Question #33
What can occur if you were to reduce batch sizes? (Choose all that apply)
- A . Improved efficiency due to faster feedback loops.
- B . Higher motivation due to seeing your work get done and deliver value earlier.
- C . Lower efficiency due to overhead / transaction costs in case the batch size is too small.
- D . Highlight a need to work to improve processes/infrastructure to reduce the pain of frequent costly overhead.
Correct Answer: A,B,C,D
A,B,C,D
Explanation:
Reducing batch sizes is a powerful lever with many potential effects. Finding the right batch size requires inspection and adaptation by the Scrum Team based on seeing their flow in action and the effect on different soft and hard metrics.

Question #34
Which two items would you expect to see in a service level expectation (SLE)? (choose the best two answers)
- A . A probability
- B . A period off elapsed day
- C . A forecasted date
- D . A cost of engineering
Correct Answer: A,B
A,B
Explanation:
An SLE forecasts how long it should take a given item to flow from start to finish within your workflow. The SLE itself has two parts: a period of elapsed days and a probability associated with that period (e.g., "85% of work items will be finished in 8 days or less" which can also be stated as "8 days with 85% confidence/probability").

Question #35
What can a specific work item’s Cycle Time metric be used for? (choose the best three answers)
- A . To influence the team’s Service Level Expectation (SLE).
- B . To help the team inspect and adapt their process.
- C . As a leading indicator to the length of feedback loop for that Work Item.
- D . As a lagging indicator to the length of feedback loop for that Work Item.
- E . To help the team inspect and adapt their Sprint in the Daily Scrum.
Correct Answer: A,B,D
A,B,D
Explanation:
Cycle time metric is a lagging indicator of flow. It is available only after an item is actually finished from the workflow perspective (e.g. reached a Done lane on the Kanban board). It is typically used to drive improvement work as well as to be able to establish internal/external expectations as to the team’s turnaround time on specific items.
WIP and Work Item Age are leading indicators for the length of feedback loop of a Work Item and inspecting and adaptation of the Sprint at the Daily Scrum.

Question #36
When using Kanban in Scrum, a team needs to use which of the following four metrics of flow? (choose the best four answers)
- A . Cycle Time
- B . Work in Progress (WIP)
- C . Work Item Age
- D . Cumulative Flow Diagram (CFD)
- E . Lead Time
- F . Throughput
Correct Answer: A,B,C,F
A,B,C,F
Explanation:
The four basic metrics of flow that Scrum Teams using Kanban need to track are as follows:
Work in Progress (WIP): The number of work items started but not finished.
Cycle Time: The amount of elapsed time between when a work item starts and when a work item finishes.
Work Item Age: The amount of time between when a work item started and the current time. This applies only to items that are still in progress.
Throughput: The number of work items finished per unit of time.

Throughput: The number of work items finished per unit of time.
Question #37
Work Item Age metrics are most helpful in supporting which of the following? (choose the best two answers)
- A . Inspecting and adapting the Sprint at the Daily Scrum.
- B . Inspecting and adapting the team’s process and definition of Workflow at the Sprint Retrospective.
- C . Influencing the team’s Service Level Expectation (SLE).
- D . Helping the team estimate the size of Work Items.
- E . Being a leading indicator for the length of the feedback loop for a certain Work Item.
Correct Answer: A,E
A,E
Explanation:
Work Item Age is a leading indicator for what a team’s cycle time (i.e. the length of the feedback loop) is likely to be for a certain item.
It is also a leading indicator to determine when an item, that is in progress, is likely to be ‘finished’ in
order for the team to adapt their Sprint.

Question #38
Which of the following is TRUE about the relationship between Sprints and Kanban for Scrum? (choose the best three answers)
- A . Sprints are examples of cycles and cadence.
- B . Sprints are examples of a policy that shows the team’s way of working.
- C . It is easier to achieve Sprint objectives when applying Kanban practices.
- D . A Sprint is an example of limiting Work in Progress (WIP).
Correct Answer: A,B,D
A,B,D
Explanation:
The Kanban complementary practices don’t replace Scrum’s Sprint. The Scrum Framework has built in components that are the starting point (foundation) for Kanban practices to enhance and expand. The Sprint is still a cadence or a regular heartbeat for inspection and adaptation of both product and process. Teams using Scrum with Kanban use the Sprint events as a feedback improvement loop by collaboratively inspecting and adapting their definition of "Workflow" and flow metrics.

Question #39
Kanban can help enhance visibility for: (choose the best three answers)
- A . The Definition of Done.
- B . The Sprint Backlog.
- C . The Product Backlog.
- D . The Sprint Retrospective.
Correct Answer: A,B,C
A,B,C
Explanation:
One of the keys to effective visualization for a Scrum Team is to make sure it sees the flow of Product Backlog items from the Product Backlog (idea identification, through refinement, analysis), Sprint Backlog (design, coding, testing, and deployment); all the way to "Done" (Definition of Done).
