Question 1 Selectable Answer

A Cycle Time Scatterplot can help you visualize: (choose the best answer)

A. General Cycle Time trends.
B. Individual Cycle Time outliers.
C. Groups of Cycle Time outliers.
D. All of the answers.

Answer:
Explanation:
The main chart/report used to visualize and analyze Cycle Times is the Cycle Time Scatterplot where teams can understand their Cycle Time trends, distributions, look at anomalies.

Question 2 Selectable Answer

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

Answer:
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.

Question 3 Selectable Answer

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

Answer:
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.

Question 4 Selectable Answer

Which of the following are considered Kanban practices for Scrum Teams? (choose the best answer)

A. Visualizing flow, limiting Work in Progress (WIP), actively manage the Work in Progress (WIP), inspecting & adapting the workflow.
B. Kaizen, removing bottlenecks, policies radiators, pull system.
C. Small batch sizes, limiting Work in Progress (WIP), eliminating waste, Kaizen.
D. Class of service, measuring cost of delay, visualizing the workflow, limiting Work in Progress (WIP), managing flow.
E. T-shirt size estimation, service level expectations, limiting Work in Progress (WIP).

Answer:
Explanation:
Central to the definition of Kanban is the concept of flow. Flow is the movement of value throughout the product development system. Kanban optimizes flow by improving the overall efficiency, effectiveness, and predictability of a process. Visualizing flow, limiting Work in Progress (WIP), actively manage the Work in Progress (WIP), inspecting & adapting the workflow are ways of optimizing flow.

Question 5 Selectable Answer

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

Answer:
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.

Question 6 Selectable Answer

True or False: A team's future performance can be determined by using Little's Law. (Choose the best
answer)

A. TRUE
B. FALSE

Answer:
Explanation:
Little’s Law cannot predict the future. For example, the effect of reducing WIP limits cannot be predicted
- it depends on whether the Scrum Team can achieve effective flow with lower WIP limits. Changes to the WIP limits can also be incorrectly influenced by only relying on cycle-time measurements.

Question 7 Selectable Answer

Which one of the following concepts does the Just-In-Time (JIT) method advocate? (choose the best answer)

A. Upstream processes run simultaneously with downstream processes.
B. Processes are triggered by a pull request based on demand.
C. Processes are initiated by a push request based on requirements.
D. The use of requirement planning to the maximum resource capacity.

Answer:
Explanation:
Kanban is often used in conjunction with JIT to avoid overcapacity of work in process. The just-in-time (JIT) strategy minimizes inventory and increases efficiency.

Question 8 Selectable Answer

Which of the following Scrum artifacts is a form of the Work in Progress (WIP) Limit? (choose the best answer)

A. The Product Backlog.
B. There is no such component in the Scrum framework.
C. The Sprint Backlog.
D. The Burn-down chart.
E. Definition of "Done".
F. The Sprint Goal.

Answer:
Explanation:
The Sprint Backlog is a WIP limit artifact that limits the number of items selected based on the Development Team's velocity or capacity.

Question 9 Selectable Answer

True or False: Scrum Teams using Kanban can replace Sprint Planning with just-in-time feature planning.

A. TRUE
B. FALSE

Answer:
Explanation:
Kanban does not replace or discount any part of the Scrum framework. It is designed to enhance and expand the practices of Scrum. Implementing Kanban assumes the reader is operating a process using the Scrum framework. Therefore, The Scrum Guide applies in its entirety.

Question 10 Selectable Answer

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

Answer:
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 11 Selectable Answer

How does Kanban support empiricism? (choose the best two answers)

A. The Kanban board provides transparency that helps the Scrum Teams inspect and adapt their process.
B. The Product Owner uses Kanban metrics to inspect the Throughput and adapt the Developers' Cycle Time accordingly.
C. Kanban prescribes specific practices that reduces the need for empiricism.
D. Kanban brings more rapid transparency about the product by enhancing and expanding the practices of Scrum. This enables a more effective inspection and adaptation loop.

Answer:
Explanation:
Scrum is founded on empirical process control theory, or empiricism. Key to empirical process control is the frequency of the transparency, inspection, and adaptation cycle - which we can also describe as the cycle time through the feedback loop.
When Kanban practices are applied to Scrum, they provide a focus on improving the flow through the feedback loop; optimizing transparency and the frequency of inspection and adaptation for both the product and the process.

Question 12 Selectable Answer

Who is accountable for the Definition of Workflow for the Sprint Backlog? (Choose the best answer)

A. The Developers.
B. The Product Owner.
C. The Scrum Team.
D. The Scrum Master.

Answer:
Explanation:
As the Developers have autonomy to determine how they turn the Sprint Backlog into an Increment, the Developers have the final say on the Definition of Workflow within the Sprint.

Question 13 Selectable Answer

What best describes an eight day 85% Service Level Expectation (SLE)? (choose the best answer)

A. 85% of all Product Backlog items are completed with 8 days remaining.
B. At least 85% of all Product Backlog items finished within 8 days.
C. The team expects a work item to be 85% complete by the end of 8 days of when they start the item.
D. The team expects they will complete a work item within 8 days of starting on it, 85% of the time.

Answer:
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 14 Selectable Answer

What might be discussed during the Sprint Retrospective if the Scrum Team is considering to use Kanban to complement their Scrum? (choose the best answer)

A. Workflows.
B. Current policies.
C. Work in Progress (WIP) Limits.
D. Metrics and charts such as cumulative flow, scatterplot, and work item aging.
E. All of the above.

Answer:
Explanation:
When Kanban practices are applied to Scrum, they provide a focus on improving the flow through the feedback loop; optimizing transparency and the frequency of inspection and adaptation for both the product and the process.

Question 15 Selectable Answer

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.

Answer:
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.
