NEW QUESTION # 82
How does Kanban for Scrum Teams maximize value delivered?
(choose the best two answers)
- A. By minimizing time spent in meetings/events.
- B. By choosing higher-value items to deliver.
- C. By optimizing the flow of value.
- D. By minimizing transaction costs.
- E. By enabling tighter empirical feedback loops via faster Cycle Times.
Answer: C,E
Explanation:
Kanban for Scrum Teams maximizes value delivered by:
1.Enabling Tighter Empirical Feedback Loops via Faster Cycle Times (Option B):
Kanban practices help Scrum Teams reduce Cycle Times, which is the time it takes for a work item to move from "start" to "finish." Faster Cycle Times mean that feedback on work done is received more quickly, allowing the team to make necessary adjustments sooner. This rapid feedback loop enhances the empirical process control central to Scrum, thus ensuring that the team is always delivering value in line with the needs of stakeholders(
2.Optimizing the Flow of Value (Option C):
Kanban focuses on optimizing the flow of work through the team's process. This is achieved by limiting Work in Progress (WIP) and actively managing flow metrics such as throughput and cycle time. By optimizing flow, teams can ensure that work items are completed efficiently and effectively, minimizing waste and maximizing the delivery of value to the customer( The other options are less accurate:
*Option A: Minimizing time spent in meetings/events is not the primary goal of Kanban; rather, it is about optimizing flow and value delivery.
*Option D: Minimizing transaction costs is more related to Lean principles, but it does not directly address the value delivered as effectively as options B and C.
*Option E: Choosing higher-value items to deliver is part of prioritization, which is more related to Product Backlog management than to Kanban's specific practices
NEW QUESTION # 83
Which of these statements about Sprints and Kanban is NOT correct?
(choose the best answer)
- A. A Scrum Team will eventually stop using Sprints if they correctly implement Kanban.
- B. The Sprint is an example of limiting Work in Progress (WIP).
- C. The Sprint is an example of a cadence.
- D. The Sprint is an example of an explicit policy for how a team is working.
Answer: A
Explanation:
This statement is incorrect. A Scrum Team will not stop using Sprints just by implementing Kanban. Kanban is used to complement Scrum practices, not replace them. The team continues to use Sprints as a cadence and timebox for delivering increments of work while also incorporating Kanban principles like visualizing work, limiting WIP, and managing flow to enhance their process
NEW QUESTION # 84
True or False: The Sprint length can be thought of as the team's batch size with Scrum Teams using Kanban.
- A. TRUE
- B. Choose only ONE best answer.
- C. FALSE
Answer: C
NEW QUESTION # 85
Work Item Age metrics are most helpful in supporting which of the following? (choose the best two answers)
- A. Inspecting and adapting the team's process and definition of Workflow at the Sprint Retrospective.
- B. Helping the team estimate the size of Work Items.
- C. Inspecting and adapting the Sprint at the Daily Scrum.
- D. Influencing the team's Service Level Expectation (SLE).
- E. Being a leading indicator for the length of the feedback loop for a certain Work Item.
Answer: C,E
NEW QUESTION # 86
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. Cycle Time.
- C. Work in Progress (WIP).
- D. Work Item Age.
- E. Lead Time.
- F. Throughput.
- G. Velocity.
Answer: C,D
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 # 87
True or False: Reduced productivity is the result of optimizing WIP limits.
- A. TRUE
- B. FALSE
Answer: B
NEW QUESTION # 88
True or False: If Scrum is used with Kanban then having a Scrum Master is optional.
- A. False
- B. True
Answer: A
Explanation:
Kanban does not eliminate the need for a Scrum Master when used with Scrum. The Scrum Master remains an essential role to facilitate the Scrum framework, help the team adopt both Scrum and Kanban practices effectively, and ensure the team understands and adheres to Scrum principles.
