakeholders won’t help if the Increment contains Items which are not processed according to the DoD.
      D) won’t help to improve transparency because a Sprint devoted to the unaccomplished work is not different from a standard Sprint.

      So, the answer is A).

      Thanks,
      –Mikhail

    Hi Mikhail,

    i have another question regarding PBI
    When is implementation of a Product Backlog item considered complete?
    a. is it At the end of the sprint

    b.When all work in the Sprint Backlog related to the item is finished

    c. When the item has no work remaining in order to be potentially released

    d.When the reports shows that the item passes all acceptance criteria

    i was thinking in C, as it is close to be potentially released, as B still waiting for testing no sure it will be released.

    Thanks in advance

    1. mlapshin (Post author)

      Hi,

      I would also select C. It means the item conforms to the Definition of Done. Without following the Definition of Done, it is not clear whether all work done on a item or not. So, B is not the best option.

      Thanks,
      –Mikhail

    Hello Mikhail,

    I have a question regarding the velocity:
    ———–
    Mikhail: I re-phrased the question.

    If a team works on a Product for several Sprints and another team joins. What happens to the velocity of the first team?

    1. mlapshin (Post author)

      Of course, the velocity will decrease for some period of time because the first team will spend time for on-boarding the second team. Also, it will be harder to divide work between the teams because of possible dependencies.

      Thanks,
      –Mikhail

  4. emy_hm

    Hi Mikhail,
    another question please

    When does the second Sprint start?

    in Scrum guide, it is written is starts immediately after the finish of the first print.

    Thanks

    1. mlapshin (Post author)

      Correct. The next Sprint starts immediately when the previous Sprint ends. There is no time in between. It is also not allowed to extend Sprints arbitrarily.

      Thanks,
      –Mikhail

    Hi Mikhail,
    I”m so sorry, i didnt know that ,
    i formulated my questions,
    1) How time- boxing can help the self-organization team, as i didnt find any info in scrum guide book
    2) regarding finding a technical write to create user documentation, still the DT responsible for it or it should have external one to help?
    3) when a stk is unhappy regarding increment or DT work, should we discuss this in sprint Retropsective and employ some perfomenace measurement or it is too much ?
    4) a done increment is the released product only or also what PO define too ?or when we do not have more work to do in the product
    Thanks in advance for your help

      Hi,

      Thanks for reformulating the questions. Now it is safe to discuss it here.

      1) How time- boxing can help the self-organization team, as i didnt find any info in scrum guide book
      Mikhail: You are right, the Scrum Guide restricts duration of the meetings, but does not explain directly why it is useful.
      I found the reasons are formulated well here: https://www.benday.com/2014/07/21/timeboxes-scrum-operate-series-sprints/
      * Time boxes are deadlines. It creates a sense of urgency so that you focus on actually accomplishing something.
      * Time to work. Make sure that meetings don’t go on forever.
      * It improves transparency. It forces you to pause and take stock of what you’ve done.

      2) regarding finding a technical write to create user documentation, still the DT responsible for it or it should have external one to help?
      Mikhail: For sure, the Dev Team is responsible for all work necessary to produce the Increment, including the user documentation.

      3) when a stk is unhappy regarding increment or DT work, should we discuss this in sprint Retropsective and employ some perfomenace measurement or it is too much ?
      Mikhail: Definitely, it should be discussed at the Retrospective and a plan how to fix it should be developed. Performance measurement does not sound right for Scrum.

      4) a done increment is the released product only or also what PO define too ?or when we do not have more work to do in the product
      Mikhail: The Increment should be always in “Done” state and can be immediately released by a PO decision. All items marked as “Done” should conform to the Definition of Done. A Product is never complete. There are always improvements that can be made.

