質問 # 28
When can a Work in Progress (WIP) Limit change?
(choose the best answer)

• A. It never changes.
• B. When the Product Owner decides to change it.
• C. At any time.
• D. Only during the Sprint Retrospective.
• E. Only during Sprint Planning.
• F. Only during the Daily Scrum.

正解：D

解説：
According to the Kanban Guide for Scrum Teams, Work in Progress (WIP) limits are set to control the amount of work in progress in a system, enhancing flow, reducing bottlenecks, and ensuring smoother delivery. WIP limits can be changed as a result of an inspection and adaptation cycle, which primarily occurs during the Sprint Retrospective.
During the Sprint Retrospective, the Scrum Team reflects on its process, practices, and interactions. This is the time when the team inspects its flow, evaluates the effectiveness of the current WIP limits, and can make decisions to adjust them based on observed issues or potential improvements. The goal is to optimize the team's ability to deliver value, and adjusting WIP limits during the Retrospective allows for thoughtful consideration based on the team's experience and data from the completed Sprint.
Changing WIP limits at other times could disrupt the flow and reduce the predictability and stability that the limits are intended to create. Therefore, the best practice is to evaluate and change them during the Sprint Retrospective, where the team can inspect the results of their workflow and make informed decisions for the upcoming Sprints

質問 # 29
True or False: The primary purpose of measuring Work Item Age is to identify bottlenecks in the workflow that will need to be addressed.

• A. FALSE
• B. TRUE

正解：A

質問 # 30
According to Little's Law, which of the following statements is true if a team reduces its Work in Progress (WIP) limit? (choose the best two answers)

• A. Average time between starting and finishing (cycle time) of Product Backlog items will likely decrease.
• B. Quality of work completed will likely increase.
• C. Value of each backlog item completed likely will go up.

質問 # 31
Which of the following are leading indicator metrics?
(choose the best two answers)

• A. Cycle Time.
• B. Service Level Expectation.
• C. Work in Progress.
• D. Work Item Aging.
• E. Monte Carlo.

正解：C、D

解説：
Work in Progress (WIP) and Work Item Aging are considered leading indicator metrics in Scrum with Kanban. Leading indicators are metrics that provide information that can help predict future outcomes or performance.
*Work in Progress (WIP): This metric indicates the number of work items currently being worked on and can provide early signals about potential bottlenecks or issues in the workflow. Managing WIP effectively can help teams optimize their flow and predict how work might proceed in the future.
*Work Item Aging: This metric shows how long work items have been in progress without being completed.
It provides an early indication of delays and can help teams identify items that might need attention to maintain a steady flow

質問 # 32
What might be discussed during the Sprint Retrospective if the Scrum Team is considering to use Kanban to complement their Scrum? (choose the best answer)

• A. Metrics and charts such as cumulative flow, scatterplot, and work item aging.

質問 # 37
A Scrum Team's Definition of Workflow must have defined points at which the Scrum Team considers work to have started and to have finished. This allows the team to track their Work in Progress (WIP). How are these points defined?
(choose the best answer)

• A. In any way the Scrum Team chooses to define it.
• B. How it is defined and who within the Scrum Team defines it depends on the boundaries and scope of the Definition of Workflow.
• C. Any refined Product Backlog item in the Product Backlog is WIP.
• D. Any Product Backlog item in the Sprint Backlog is a WIP.
• E. However the Developers want. They have the final say on the Sprint Backlog.

正解：B

解説：
The Definition of Workflow includes the agreed-upon points at which the Scrum Team considers work to have started and finished. These points are determined based on the boundaries and scope of the team's workflow. This definition must be clearly understood by the entire team to track Work in Progress (WIP) effectively and manage flow efficiently. It is up to the Scrum Team to define these boundaries to suit their specific context and workflow needs.

質問 # 38
True or False: If Developers use tasks, then their WIP limits should primarily apply to tasks in the Sprint Backlog.

質問 # 43
True or False: Cycle Time is used as a leading indicator to determine the length of a certain Product Backlog Item's feedback loop. Choose only ONE best answer.

• A. FALSE
• B. TRUE

正解：A

質問 # 44
Sprint Planning mainly leverages Throughput in order to create a forecast for the Sprint Backlog.
Which metric would be most relevant to inspect, during Sprint Planning, if you have some items left over from the previous Sprint?

• A. Work Item Age.
• B. Story Points.
• C. Lead Time.
• D. Cycle Time.
• E. Work in Progress.

正解：E

質問 # 45
For a specific Sprint Backlog item that has been started, what is the best chart (analytic) to determine when it will be finished?
(choose the best answer)

• A. Work Item Aging Chart.
• B. Control chart.
• C. Throughput Run Chart.
• D. Cumulative Flow diagram (CFD).

正解：A

解説：
The Work Item Aging Chart is the best chart to determine when a specific Sprint Backlog item that has been started will be finished. This chart provides a visual representation of how long each work item has been in progress, without being completed. It focuses on items that are currently active and helps teams identify which items are aging too much in the workflow, which might require attention to ensure they are completed promptly. The Work Item Aging Chart helps to quickly identify items that might be taking longer than expected, making it ideal for forecasting when a started item will be finished

質問 # 46
True or False: Reduced productivity is the result of optimizing WIP limits.

• A. FALSE
• B. TRUE

正解：A

質問 # 47
Is the Scrum Master role needed for Scrum Teams using Kanban? (choose the best answer)

正解：B

質問 # 48
What are the benefits of having early, frequent, and consistent feedback loops? (choose the best answer)

• A. Increased customer satisfaction.
• B. Improved workflows.
• C. Identifying and addressing problems early.
• D. All of the above.

正解：D

質問 # 49
Which of these is NOT a good description of Cycle Time?
(choose the best answer)

• A. The time a work item starts until when it finishes.
• B. The time a work item takes from initial idea/concept to feedback returned from customers after a production release.
• C. The length of time a work item stays in one column.
• D. The number of items that move into the delivery/end point per time period (e.g., daily/weekly).

正解：D

解説：
Cycle Time in the context of Professional Scrum with Kanban is defined as the time it takes for a single work item to move from the start to the end of a specific process or workflow. This metric is crucial for understanding how efficiently a team can process individual work items through their defined workflow stages.
*Option A describes a broader measurement from the initial concept to customer feedback post-release. This could align more with the concept of Lead Time rather than Cycle Time.
*Option B correctly describes a possible measurement for Cycle Time - the time a work item spends in one specific column (workflow stage). This is in line with the definitions provided in the Kanban Guide for Scrum Teams, where Cycle Time can measure time within distinct parts of the workflow.
*Option D accurately reflects the definition of Cycle Time, which measures the elapsed time from when work starts on an item until it is completed.
*Option C describes "Throughput," which is a measure of the number of items delivered over a specific time period (e.g., daily or weekly). This is not related to Cycle Time but is a separate flow metric often used alongside Cycle Time to understand team performance and capacity better( Thus, Option C is the correct answer as it does not correctly describe Cycle Time. This explanation is verified with resources from Scrum.org that define Cycle Time within the scope of Professional Scrum with Kanban practices.
