Workflow can be thought of as the Scrum Team’s policy for which of the following? (choose the best answer)
- A . Defining when development is complete and validation begins.
- B . How to get work done.
- C . How to increase the Team’s WIP limit.
- D . What completed work looks like.
B
Explanation:
This is similar to how the Definition of Done can be considered the team’s policies for what done looks like.
Reducing batch sizes might have the following impact: (choose all that apply)
- A . Highlight a need to improve processes/infrastructure to reduce the pain of frequent costly overhead.
- B . Improving efficiency due to faster feedback loops.
- C . Lower efficiency due to overhead/transaction costs in case the batch size is too small.
- D . Higher motivation due to seeing your work get done and deliver value earlier.
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.
Which of these metrics is most valuable for Sprint Planning? (Choose the best answer)
- A . Throughput.
- B . Points Delivered.
- C . Work Item Age.
- D . Cycle time.
A
Explanation:
When planning a Sprint, our main interest is to figure out how many backlog items to pull into the Sprint. Throughput of previous Sprints is the most useful metric for figuring this out. An advanced technique would be to use a Monte Carlo simulation which leverages the Scrum Team’s Throughput data in order to forecast the probabilities (or confidence levels) for completing various amounts of items in a Sprint.
True or False: When using Scrum with Kanban you can release multiple times during the Sprint.
- A . True
- B . False
A
Explanation:
Scrum says you can release as often as you want during the Sprint. Bringing Kanban into the picture does not change this. Kanban actually helps bring to light the potential and value of reducing batch sizes, e.g. for releasing and driving Scrum Teams to consider releasing more often during the Sprint.
True or False: Scrum Events, Scrum Team Accountabilities, and Scrum Artifacts are changed when using Scrum with Kanban. For example, the Scrum Team might choose to omit the Sprint Retrospective when using Kanban with Scrum.
- A . True
- B . False
B
Explanation:
Adding Kanban to Scrum provides a technique to help the Scrum Team focus on driving a continuous flow of activity, but does not negate value provided by the Scrum Events, Artifacts, and Accountabilities.
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
B
Explanation:
Cycle Time is a lagging indicator – you only know the Cycle Time after the PBI reached the end of the team’s Definition of Workflow. A Service Level Expectation (SLE) is based on Cycle Time scatter plot percentile lines.
True or False: A Service Level Expectation (SLE) target reflects the Scrum Team’s aspirations toward a reliable cycle time.
- A . True
- B . False
A
Explanation:
Regardless of whether it is based on historical data or not, a Service Level Expectation (SLE) indeed is an expectation the team sets for themselves. It should be aspirational yet realistic and reliable. Aspiring and then missing most of the time is not what an SLE is about.

True or False: Reducing WIP limits will always result in decreased productivity.
- A . True
- B . False
B
Explanation:
WIP limits help create focus by reducing context-switching, thus a lower WIP limit can result in higher productivity.
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
A
Explanation:
If an item is aging quite a bit it is certainly an indication that its Cycle Time will be high. Cycle Time throughout the Scrum Team’s definition of Workflow can also be considered the length of the team’s feedback loop.
True or False: Scrum Events, Scrum Team Accountabilities, and Scrum Artifacts are augmented when using Scrum with Kanban. For example, having a clear indicator of the age of active Sprint Backlog items may help the Scrum Team during the Daily Scrum, helping them to better Inspect and Adapt their daily work.
- A . True
- B . False
A
Explanation:
Adding Kanban to Scrum provides a technique to help the Scrum Team focus on driving a continuous flow of activity but does not negate value provided by the Scrum Events, Scrum Artifacts, and Scrum Team Accountabilities. However, flow-based metrics/charts & forecasts may get added to Scrum Events as per the Kanban Guide for Scrum Teams.