      Best Regards,
      –Mikhail

        Thanks a lot Mikhail for your help,

        regarding point 3) what options we can have, the first one is to discuss this in Retrospective, then,
        1) PO can simply say it is up to DT to decide on the performance-> but it sounds like get out STK, you do not have opinion here
        2) PO need to talk privately to DT about this problem-> to find a way with DT
        3)put some measurement perf on the PB , -> as you said do not sound right here

        Mikhail: Probably, I did not understand the question. It is perfectly right to have requirements to performance in the DoD. For example, “Any page should be loaded in 1 second or faster”. I thought you are asking something about individual performance.
        Performance requirements can be added to the Product Backlog too.

        another question please
        when can we say that PBI is done ?
        A) when there is no work remaining and it is ready now to be released, Correct
        B) end of sprint, incorrect as we are not sure if it is really done and ready or not
        C) when all work in sprint backlog is done -Incorrect because we are not sure if it is done correctly or not

        Mikhail: Good analysis. Agree, A option is correct.
        Thanks a lot in advance

    Hey Mikhail,

    I have few questions to you. Maybe you can help me out.

    Scrum Values:
    One of the Developers says that others in the Development Team do not listen to his ideas. Which Scrum Values are not followed in this situation?
    I would select openness, courage and respect, however focus and commitment also may be correct.

      Hi,

      For the affected Scrum Values I would pick the same set: openness, respect and courage (courage to listen and accept someone’s else ideas).

      I had to delete the second question because I feel it is copyrighted. However, I completely agree with your analysis of the options.

      Thanks,
      –Mikhail

        I rephrased 2nd question, but it is not a problem at all 🙂 thanks for confirmation!

  8. Bupesh

    Hi Mikhail,

    My query is about the skill sets of the DT Team. Should the DT Team have skills of various layers of software architecture or should there be specialist in each area (e.g. Database) who should be in the DT. Is there any guidance or recommendation in this front?

    Thanks

    1. mlapshin (Post author)

      Hi,

      Thanks for the great question.

      First of all, a Dev Team should be cross-functional to be able to do all the required work for PB Items (design, coding, testing, documentation, etc.)

      Then, Scrum better fits for “feature” teams when a team is responsible for a whole feature including all the intermediate layers. The reason is in less dependencies on other teams and better transparency of the completed work.

      Best Regards,
      –Mikhail

  9. emy_hm

    Hi Mikhail,

    can you help me with this questions, i formalized with my own words

    1. PO must ship the increment when
    A) it makes sense for him to do it ? -> correct as he is the one who decide to release it or not
    B) just to make sure that DT is done from his work during.->incorrect, DT is doing their job anyway
    C) when it is good product without errors->incorrect,it has to be tested and quality etcc

    2. during a sprint, when new work is added to sprint backlog,
    A) when PO wants to add more-> incorrect. has to be approved by DT too ?
    B) when DT approve it during daily scrum->incorrect in daily scrum, they pull the agreed items into the sprint
    C) As soon as possible after they are identified-> correct, PO put them in PB and then plan when they are added in the sprint

    3, in retrospective what PO is responsible for
    be scrum team member-> correct, and coordinate the event if needed
    collect info for backlog-> incorrect, do not need this step
    report discuss to STK-> incorrect, too early as they have sprint review

    4. Daily scrum output , choose 2
    A.complete task so SM can plan the next days, correct
    B.report for upper mgmt-> incorrect, has nothing to do with mgmt
    c. Sprint progress report for STK->incorrect
    d.New impediments for the Scrum Master-> correct to work on it
    e.most important work to be done next -> correct , the plan to do it

    Im confused between D and E

    5. DT team found it is too much work to do in the sprint
    A. hire new colleagues-> no .
    B.change the definition of “Done” and start to work it.-> not without the PO
    c.work with the Product Owner to remove some work-> Yes, PO needs to be informed
    D.wait until the sprint review and inform thr PO,-> would be too late

    6. When adjusting sprint backlog work, it is only DT or also with PO

    7. how SM ensure that PO and DT have good communication

    a. Act as a go-between them ??-> incorrect as it doesnt ensure that they have good communiation
    B. watching their communication was and help in it ->correct, i see more robust.

