Scrum Questions

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

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.

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:

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. All the other options are Scrum Events. Any event in Scrum is an opportunity to inspect and adapt. Sprint is not an event. It is just a time frame.
