質問 # 13
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. Value of each backlog item completed likely will go up.
- B. Quality of work completed will likely increase.
- C. In a given time period, the average number of Product Backlog items (throughput) completed will likely increase.
- D. Average time between starting and finishing (cycle time) of Product Backlog items will likely decrease.
正解：C、D
質問 # 14
When the Developers limit Work in Progress (WIP) inside a Sprint, what would you expect to observe?
(Choose the best three answers)
- A. Increased collaboration/swarming between the Developers.
- B. The Developers would stop beginning work, and instead, start finishing work.
- C. The amount of work done by the end of the Sprint would be reduced.
- D. Self-management would be strengthened as a result of increased transparency.
正解：A、B、D
解説：
When WIP limits are implemented, Developers are encouraged to focus on completing existing tasks rather than starting new ones. This leads to a more collaborative approach, as team members may swarm to complete items together. Additionally, limiting WIP enhances transparency in the process, which in turn strengthens self-management by the team. These principles align with Kanban's emphasis on active management and the Scrum framework's focus on collaboration. References: The Kanban Guide for Scrum Teams.
質問 # 15
What might a Scrum Team visualize with Kanban?
(choose the best three answers)
- A. The Sprint Backlog.
- B. The Sprint Retrospective.
- C. The Product Backlog.
- D. The Definition of Done.
正解：A、C、D
解説：
When a Scrum Team uses Kanban, they can visualize:
*The Product Backlog: By making the Product Backlog visible, the team can track what work items are upcoming and prioritize them effectively.
*The Sprint Backlog: Visualizing the Sprint Backlog helps the team see the work planned for the current Sprint, track progress, and manage flow.
*The Definition of Done: Making the Definition of Done visible ensures that all team members and stakeholders understand the criteria that must be met for work to be considered complete
質問 # 16
Which of the following statements about supplementing Scrum with Kanban practices is true?
(choose the best answer)
- A. Scrum Teams may choose to skip the Sprint Planning event.
- B. It implies that the Scrum Team must have a sequential approach to work.
- C. It encourages team collaboration/swarming.
- D. It applies primarily to maintenance type of work.
正解：C
解説：
Supplementing Scrum with Kanban practices encourages team collaboration and swarming. Kanban practices such as visualizing the workflow, limiting WIP, and focusing on flow metrics foster an environment where team members are more likely to collaborate closely to resolve bottlenecks and ensure a steady flow of work.
This collaboration, often called "swarming," involves team members working together on fewer items to complete them faster, thereby enhancing team dynamics and efficiency
質問 # 17
Which of these statements about Sprints and Kanban is NOT correct?
- A. A Scrum Team will eventually stop using Sprints if they correctly implement Kanban.
- B. The Sprint is an example of an explicit policy for how a team is working.
- C. The Sprint is an example of limiting Work in Progress (WIP).
- D. The Sprint is an example of a cadence.
正解：A
解説：
Sprints remain a core aspect of the Scrum framework, regardless of the use of Kanban. Sprints provide a time-boxed cadence and structure that is integral to Scrum. The addition of Kanban practices enhances Scrum but does not replace the need for Sprints. Reference: The Kanban Guide for Scrum Teams.
質問 # 18
The Scrum Team's Definition of Workflow includes descriptions of each state of a work item can be. True or False: The various states of a work item described in the Definition of Workflow can only encompass flow inside of the Sprint. ie limited to the state of each column on the Developers' Kanban board.
- A. TRUE
- B. FALSE
正解：B
質問 # 19
The basic metrics of flow that Scrum Teams using Kanban will need to track are: (choose the four best answers)
- A. Cycle Time
- B. Lead Time
- C. Velocity
- D. Throughput
- E. Work in Progress (WIP)
- F. Work Item Age
正解：A、D、E、F
質問 # 20
Which of these are LEAST likely to be included in the definition of "Workflow" policies? (choose the best three answers)
- A. A Gantt chart.
- B. WIP Limits.
- C. Service Level Expectations.
- D. Definition of Done.
- E. Work Item types.
- F. The Increment.
- G. A Burndown chart.
- H. Pull/prioritization policies.
- I. Visualization policies.
正解：A、F、G
質問 # 21
True or False: Limiting Work in Progress (WIP) will likely reduce the amount of collaboration in the Scrum Team.
- A. True
- B. False
正解：B
解説：
Limiting Work in Progress (WIP) is likely to increase rather than reduce collaboration within a Scrum Team.