    8. the length of the Sprint ? (two answers)

    a. Same time as between 2 sprints -> wrong because the second sprint start immediately after the previous done
    b.Sprint length is calculated during Sprint Planning, to see how much work needs to be done without testing – incorrect, it has time fixed 1 month
    d.Sprint should have the same length so DT can work on it -> not necessary
    E.sprint is no more than 1 month-> as per scrum guide

    9. How Increment is valuable? 2
    A) reduce cost-> has no value
    B) customer satisfaction->Yes, he is the one who will use it
    C)Delivered on time-> no
    D) has all the features that PO waits for it->Yes as per the definition of done

    Thanks a lot in advance

    Emy

    1. Twister

      Hey,

      From my experience;

      1. A) is only correct option. It is PO decision to release the increment.

      2. A) false; only DT can change the Sprint Backlog so he needs to discuss it with DT first
      B) false -> PO can attend the daily scrum, but can’t participate in it so there won’t be discussion with DT to agree new work
      C) correct -> as soon as possible after discussion with DT. DT can add this work to sprint, but first they need to check their current Sprint Goal as new work can jeopardise it.

      3. A) is correct; PO is Scrum Team member. He participate in Sprint Retrospective as Scrum Team member.
      B) is false as Retrospective is around process and not product baclog
      C) is false as stakeholders are not interested in retrospective outcomes but they are interested in product – and they have sprint review for that

      4. A) false – SM doesn’t plan next days for DT. DT should do it by themselves
      D) and E) are correct

      5. A) false – They should be self-organized so they can change their team structure but not during the sprint. They also should be crossfunctional and should be able to deliver work according to Sprint Goal
      B) false – they cannot change DoD in the middle of sprint as some work can already be finished and by changing DoD in the middle of the sprint, they won’t be able to tell if already finished items are still finished. They can change it on Sprint Retrospective meeting
      C) correct – if they are not able to finish some work which they took to the sprint, they should inform PO and get it sorted
      D) false – PO should make a decision, what to do as Sprint Goal can be in danger

      6. Sprint Backlog work is adjusted on the daily basis through Daily Scrum – new work is added as it emerges from the work which is already in the Sprint Backlog (by DT only). If you are talking about adding completely new work to the Sprint Backlog, then DT should discuss it with Product Owner because of agreed Sprint Goal

      7. The Scrum Guide says: the SM helps the PO to understand and practice agility. Agility means using the most effective ways to collaborate. Direct collaboration between the PO and the DT is the most effective one. So, the best technique for SM is to monitor communications between the DT and the PO and facilitate direct collaboration.
      So correct answer is B)

      8. only E) is correct. Sprint is a time-box of one month or less during which a “Done”. Once a Sprint begins, its duration is fixed and cannot be shortened or lengthened. So it can be changed – but only as a conclusion from Sprint Retrospective

      9. A) and B) are correct;
      Take a look at the Evidence Management Guide, you will find A and B among the Key Value Measures in Current Value section.

      1. emy_hm

        Hello Twister, thanks a lot for the help,
        only 2 questions:

        8) the length of the Sprint ? (two answers),
        a. Same time as between 2 sprints -> wrong because the second sprint start immediately after the previous done

        b.Sprint length is calculated during Sprint Planning, to see how much work needs to be done without testing – Incorrect
        d.Sprint should have the same length so DT can work on it -> not necessary
        E.sprint is no more than 1 month-> as per scrum guide

        Agree with you on E, but we need 2 choices, so B also or ?

        6. When adjusting sprint backlog work, it is only DT or also with PO,
        i believe my question was not clear;
        when DT find that the work planned is too much and need to be reviewed, who should be present when reviewing and adjusting the sprint work, is it only DT , they don’t need the PO ?

