NEW QUESTION # 40
What does the Work Item Aging chart show? (Choose the best answer)
- A. For each item on the Kanban board how long ago has it been pulled into WIP.
- B. The approximate average age of work in process in the team.
- C. How many sprints ago has the team revised their WIP limits.
- D. How many days has the team worked without breaching the WIP limits.
Answer: A
NEW QUESTION # 41
A service level expectation (SLE) consists of which two items?
(choose the best two answers)
- A. A period of elapsed days.
- B. A forecasted date.
- C. A probability.
- D. A cost of delay.
Answer: A,C
Explanation:
A Service Level Expectation (SLE) in Kanban provides an agreement or expectation regarding the time it will take to complete a work item. An SLE consists of two main elements:
1. A probability (Option B): This is the likelihood or confidence level (e.g., 85%) that a work item will be completed within the specified period.
2. A period of elapsed days (Option D): This defines the maximum amount of time (e.g., 10 days) expected for a work item to be completed. The combination of these two elements helps set clear expectations and guide planning and forecasting efforts( Options A (A cost of delay) and C (A forecasted date) are not part of the standard elements defining an SLE. The cost of delay is a concept related to prioritization, and a forecasted date is usually derived from the SLE but is not part of it.
NEW QUESTION # 42
Which of the following metrics are likely to be reviewed during flow-based Daily Scrum?
(choose the best two answers)
- A. Process control chart and Scrum Team's 85th percentile.
- B. Throughput.
- C. Work in Progress (WIP).
- D. Cycle Time.
- E. Velocity.
- F. Work Item Age.
- G. Lead Time.
Answer: C,F
Explanation:
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
NEW QUESTION # 43
A cumulative flow diagram can show you:
(Choose the best two answers)
- A. The average Throughput for a specific date range.
- B. The exact average Cycle Time for all items completed on a specific date.
- C. The Cycle Time for an item that completed on a specific date.
- D. The total amount of Work in Progress (WIP) for a specific date.
Answer: C,D
Explanation:
A cumulative flow diagram (CFD) provides insights into the amount of WIP and helps track Cycle Time by showing how long items stay in each stage of the workflow. This visualization tool is valuable for teams using Scrum with Kanban as it highlights bottlenecks and helps manage flow through the stages of the workflow.
References: The Kanban Guide for Scrum Teams.
NEW QUESTION # 44
Which of the following is the best use of a Work Item Age chart? (Choose the best answer)

NEW QUESTION # 46
True or False: The Sprint length can be thought of as the team's batch size with Scrum Teams using Kanban.
- A. FALSE
- B. TRUE
- C. Choose only ONE best answer.
Answer: A
NEW QUESTION # 47
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 # 48
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
Answer: B
NEW QUESTION # 49
What is the best chart to determine when a single item that has not been started will be finished?
(choose the best answer)
- A. Throughput run chart.
- B. WIP Aging chart.
- C. Cycle Time scatterplot.
- D. Cumulative Flow diagram (CFD).
Answer: C
Explanation:
A Cycle Time scatterplot is the best chart to determine when a single item that has not been started will be finished. This chart shows the distribution of cycle times for completed work items. By analyzing the historical data, you can estimate the likely cycle time for a new item.
Here's how to use the Cycle Time scatterplot:
* Identify the average cycle time:Calculate the average cycle time for similar types of work items.
* Consider variability:Look at the range of cycle times to understand the variability in delivery times.
* Estimate completion time:Based on the average cycle time and variability, estimate when the new item is likely to be completed.
While the other charts (CFD, Throughput run chart, and WIP Aging chart) provide valuable insights into the overall workflow, they are not as effective for predicting the completion time of a single item.
NEW QUESTION # 50
True or False: If Developers use tasks, then their WIP limits should primarily apply to tasks in the Sprint Backlog.
- A. True
- B. False
Answer: B
NEW QUESTION # 51
What are the four key flow metrics in Scrum with Kanban?
(choose the best answer)
- A. Work in Progress (WIP), Velocity, Lead Time, Cycle Time.