When WIP limits are enforced, team members are encouraged to "swarm" around fewer tasks, focusing on completing them together rather than starting new work. This promotes more collaborative behaviors, such as pairing or mob programming, to get work items done efficiently
質問 # 22
True or False: Little's Law is used to forecast a Scrum Team's output.
- A. False
- B. True
正解：B
解説：
Little's Law is a mathematical formula used in queueing theory and Kanban to relate the average number of items in a system (Work in Progress), the average completion rate (Throughput), and the average time an item spends in the system (Cycle Time). In the context of Scrum Teams using Kanban, Little's Law can be used to forecast a team's output by understanding the relationship between these variables( Thus, it is True that Little's Law can be used to forecast a Scrum Team's output, assuming that the underlying assumptions of Little's Law (such as a stable system and consistent flow) are met.
質問 # 23
True or False: Releases are limited to the end of the Sprint cycle when Scrum Teams use Kanban.
- A. TRUE
- B. FALSE
正解：B
質問 # 24
Which of these statements are true about Kanban and the Scrum theory of empiricism?
(choose the best two answers)
- A. The Kanban board provides Scrum Teams with transparency that helps them inspect and adapt their process.
- B. Kanban metrics are used in the Sprint Review to allow the Product Owner to inspect the Throughput and adapt the Scrum Team's Cycle Time.
- C. Kanban helps Scrum Teams achieve faster, healthier flow. That brings more rapid transparency about the product, enabling a more effective inspection and
- D. Kanban helps Scrum Teams deal with simple and complicated work where empiricism is not necessary.
正解：A、C
解説：
adaptation loop.
Explanation:
1. The Kanban Board Provides Transparency (Option A):
A Kanban board visualizes the flow of work, making it easy for the Scrum Team to see the status of work items, identify bottlenecks, and inspect and adapt their processes. This visual transparency is a fundamental aspect of both Scrum and Kanban and supports the empirical process control central to Scrum(
2. Kanban Helps Achieve Faster, Healthier Flow (Option D):
By focusing on optimizing flow (e.g., reducing Cycle Time and managing Work in Progress), Kanban helps Scrum Teams achieve a faster, more predictable flow of work. This improvement in flow brings more rapid transparency, allowing for more effective inspection and adaptation during Scrum events such as the Daily Scrum, Sprint Review, and Sprint Retrospective( Option B (Kanban metrics are used in the Sprint Review to allow the Product Owner to inspect Throughput and adapt the Scrum Team's Cycle Time) is not necessarily accurate, as the Sprint Review focuses on the product increment and stakeholder feedback, not directly on Kanban metrics.
Option C (Kanban helps Scrum Teams deal with simple and complicated work where empiricism is not necessary) is incorrect because both Kanban and Scrum rely on empiricism (transparency, inspection, and adaptation) to deal with work complexity
質問 # 25
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 # 26
True or False: Using a flow-based perspective can enhance the Scrum events.
- A. TRUE
- B. FALSE
正解：A
質問 # 27
True or False: In a flow-based system, the number of tasks is not necessarily limited, rather the amount of value-generating work items is limited.
- A. False
- B. True
正解：B
質問 # 28
True or False: Cycle Time is a direct leading indicator for the length of the Scrum Team's feedback loop for a Product Backlog item.
- A. True
- B. False
正解：B
質問 # 29
True or False: Work in Progress (WIP) Limits should primarily apply to tasks related to an individual Product Backlog item in the Sprint Backlog.
- A. TRUE
- B. FALSE
正解：B
質問 # 30
Which of the following metrics are likely to be reviewed during flow-based Daily Scrum?
(choose the best two answers)
- A. Velocity.
- B. Process control chart and Scrum Team's 85th percentile.
- C. Work Item Age.
- D. Throughput.
- E. Work in Progress (WIP).
- F. Cycle Time.
- G. Lead Time.
正解：C、E
解説：
During a flow-based Daily Scrum, the team is likely to review metrics such as Work Item Age and Work in Progress (WIP):
*Work Item Age: Helps to identify items that have been in progress for a longer time than expected, signaling possible impediments or the need for swarming to complete those items.
*Work in Progress (WIP): Indicates the number of items currently being worked on, ensuring that the team is not exceeding the agreed WIP limits, which is crucial for maintaining a steady flow
質問 # 31
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