        Thanks a lot in advance

        1. Twister

          Hey Emy,

          8: I believe we are missing one option here. Sprint length can be inspected and adapted on Sprint Retrospective as this is only event, when process can evolve. This decision however shouldn’t be taken lightly as Sprint is the hearth of the Scrum. You can check these two references: https://www.scrum.org/index.php/forum/scrum-forum/17995/sprint-length and https://www.scrum.org/index.php/forum/scrum-forum/5656/sprint-questions

          6. So when DT finds out they have more work than they are capable to handle, they should review and adjust sprint work with Product Owner – so DT and Product Owner is the right answer.
          None of them can do it on their own.
          According to Scrum Guide:
          – “Optimizing the value of the work the Development Team performs” is the PO’s job.
          – “Only the Development Team can change its Sprint Backlog during a Sprint. The Sprint Backlog is a highly visible, real-time picture of the work that the Development Team plans to accomplish during the Sprint, and it belongs solely to the Development Team.”
          – “They [Development Team] are self-organizing. No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality;”

          Gland I could help!

      Hi Emy,

      Thanks for re-phrasing the questions. So, it is safe have them published here.

      Let me answer a couple of questions at a time.

      1. PO must ship the increment when
      A) it makes sense for him to do it ? -> correct as he is the one who decide to release it or not
      B) just to make sure that DT is done from his work during.->incorrect, DT is doing their job anyway
      C) when it is good product without errors->incorrect,it has to be tested and quality etcc
      Mikhail: agree, A) is correct

      2. during a sprint, when new work is added to sprint backlog,
      A) when PO wants to add more-> incorrect. has to be approved by DT too ?
      B) when DT approve it during daily scrum->incorrect in daily scrum, they pull the agreed items into the sprint
      C) As soon as possible after they are identified-> correct, PO put them in PB and then plan when they are added in the sprint
      Mikhail: C) is correct. However, the Dev Team should discuss the new work with the PO.

    Hi Mikhail,
    I need help finding the correct answer for the following questions. I have modified the questions a little and removed some of the suggested answers

    1.In sytuation where user acceptance testing is required before the increment can be put into production, manager proposes to have this testing done every fourth Sprint because so far the feedback from it was disrupting work in Sprints. What do you think Is this a good idea?
    I think it’s a bad idea but I don’t know which answer might be better

    a) Bad idea because the Product Increment won’t be transparent and the feedback loops is too long
    b) It depends on what is stated in their DoD

    2. DELETED

    3. DELETED

    4.Six new teams have been created to build one product. A few of the developers on one of the DT ask the SM how to coordinate their work with the other teams. SM should teach them that it is their responsibility to work with the other teams to create an integrated Increment ?

    5.This statement is false regarding the nature of large-scale scrum ?
    One person working on multiple ST is often less productive than one focused on the Sprint Backlog of a single ST
    False ?

    6.One ST is developing a product. They track how much software they produce as velocity. Their current velocity in 20. A second team will be added to work on the same product. What is the most likely impact on the velocity of the original team? velocity is likely to decreas or r velocity is likely to increase or velocity will be the same ?

    7. DELETED

    8. In sprint Planning a DT works with the PO to create a forecaste for the Sprint. A forecaste is a selection of PBi that the DTdeems feasible to get done by end of the Sprint. Select 1 thing that explain what Done means.
    a) All work for which enough expertise and skills are actually present in the Development Team
    b) Having in Increment of software that could be released to end users

      Hi,

      A lot of questions!
      Thanks for re-phrasing them, so we can keep them published.
      I will answer the questions one by one when I have time.

      1.In situation where user acceptance testing is required before the increment can be put into production, manager proposes to have this testing done every fourth Sprint because so far the feedback from it was disrupting work in Sprints. What do you think Is this a good idea?
      I think it’s a bad idea but I don’t know which answer might be better

      a) Bad idea because the Product Increment won’t be transparent and the feedback loops is too long
      b) It depends on what is stated in their DoD

      A) is the better option here. “Every fourth Sprint” means that Increments delivered in the previous three Sprints are not completely “Done”, they are not transparent. Probably, the testing will find something needs improvement. It means the feedback loop is 4 Sprints in this case, it is too long.

