Scrum PSK-I (Professional Scrum with Kanban level I) Examは、ScrumとKanbanフレームワークの知識と理解を検証する認定試験です。Scrumは、複雑な製品の開発に使用される反復的かつ増分的なアジャイルフレームワークであり、Kanbanはワークフローを改善し、開発プロセスの効率を高めるために使用される視覚的な管理ツールです。この試験は、実際のシナリオでScrumとKanbanの原則と実践を適用する能力をテストするために設計されています。
Scrum PSK-Iは、ScrumとKanbanの方法論の統合に焦点を当てた認定試験です。この試験は、ScrumとKanbanがチームのパフォーマンスを向上させ、プロジェクト管理を強化するためにどのように協力できるかを個人の理解を評価するために設計されています。Scrumは、協力、柔軟性、および継続的改善を強調したアジャイルプロジェクト管理のフレームワークです。一方、Kanbanは、作業を視覚化し、進行中の作業を制限し、フローを最適化するリーンの方法論です。
質問 # 15
True or False: Cycle time is considered a lagging indicator.
- A. TRUE
- B. FALSE
正解：A
質問 # 16
In what ways can Work in Progress (WIP) limits help a Scrum Team? (choose the best answer)
- A. All of the answers.
- B. A more sustainable pace.
- C. Provide shorter feedback loops.
- D. Realization of value sooner.
- E. Increased collaboration.
正解：A
質問 # 17
What can a specific work item's Cycle Time metric be used for? (choose the best three answers)
- A. To help the team inspect and adapt their process.
- B. As a leading indicator to the length of feedback loop for that Work Item.
- C. To help the team inspect and adapt their Sprint in the Daily Scrum.
- D. As a lagging indicator to the length of feedback loop for that Work Item.
- E. To influence the team's Service Level Expectation (SLE).
正解：A、D、E
質問 # 18
Which of the following is NOT an essential component to initially achieving flow?
(choose the best answer)
- A. Visualizing your Workflow.
- B. Actively managing WIP.
- C. Limiting Work in Progress (WIP).
- D. Ensuring the Product Backlog is refined frequently.
- E. Inspecting & adapting your Workflow.
正解：D
解説：
While refining the Product Backlog is essential in Scrum, it is not an essential component specifically for achieving flow in Kanban practices. Achieving flow requires visualizing the workflow, limiting WIP, actively managing WIP, and continuously inspecting and adapting the workflow. Frequent Product Backlog refinement helps with the overall Scrum framework but is not directly tied to the initial goal of achieving flow in a Kanban system
質問 # 19
What would be the most opportune time for a Scrum Team to make policy changes to their Work in Progress (WIP) Limits? (choose the best answer)
- A. Anytime during the Sprint.
- B. WIP Limits should not be modified once they have been set.
- C. During the Daily Scrum.
- D. During the Sprint Retrospective.
正解：D
質問 # 20
Why aren't feedback loop practices included in the Kanban Guide for Scrum Teams? (choose the best answer)
- A. Kanban boards are the only feedback loops needed for Scrum Teams using Kanban.
- B. Kanban does not require feedback loops as it focuses on improving productivity. Feedback loops only apply when using Scrumban.
- C. The Kanban Guide for Scrum Teams builds upon the Scrum Guide. There is no need to explicitly add feedback loop practices as they are already in Scrum.
- D. A Scrum Team self-manages and decides what feedback loops are necessary to include in their workflow.
正解：C
質問 # 21
Which of the following helps Scrum Teams, that use Kanban, from exceeding their capacity limits? (choose the best answer)
- A. Managing individual workloads of team members.
- B. Explicit Work In Progress (WIP) Limit policies.
- C. Having daily meetings about work in progress.
- D. Setting a robust Kanban workflow.
正解：B
質問 # 22
Who must change the Work in Progress (WIP) Limits in the Definition of Workflow when urgent work emerges from the Sprint?