The role of the Scrum Master includes coaching the team on both Scrum and Kanban practices, removing impediments, and promoting continuous improvement. Therefore, even when Scrum is used with Kanban, the Scrum Master is not optional but a critical role in ensuring that the integration of these practices is successful(
NEW QUESTION # 89
For teams practicing Scrum with Kanban, which of the following can provide the most appropriate metrics for inspecting their flow? (choose the best answer)
- A. Story points and past velocity.
- B. All of the answers.
- C. None of these are Kanban for Scrum Teams metrics.
- D. User stories and t-shirt size.
- E. Control Chart. Cumulative Flow Diagram (CFD) and Aging Work in Progress (Aging Chart).
Answer: E
NEW QUESTION # 90
Which is the best description of probabilistic forecast? (choose the best answer)
- A. A commitment of when a specific scope will be finished.
- B. A forecast based on empirical data as an input on the likelihood of achieving a goal given certain time period.
- C. A formula that calculates a team's future performance.
Answer: B
NEW QUESTION # 91
Work in Progress (WIP) is: (choose the best answer)
- A. The number of PBI's that meet the team's definition of "Ready".
- B. The number of work items started but not finished (according to the Scrum Team's definition of "Workflow").
- C. The total of all items in the Product Backlog.
- D. Equal to the number of PBI's in the Sprint Backlog.
Answer: B
NEW QUESTION # 92
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. Work Item Age.
- C. Lead Time.
- D. Story Points.
- E. Work in Progress.
Answer: E
NEW QUESTION # 93
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. False
- B. True
Answer: A
NEW QUESTION # 94
Within the same Kanban system, Work in Progress (WIP), is NOT a leading indicator for:
(choose the best answer)
- A. Cycle Time.
- B. Number of Product Backlog items finished in a Sprint.
- C. Story points delivered.
- D. Throughput.
Answer: C
Explanation:
Within the same Kanban system, Work in Progress (WIP) is not a leading indicator for "Story points delivered." While WIP can influence throughput and cycle time, it does not directly correlate with story points delivered, as story points are a measure of effort or complexity rather than flow. The number of story points delivered is not directly influenced by the current WIP levels
NEW QUESTION # 95
Which of the following are considered Kanban practices for Scrum Teams? (choose the best answer)
- A. T-shirt size estimation, service level expectations, limiting Work in Progress (WIP).
- B. Visualizing flow, limiting Work in Progress (WIP), actively manage the Work in Progress (WIP), inspecting & adapting the workflow.
- C. Small batch sizes, limiting Work in Progress (WIP), eliminating waste, Kaizen.
- D. Kaizen, removing bottlenecks, policies radiators, pull system.
- E. Class of service, measuring cost of delay, visualizing the workflow, limiting Work in Progress (WIP), managing flow.
Answer: B
NEW QUESTION # 96
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 # 97
A service level expectation (SLE) consists of which two items?
(choose the best two answers)
- A. A cost of delay.
- B. A period of elapsed days.
- C. A forecasted date.
- D. A probability.
Answer: B,D
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 # 98
Work in Progress (WIP) is NOT considered a leading indicator for which of the following measures? (choose the best answer)
- A. Number of Story Points completed.
- B. Number of Product Backlog items finished in a Sprint.
- C. Cycle time.
- D. Throughput.
Answer: A
NEW QUESTION # 99
Which of the following practices is NOT included in Kanban for Scrum Teams? (choose the best answer)
- A. Limiting Work in Progress (WIP).
- B. Actively managing work in progress.
- C. Visualizing the workflow.
- D. Inspecting and adapting the workflow.
- E. Identifying bottlenecks and impediments.
Answer: E
NEW QUESTION # 100
Scrum Teams using Kanban can start to increase predictability by:
(choose the best answer)
- A. Inspecting and adapting the Product Backlog during the Sprint Review.
- B. Reducing the amount of work in progress by introducing Work in Progress (WIP) Limits.
- C. Improving transparency by having a CFD, Control Chart and Aging chart.
- D. Visualizing the Workflow using a Kanban board.
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