      Any item that is delivered in a Sprint should be completely “Done”, ready to be released immediately. So, according to the question, items are not “Done. It does not depend on the DoD, so B) option does not make sense.

      Best Regards,
      –Mikhail

      Hi,

      I started reading and answering the questions and found many of them are almost unchanged (especially the options). So, I had to delete them.

      Answering the remaining questions:

      4.Six new teams have been created to build one product. A few of the developers on one of the DT ask the SM how to coordinate their work with the other teams. SM should teach them that it is their responsibility to work with the other teams to create an integrated Increment ?
      Mikhail: Correct, the teams should find a way to coordinate with each other to be able to produce an integrated Increment. Read the Nexus Guide on this topic. The SM also could advise some techniques on how to do it.

      5.This statement is false regarding the nature of large-scale scrum ?
      One person working on multiple ST is often less productive than one focused on the Sprint Backlog of a single ST
      False ?
      Mikhail: I would agree. Switching between teams, areas and tasks always takes time. So, a Developer usually will be more productive working in one team.
      Frequently Scrum Masters work for two or more teams. For Product Owners it is not recommended because it is quite challenging.

      Thanks,
      –Mikhail

      6.One ST is developing a product. They track how much software they produce as velocity. Their current velocity in 20. A second team will be added to work on the same product. What is the most likely impact on the velocity of the original team? velocity is likely to decreas or r velocity is likely to increase or velocity will be the same ?

      The velocity of the original team will drop for several weeks. This time is required to do knowledge transfer to the second team and resolve possible dependencies.

      8. In sprint Planning a DT works with the PO to create a forecast for the Sprint. A forecast is a selection of PB items that the DT deems feasible to get done by end of the Sprint. Select 1 thing that explain what Done means.
      a) All work for which enough expertise and skills are actually present in the Development Team
      b) Having in Increment of software that could be released to end users
      i think that b

      Mikhail: Yes, that is b) It should be possible to release the Increment immediately if the PO decides doing it.

      1. skafanka87

        thank you very much :):):)
        I have corrected the content of previous questions. I will be grateful if you help me.

        2. Customer just started using the product but are dissatisfied because everything works slowly. 2 answers
        A Team should decides on the standards of functionality
        B Tell PO how should talk with team about this situation
        C Inform Po that he may put the results test performance in the Product Backlog and he may express concern
        For me b and c sounds good

        3 You are SM for few teams (ofcourse working on the same product backlog) and few people from Dev team is complaining that in next few sprints they
        will need full time help from person which is not in part of any of these teams
        A Think about techniques of increasing ST number working on the same product backlog without creating dependencies between them
        B Someone from one of your teams volontuered to switch places in team with that external person
        C Create new temporary team with that external person and people from your teams, working partialy in that person domain and partialy for you teams

        7 When I can say that my ST team is self organizing?
        A My team is able to resolve conficts by temselves
        B team is creative and continously finds new possibilities
        C team always knows curent Sprint progress and knows how to deliver the spring backlog items

        For me A and C.

        9.PO estimated the project to take 7 Sprints based on the average velocity in the previous release ( was 13 completed units of work per Sprint.) Development is 3 Sprints underway, with four more Sprint to go until the release. Product Backlog has been stable.
        a) The DT sets the open work aside to be performed in one or more release Sprint. They remind Tom to find funding for enough Release Sprints in which this remaining work can be done. Up to one release Sprint per three development Sprints may be required. It is Tom’s role to inform user and stakeholders of the impact on the release date.
        b ) The DT informs Tom that the progress he has perceived to date is not correct. The increment is not releasable. They give Tom their estimate of the effort it would take to get the past work Done, and suggest doing that work first before proceeding with new features. The team also re-estimates the effort to completely do the project or to cancel.

        For me A is correct, in answer b I don’t like “cancel” 😉

        10 Is it acceptable in scrum framework to introduce one sprint dedicated only for testing and checking if we are ready to release ? –

        11. PO envisioning a project for a new release of her Product. PO made a projection of a release date based upon a sustained velocity of 17 completed units of work per Sprint. Over the first three Sprints , the average velocity was 13 for work that the DT estimated as 90% done. The DT, feeling the need to meet the plan, figured that a velocity of 17 was within their reach.
        this statment is true ? There’s less initial disruption than reorganizing into new teams. As they start, they will discover what works best, and how to potentially re-organize toward this.