(choose the best answer)
- A. No one. WIP Limits cannot be modified during a Sprint.
- B. No one. Urgent work is not a reason to change WIP Limits.
- C. The Product Owner.
- D. The Scrum Master.
- E. The Developers.
正解：B
解説：
In Professional Scrum with Kanban, the Work in Progress (WIP) limits are set as a policy to maintain a sustainable flow of work. Urgent work emerging does not automatically warrant changing these WIP limits; instead, the team should first discuss how to accommodate the urgent work within the existing constraints.
Modifying WIP limits for urgent work could undermine the benefits of a controlled flow, which is why urgent work should not be a reason to change WIP limits during a Sprint
質問 # 23
Is the Scrum Master role needed for Scrum Teams using Kanban? (choose the best answer)
- A. IT DEPENDS
- B. YES
- C. NO
正解：B
質問 # 24
Little's Law is extremely valuable for directly predicting the future since it gives us a measure of what happened in the past? (Choose the best answer)
- A. False - Relying only on your Cycle Time measurements may incorrectly influence you to cut your WIP limits.
- B. True - By understanding our Cycle Time we can use Little's Law to reduce our WIP limits.
正解：A
質問 # 25
What might be considered during the Sprint Retrospective once a team decides to supplement their Scrum with Kanban?
(choose the best answer)
- A. WIP Limit.
- B. All of the answers.
- C. Current policies.
- D. Workflow.
- E. Metrics and charts such as Cumulative Flow Diagram, Cycle Time Scatterplot, and Work Item Aging.
正解：B
解説：
During the Sprint Retrospective, once a team decides to supplement their Scrum with Kanban, all the mentioned elements might be considered:
*Workflow: To ensure it aligns with Kanban practices.
*Current policies: To review and adapt any team policies that may need to change.
*WIP Limit: To set appropriate limits to enhance flow.
*Metrics and charts (e.g., Cumulative Flow Diagram, Cycle Time Scatterplot, Work Item Aging): To visualize flow, identify bottlenecks, and make data-driven decisions for continuous improvement.
Considering all these elements helps the Scrum Team integrate Kanban practices effectively into their existing Scrum framework
質問 # 26
True or False: Reducing WIP limits will always result in decreased productivity.
- A. True
- B. False
正解：B
質問 # 27
True or False: Work Item Age is a leading indicator for the length of the Scrum Team's feedback loop for that (in progress) item.
- A. False
- B. True
正解：B
解説：
Work Item Age is the amount of time a work item has been in progress. It acts as a leading indicator for the length of the Scrum Team's feedback loop for that item. If a work item stays in progress for too long, it indicates that feedback is delayed, potentially impacting the team's ability to adapt and respond effectively.
Tracking Work Item Age helps the team monitor flow and take timely actions to ensure that feedback loops remain short and effective
質問 # 28
What would be the most appropriate reason for a Scrum Team to adjust their Work in Progress (WIP) Limits? (choose the best answer)
- A. When the Developers receive unplanned urgent work during the Sprint.
- B. When the velocity of the Scrum Team velocity becomes too low.
- C. When the work in progress is lower than the capacity of the Developers.
- D. When they want to improve their cycle time, workflow, and focus.
正解：D
質問 # 29
True or False: Kanban can be used to help improve the flow of the Sprint. It can also be used to help improve the flow of work in/out of the Sprint. Regardless, the Kanban Definition of Workflow is owned by the Developers.
- A. True
- B. False
正解：B
質問 # 30
True or False: Reduced productivity is the result of optimizing WIP limits.
- A. FALSE
- B. TRUE
正解：A
質問 # 31

- A. reduce the amount of actual work in process.
- B. make it easier for the Scrum Master to manage the tasks.
- C. increase the utilization rate of the Developers.
- D. allow the team to release multiple times per Sprint.
- E. maximize the amount of actual work in process.
正解：A
