1. A. Defined process.
2. B. Complex process.
3. C. Empiricism.

Which two scenarios would best represent a self-organizing Development Team? (Choose two.)

2. B. Management works with the Scrum Master to optimize the Development Team’s progress during the Sprint.
3. C. Development Team members collaboratively select and re-plan their work throughout the Sprint.
4. D. The Development Team invites external people to the Sprint Planning to help them create a complete and detailed Sprint Backlog.

A self-organized team is a team that is able to self-manage and decide how best to accomplish their work.

A Scrum Team has been working on a product for several iterations and has an average velocity of 55 units of ‘done’ work per Sprint. A second team will be added to work on the same product.
What might be the impact on the original team?

1. A. Their velocity is likely not affected and will remain at 55.
2. B. Their velocity is likely to drop and be less than 55.
3. C. Their velocity is likely to rise and be more than 55.

Correct Answer: B
Similar to membership changes within a single Scrum Team, adding or removing additional Scrum Teams working on the same product will impact productivity in the short term. Adding additional teams often go through recognizable stages as they change from being a collection of strangers to a united group with common goals. Bruce Tuckman's Forming, Storming, Norming, and Performing model describes these stages.

What is a good way for a Scrum Team to ensure that security concerns are addressed and transparent?

3. C. Create a separate backlog for security items and only work on the items when a specialist becomes available.
4. D. Delegate the work to an external team.

Correct Answer: B
The Product Backlog and the Definition of “Done” are artifacts that promote transparency.