        12. How to check if the PO is interacting with the DT enough throughout a Sprint ?

        a) PO is satisfied with the Increment at the Sprint
        b) When PO has conveyed all information at the Sprint Planning to make his/her presence during the Sprint optional.

        A?

        13 During almost every daily scrum one person is talking for verly long wha as SM I can suggest ?
        a”b”c”d” suggest using some king of token which will allowe only one person holding it to speak , or meaybe use some kind of timer ? Talk privately with that person coaching him how daily should look like, or maybe coaching the whole DT helping them to solve that problem themselves.

          Hi,

          Now the questions look much better.
          I will answer them 2-3 at a time.

          2. Customer just started using the product but are dissatisfied because everything works slowly. 2 answers
          A Team should decides on the standards of functionality
          B Tell PO how should talk with team about this situation
          C Inform Po that he may put the results test performance in the Product Backlog and he may express concern
          For me b and c sounds good

          Mikhail: Agree with your choice.
          The question is asking how to handle non-functional requirements (i.e. performance, security, etc.)
          A) is not a good option because non-functional requirements, of course, should be discussed with the PO.

          3 You are SM for few teams (ofcourse working on the same product backlog) and few people from Dev team is complaining that in next few sprints they will need full time help from person which is not in part of any of these teams
          A Think about techniques of increasing ST number working on the same product backlog without creating dependencies between them
          B Someone from one of your teams volontuered to switch places in team with that external person
          C Create new temporary team with that external person and people from your teams, working partialy in that person domain and partialy for you teams

          Mikhail: Teams in Scrum should be cross-functional. So, B and C are correct. They allow to gain the missing domain knowledge from the external person,
          I do not see how A (increasing number of teams) can help unless the external person will be in one of the new teams.

          7 When I can say that my ST team is self organizing?
          A My team is able to resolve conficts by temselves
          B team is creative and continously finds new possibilities
          C team always knows curent Sprint progress and knows how to deliver the spring backlog items

          For me A and C.
          Mikhail: If I need to select 2 of the 3 options, I agree with your choice: A and C.

            Mikhail: who is Tom? Is he the PO?
            A is not correct because it assumes “release Sprints” which is against Scrum rules.
            B is correct. “Cancel” option is rarely exercised.

            10 Is it acceptable in scrum framework to introduce one sprint dedicated only for testing and checking if we are ready to release ? –

            For sure the answer is “No”. Any Sprint should deliver some user functionality no matter how small it is.

            11. PO envisioning a project for a new release of her Product. PO made a projection of a release date based upon a sustained velocity of 17 completed units of work per Sprint. Over the first three Sprints , the average velocity was 13 for work that the DT estimated as 90% done. The DT, feeling the need to meet the plan, figured that a velocity of 17 was within their reach.
            this statment is true ? There’s less initial disruption than reorganizing into new teams. As they start, they will discover what works best, and how to potentially re-organize toward this.

            Mikhail: I see the team cannot reach the velocity of 17 units. However, they spent only 3 Sprints. Probably, velocity could raise after of a couple of Sprints, but it is not 100%. So, I would not base estimations on 17 units of work per week.
            It looks like only one team is working on the Product, so there is no need to do any reorganizations.

            Thanks,
            –Mikhail

          The last 2 questions!

          12. How to check if the PO is interacting with the DT enough throughout a Sprint ?

          a) PO is satisfied with the Increment at the Sprint
          b) When PO has conveyed all information at the Sprint Planning to make his/her presence during the Sprint optional.

          A?