- B. Throughput, Work in Progress (WIP), Velocity, Lead Time.
- C. Work in Progress (WIP), Work Item Age, Throughput, Cycle Time.
- D. Velocity, Lead Time, Cycle Time, Cost.
Answer: C
Explanation:
The four key flow metrics in Scrum with Kanban are:
* Work in Progress (WIP): The number of items that are currently being worked on.
* Work Item Age: The time that has elapsed since an item started, which helps identify aging work that may need attention.
* Throughput: The number of items completed over a specific period, helping to measure productivity.
* Cycle Time: The total time from when an item starts until it is finished, used to assess how quickly items are moving through the process.
These metrics are essential for understanding and optimizing the flow of work in a Scrum team using Kanban practices
NEW QUESTION # 52
Why aren't feedback loop practices included in the Kanban Guide for Scrum Teams? (choose the best answer)
- A. Kanban does not require feedback loops as it focuses on improving productivity. Feedback loops only apply when using Scrumban.
- B. Kanban boards are the only feedback loops needed for Scrum Teams using Kanban.
- 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.
Answer: C
NEW QUESTION # 53
True or False: Little's Law is used to forecast a Scrum Team's output.
- A. True
- B. False
Answer: B
Explanation:
Little's Law is a formula used to understand the relationship between system throughput, work-in-progress (WIP), and lead time. While it can be used to analyze and optimize the flow of work, it is not specifically designed for forecasting a Scrum Team's output.
Scrum Teams typically use techniques like story point estimation and historical velocity to forecast their output.
NEW QUESTION # 54
Which metric makes most sense to look at during Sprint Planning?
(choose the best answer)
- A. Work Item Aging.
- B. Service Level Expectation.
- C. Throughput.
- D. Work in Progress.
Answer: C
Explanation:
During Sprint Planning, the most relevant metric to consider is Throughput (Option B), which measures the number of work items completed in a given time frame (e.g., per Sprint). By reviewing past throughput, the team can make informed decisions about how much work they are likely to complete in the upcoming Sprint, taking into account their capacity and any potential changes in team composition or external factors.
*Service Level Expectation (A) is less relevant as it is more about setting expectations with stakeholders rather than planning the Sprint.
*Work Item Aging (C) is a leading indicator metric used to track how long current work items have been in progress, which is less helpful during planning.
*Work in Progress (D) indicates the current workload but does not provide historical data useful for forecasting in Sprint Planning
NEW QUESTION # 55
Scrum Teams using Kanban can start to increase predictability by:
- A. Visualizing the Workflow using a Kanban board.
- B. Improving transparency by having a CFD: Control Chart and Aging chart.
- C. Reducing the amount of work in progress by introducing Work in Progress (WIP) Limits.
- D. Inspecting and adapting the Product Backlog during the Sprint Review.
Answer: C
Explanation:
By limiting WIP, Scrum Teams using Kanban create a more predictable flow, as it prevents the team from overcommitting and encourages them to finish work items before starting new ones. This aligns with Kanban' s principle of optimizing flow and Scrum's iterative delivery approach. References: The Kanban Guide for Scrum Teams.
NEW QUESTION # 56
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. True
- B. False
Answer: A
NEW QUESTION # 57
A Service Level Expectation (SLE) consists of which two items?
(Choose the best two answers)
- A. A period of elapsed days.
- B. A forecasted date.
- C. A probability.
- D. A cost of delay.
Answer: A,C
Explanation:
An SLE combines a timeframe (elapsed days) and a probability, representing the likelihood that a work item will be completed within that timeframe. This helps to set realistic expectations for stakeholders and guide the team in maintaining a predictable flow. References: The Kanban Guide for Scrum Teams.
NEW QUESTION # 58
Workflow can be thought of as the Scrum Team's policy for which of the following? (choose the best answer)
- A. How to get work done.
- B. Defining when development is complete and validation begins.
- C. How to increase the Team's WIP limit.
- D. What completed work looks like.
Answer: A
