NEW QUESTION # 78
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. Any Product Backlog item in the Sprint Backlog is a WIP.
- C. Any refined Product Backlog item in the Product Backlog is WIP.
- D. However the Developers want. They have the final say on the Sprint Backlog.
- E. How it is defined and who within the Scrum Team defines it depends on the boundaries and scope of the Definition of Workflow.
Answer: E
Explanation:
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.
NEW QUESTION # 79
True or False: If you reduce your batch size, your overall efficiency will always increase.
- A. True
- B. False
Answer: B
Explanation:
Reducing batch size does not always guarantee an increase in overall efficiency. While smaller batch sizes can lead to faster feedback, more frequent deliveries, and reduced risk, there can be situations where reducing the batch size too much results in inefficiencies, such as increased overhead costs or excessive context switching. Thus, the relationship between batch size and efficiency depends on the context, system constraints, and the nature of the work

- A. In a given time period, the average number of Product Backlog items (throughput) completed will likely increase.
- B. Average time between starting and finishing (cycle time) of Product Backlog items will likely decrease.
- C. Quality of work completed will likely increase.
- D. Value of each backlog item completed likely will go up.
Answer: A,B
NEW QUESTION # 81
In the middle of a Sprint, a Product Owner has requested the Developers to add a new urgent item to their Sprint Backlog. The team is currently at their WIP Limit.
Which would be the two most appropriate responses? (choose the two best answers)
- A. Adjust the WIP Limits to allow for taking on the extra item and update their definition of Workflow.
- B. Take on the urgent item as an exception to the WIP Limits, pushing this item along on top of the existing flow and note a WIP exception.
- C. Reject the urgent item because the WIP Limits do not allow it. Tell the Product Owner to wait until the next Sprint.
- D. Add the urgent item to their Sprint Backlog but only start working on that new item when enough room frees up.
Answer: B,D
NEW QUESTION # 82
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. True
- B. False
Answer: A
NEW QUESTION # 83
True or False: Product Backlog refinement can be included in the team's Workflow description.
- A. FALSE
- B. TRUE
Answer: B
NEW QUESTION # 84
Little's Law states that:
(choose the best answer)
- A. Average Cycle Time = Average Work in Progress / Average Throughput.
- B. Average Throughput = Average Cycle Time * Average Work in Progress.
- C. Average Throughput = Average Cycle Time / Average Work in Progress.
- D. Average Work in Progress = Average Cycle Time / Average Throughput.
Answer: A
Explanation:
Little's Law states:
*Average Cycle Time = Average Work in Progress (WIP) / Average Throughput.
Little's Law is used to understand and forecast the performance of a workflow system. It implies that if you know two of these three variables (Cycle Time, WIP, Throughput), you can calculate the third. The correct formula is Option A( Options B, C, and D do not correctly state Little's Law.
NEW QUESTION # 85
True or False: Cycle time is considered a lagging indicator.
- A. FALSE
- B. TRUE
Answer: B
NEW QUESTION # 86
True or False: The Scrum Framework contains elements that can be treated as explicit policies.
- A. True
- B. False
Answer: A
Explanation:
The Scrum framework contains elements that can be treated as explicit policies. For example, Scrum defines specific roles, events, and artifacts, which are treated as rules or guidelines that the team must follow to maintain Scrum's framework. In the context of Scrum with Kanban, additional explicit policies, such as Work in Progress (WIP) limits, may also be established to further optimize flow
NEW QUESTION # 87
A Cycle Time Scatterplot can help you visualize: (choose the best answer)
- A. Groups of Cycle Time outliers.
- B. Individual Cycle Time outliers.
- C. All of the answers.
- D. General Cycle Time trends.
Answer: C
NEW QUESTION # 88
True or False: A team's future performance can be determined by using Little's Law. (Choose the best answer)
- A. FALSE
- B. TRUE
Answer: A
NEW QUESTION # 89
True or False: A Scrum Team's workflow is the team's "policy" for how items move through different states towards 'done'.
- A. FALSE
- B. TRUE
Answer: B
NEW QUESTION # 90
Which of the following will a Scrum Team most likely use as an input to Sprint Planning? (choose the best answer)
- A. Service Level Expectation (SLE).
- B. Work in Progress (WIP).
- C. Work Item Age.
- D. Throughput.
Answer: D
NEW QUESTION # 91
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. Cycle Time.
- B. Story Points.
- C. Work Item Age.
- D. Lead Time.
- E. Work in Progress.
Answer: E
NEW QUESTION # 92
When can a Work in Progress (WIP) Limit change?
(choose the best answer)
- A. At any time.
- B. Only during Sprint Planning.
- C. Only during the Sprint Retrospective.
- D. It never changes.
- E. When the Product Owner decides to change it.
- F. Only during the Daily Scrum.
Answer: C
Explanation:
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
NEW QUESTION # 93
True or False: Little's Law is used to forecast a Scrum Team's output.
- A. True
- B. False
Answer: A
Explanation:
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.
NEW QUESTION # 94
True or False: The Scrum Team's aim for predictable cycle time can seen by the Service Level Expectations (SLE) that they set to themselves.
- A. FALSE
- B. TRUE
Answer: B
NEW QUESTION # 95
True or False: Reduced productivity is the result of optimizing WIP limits.
- A. FALSE
- B. TRUE
Answer: A
NEW QUESTION # 96
Scrum Teams using Kanban can start to increase predictability by:
(choose the best answer)
- A. Improving transparency by having a CFD, Control Chart and Aging chart.
- B. Reducing the amount of work in progress by introducing Work in Progress (WIP) Limits.
- C. Visualizing the Workflow using a Kanban board.
- D. Inspecting and adapting the Product Backlog during the Sprint Review.
Answer: B
Explanation:
Scrum Teams using Kanban can start to increase predictability by reducing the amount of work in progress (WIP) through WIP limits. This approach helps to limit the number of items being worked on at any given time, thus reducing multitasking and context switching. It allows the team to focus on completing a few items before starting new ones, which directly impacts the flow of work and helps to predict when items will be completed. By controlling the WIP, teams can achieve a steady flow of work, improve cycle times, and make more reliable forecasts about future deliveries