          Mikhail: correct, A)

          13 During almost every daily scrum one person is talking for verly long wha as SM I can suggest ?
          a”b”c”d” suggest using some king of token which will allowe only one person holding it to speak , or meaybe use some kind of timer ? Talk privately with that person coaching him how daily should look like, or maybe coaching the whole DT helping them to solve that problem themselves.

          It is a good question. This is the primary responsibility of the SM to teach the team how to conduct Daily Scrums. The SM should explain why such behavior is harmful to the whole team.
          The SM could bring this to the Retrospective.
          Talking privately to the person (as the first step) is also a good idea.

          Thanks,
          –Mikhail

        Hi John,

        congratulations für your success.
        as Im preparing too for PSM2, i would like to know, is it only situational questions ? or we can have one or two questions like PSM1, definition of done, who attend daily scrum etcc

        from where we can practice because i didnt find so examples on the internet, they are all PSM1.

        Thanks in advance

    Hi Mikhail,

    I’m preparing for my PSM2, i didn’t find much test exam on the internet to practice.
    I believe the exam is the same as PSM1 but more into Situational questions? shall we study from other material as well or Scrum guide is enough.

    Thanks in advance

    1. mlapshin (Post author)

      Hi Emy,

      PSM II is based on the same concepts, nothing extra. However, questions are much more verbose with many verbose options. Usually, there is no direct answer in the Scrum Guide. Think about the hardest questions from PSM I.

      Definitely, you need to prepare more. Try to read a book from the suggested reading list: https://www.scrum.org/resources/suggested-reading-professional-scrum-master

      Thanks,
      –Mikhail

    Hello Mikhail,

    Thanks to you and the forum. I attempted PSMI again and scored 92.5% this time. The questions this times are simple ones and repetitive of which I got in my first attempt.

      Hi,

      I am very glad you finally did it.
      Keep going!

    Hi Mikhail,

    I have gone through all the questions and answers on this page. While answering you have given reference of scrum.org at some place but many other places you have said, ‘I think’ or ‘to my knowledge’ or you have not given scrum.org reference but still you have answered.

    I understood these Q&A and agree also, BUT the only question in my mind is – if those are correct from PSM 1exam perspective? If we select these answers during the exam, will those be correct so that we will get marks/points in the exam accordingly. Just thought to confirm with you.

    NOTE – I am not pointing anything wrong here or even do not have intention to hurt you. You are doing absolutely great job and it helps a lot.

    1. mlapshin (Post author)

      Hi Ramdas,

      I completely understand your concern. How can the users of my quiz be sure the questions are correct? If you get a similar question in the real exam, will the answer be the same?
      I can easily answer it. I created the quizzes keeping in my mind exactly the same concern. So, every question in my quizzes is backed by a direct quotation from the Scrum Guide. It guarantees the answer is correct.

      Additionally, many people are asking questions at this page. If I can point out the right answer, I do it. When I have any doubts, I share it along with my answer. Also, I am always trying to find the answer in the Scrum Guide and refer to it or explain my thought process.

      Thanks,
      –Mikhail

    I got an interesting question via e-mail:
    ———————–
    Hi Mikhail,
    I wish to review the answer for one of the questions in your free assessment about the formal opportunities to inspect and adapt. The Scrum guide states “Sprint Review” as an “informal meeting” and therefore though an event where you can inspect and adapt, it does not classify as a “formal” opportunity as the question asks for.

    Let me know what you think, thanks!
    ———————–

    I think, it is a very good question because it shows the Scrum Guide contains some little inconsistencies because it is hard to be very precise using a normal spoken language.

    Indeed, the Scrum Guide has: “Sprint Review … is an informal meeting, not a status meeting, and the presentation of the Increment is intended to elicit feedback and foster collaboration.”

    However, the Scrum Guide also contains:
    Scrum prescribes four formal events for inspection and adaptation, as described in the Scrum Events section of this document:
    * Sprint Planning
    * Daily Scrum
    * Sprint Review
    * Sprint Retrospective

    Actually, “informal” in the first quote is about the atmosphere at the Sprint Review. It is a formal event (to inspect and adapt), but everyone should feel free to share an opinion on the Increment and the next steps.

