Scrum PSM-II Test Passed : Professional Scrum Master level II (PSM II)

Over the course of several Sprints, the relationship between the Product Owner and the Development team has suffered. The Development Team is upset with the Product Owner for the constantly changing the upcoming items for the product. The Product Owner is upset with the Development Team for changing the work that needs to be done during the Sprint.
What should Steven, the Scrum Master, do?

• A. The Scrum Master's responsibility is to ensure the Development Team has a stable velocity. Any changes that negatively impact the team's velocity will be rejected by the Scrum Master.
• B. During the Sprint Retrospective, ask the Product Owner and the Development Team to address the issues. Have the Team discuss why the changes occur and what impact they have on the value of the product.
• C. Take the time between Sprints to organize a team building session to rebuild the relationship.
• D. Explain to the Development Team that the Product Owner is accountable for flow of value and needs to be followed in order to maximize the value delivered.

You are the Scrum Master for four Scrum Teams working from the same Product Backlog.
Several of the Developers come to you complaining that work identified for the upcoming two Sprints will require full time commitment from Stella, an external specialist who is not a member of any of the four Scrum Teams. What would you consider acceptable solutions for the problem?
(Choose the best three answers)

• A. Ask Stella for a plan to hire and train additional people in her domain, and in the meantime work with the Product Owner and Scrum Teams to re-prioritize the work so that tasks not depending on Stella can be done first
• B. Create a team with Stella and identify people from the Scrum Teams to temporarily work in Stella's domain to learn to better serve the existing teams
• C. Developers with an interest in Stella's domain could volunteer to take on this work in their respective Scrum Teams.
• D. Investigate whether additional techniques or frameworks for scaling Scrum would be appropriate for these Scrum Teams.
• E. Merge the Scrum Teams into one large Scrum Team for the next two Sprints. When the need for Stella's expertise is over, the teams can separate again
• F. Have the Developers re-order the Product Backlog so Stella can serve one team full-time in a Sprint
• G. Organize a release Sprint in which Stella can thoroughly check and complete all the work done in her domain before considering the work releasable.

What are typical Product Owner activities during Sprint 0?

• A. Ensuring there is enough work to do for at least three Sprints.
• B. Allocating enough resources before starting Sprint 1.
• C. Creating a project plan based on the defined timeline.
• D. Creating User Stories based on the requirements document.
• E. There is no such thing as Sprint.

Your company has notified the stakeholders that they will be delivering the first release of a new product within ten Sprints. On the seventh Sprint, the Scrum Team discovers that they will not be able to include all of the expected features within the first release. The Product Owner believes if they remove some items from the Definition of Done they will be able to accelerate the development process. The Development Team objects to this idea as it will lead to technical debt.
As a Scrum Master, what would be the best two ways to explain to the Product Owner the impact of technical debt? (Choose two.)

• A. Reducing the Definition of Done will introduce unknown errors as development progresses and functionality is added. The system can become more difficult to stabilize as work progresses.
  Development for the actual release as well as future releases will be slowed down in unpredictable ways.
• B. Releasing the version upon a reduced Definition of Done creates false assumptions about the actual state of the system. This will create many interruptions during the development of the next release as fixes will need to be done to the previous release caused from a reduction of quality.
• C. The amount of technical debt will need to be analyzed in order to understand the impact on subsequent releases in order to allocate additional Sprints at the end of the project.
• D. As long as there is still technical debt in the current release, feature development for the next release cannot be started. The Product Owner must first agree to this impact before allowing changes to the Definition of Done.

What must the Development Team do during the first Sprint?

• A. Create a potentially shippable product Increment that includes at least one piece of functionality.
• B. Analyze and estimate the requirements for the subsequent Sprints.
• C. Only design and develop the architecture and infrastructure.
• D. Create a project plan in order to map functional development to Sprint dates.