    Thanks,
    –Mikhail

    I got an interesting question about applying Scrum for operations of an Organization:

    Dear Mikhael,

    Hello from Dubai. I recently took a few mock up tests on your website. One of the questions on what Scrum can be used for has an answer option that reads something like “Managing the operations of the organization”. I do not agree with that as I believe managing operations is a continuous process and business as usual and does not deal with the development of a product or service. Therefor I believe that Scrum and even Waterfall cannot be used to manage operations. Please advise if I got this wrong. Would love to hear your thoughts on this.

    Many Thanks

    ——————————–

    My answer is below:

    Hi,

    Indeed, the Scrum Guide contains: “Scrum has been used for … managing the operation of organizations …”.
    I believe, it is not a mere assertion and someone successfully used Scrum for this purpose. However, personally I do not have such experience.

    As far as I know, Scrum is optimized for delivering complex software systems under conditions of uncertainty. Can you split the work into chunks that fit into a Sprint? Would value be maximized by achieving Sprint Goals? Do you have something like Product and Product Owner? Is the team cross-functional and self-organizing?

    Thanks,
    –Mikhail

    Hello Mikhail,

    I have a quick remark about one question on the PSM I LM.
    The question is who is allowed to attend Daily Scrum (multiple choice answer)
    While the correct answer is only the DT, I wonder why the SM isn’t allowed. See, as he is in charge of ensuring the Daily Scrum doesn’t go over 15 minutes and also that the meeting isn’t disrupted, then he is “allowed” to attend the Daily Scrum. Maybe the formulation of the question is strange?
    I’ve been struggling to understand why the SM isn’t allowed, yet he has some action when attending the Daily Scrum.

    Sorry if this is strange, I’m just starting with SM training.

    Thanks!
    Anne

      Hi Anne,

      Take a look here: https://mlapshin.com/index.php/blog/scrum-questions#participate_vs_attend

      The question is based on the difference between “participate” which means come and speak and “attend” which means come and remain silent.
      The SM can come to the meeting, but should remain silent if everything goes fine (only the Dev Team members speak and the meeting is within 15 minutes).

      Thanks,
      –Mikhail

    ….

    Mikhail: I am sorry, I had to delete the question because I see it is copyrighted.

    reddypernati, check my answer for question #9 here: https://mlapshin.com/index.php/blog/scrum-questions/comment-page-15/#comment-1221
    It looks similar to your question that I deleted.

    2. What can the Scrum Value of openness easily impact?
    a. collaboration.b.Software quality C. Employee statisfaction D. Time to market E. Stakeholder trust F.All the above.

    3. Using Scrum ensure adding more resources to a project proportionally increase the value delivered
    True or False

    1. mlapshin (Post author)

      Hi,

      I hope you rephrased the questions.

      1. Which statements about the Sprint Goal is FALSE?
      a. The Product Owner respects the DT opinion on whether they can achieve it.
      B. It is only a forecast and may change within the Sprint as more is learned.
      C. It helps increase focus.
      D. The Scrum Team discusses openly about alternatvie ways to reach it.
      E. If it doesn’t seem achievable, the DT has the courage to tell the PO.
      F. The DT commits to it.

      Mikhail: I see only one such statement:
      B. is FALSE because the Scrum Guide contains: “During the Sprint: No changes are made that would endanger the Sprint Goal;…”

      2. What can the Scrum Value of openness easily impact?
      a. collaboration.b.Software quality C. Employee statisfaction D. Time to market E. Stakeholder trust F.All the above.

      Mikhail:
      F. “All the above.” is the correct option

      3. Using Scrum ensure adding more resources to a project proportionally increase the value delivered
      True or False

      Mikhail:
      I would say False. Scrum only ensures that the most valuable features will be delivered first and the resources will be used optimally.
      However, creation of complex systems is not a linear process. When you have more features to implement and more teams, they will have more dependencies and will have to spend time on resolving them.

      Thanks,
      –Mikhail
