Question 1

A cumulative flow diagram can show you:

(Choose the best two answers)

AThe total amount of Work in Progress (WIP) for a specific date.

BThe average Throughput for a specific date range.

CThe Cycle Time for an item that completed on a specific date.

DThe exact average Cycle Time for all items completed on a specific date.

Answer : A, C

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. Reference: The Kanban Guide for Scrum Teams.

Question 2

When the Developers limit Work in Progress (WIP) inside a Sprint, what would you expect to observe?

(Choose the best three answers)

AThe Developers would stop beginning work, and instead, start finishing work.

BThe amount of work done by the end of the Sprint would be reduced.

CIncreased collaboration/swarming between the Developers.

DSelf-management would be strengthened as a result of increased transparency.

Answer : A, C, D

When WIP limits are implemented, Developers are encouraged to focus on completing existing tasks rather than starting new ones. This leads to a more collaborative approach, as team members may swarm to complete items together. Additionally, limiting WIP enhances transparency in the process, which in turn strengthens self-management by the team. These principles align with Kanban's emphasis on active management and the Scrum framework's focus on collaboration. Reference: The Kanban Guide for Scrum Teams.

Question 3

What flow metric best indicates when multiple items from the Product Backlog will be finished?

AThroughput.

BCycle Time.

CWork Item Age.

DWork in Progress (WIP).

Answer : B

Cycle Time measures the time it takes for a single work item to go from start to completion. By understanding Cycle Time, a team can forecast when multiple items from the Product Backlog will likely be finished based on the average duration it takes to complete an item. This is essential in Kanban as it provides insight into the delivery timeline and is crucial for planning and predictability within a Scrum context. Reference: The Kanban Guide for Scrum Teams.

Question 4

Which of the following are flow metrics needed when doing Scrum with Kanban?

(choose the best four answers)

AThroughput.

BLead Time.

CCycle Time.

DWork in Progress (WIP)

EWork Item Age

FCFD

Answer : A, B, C, D

The essential flow metrics for Scrum Teams utilizing Kanban are:

Throughput: Measures the number of items completed within a time period.

Lead Time: Time from when an item enters the system to when it exits.

Cycle Time: Time it takes to complete a work item once it starts.

Work in Progress (WIP): The number of items currently in progress but not completed.

These metrics are foundational in understanding and optimizing flow within Kanban systems used alongside Scrum. 'Work Item Age' and 'Cumulative Flow Diagram (CFD)' are useful metrics but are not listed as primary flow metrics in Kanban for Scrum Teams.

Question 5

Who is in the best position to decide if Kanban may be a valuable complementary practice for a Scrum Team?

(choose the best answer)

AThe Scrum Master.

BThe Scrum Team.

CThe Developers.

DThe Product Owner

EStakeholders

Answer : B

The decision on whether Kanban is a beneficial complement to Scrum lies with the entire Scrum Team. This includes the Product Owner, Scrum Master, and Developers, who collaboratively evaluate their workflow and decide if Kanban practices would improve flow and meet their specific needs. This is not the responsibility of a single role but a collective decision for effective self-management and ownership.

Question 6

What is the potential benefit of limiting Work in Progress (WIP)?

(choose the best answer)

AShorter feedback cycles.

BMore sustainable pace of work.

CFaster realization of value.

DImproved collaboration.

EAll of the answers.

Answer : E

Limiting Work in Progress (WIP) has several potential benefits for a Scrum Team, including:

1. Shorter feedback cycles (Option A): By limiting the amount of work in progress, the team can focus on completing work faster, which leads to shorter feedback loops and quicker validation of hypotheses or deliverables.

2. More sustainable pace of work (Option B): Limiting WIP helps prevent overburdening the team, promoting a more balanced and sustainable work pace.

3. Faster realization of value (Option C): By completing items more quickly and reducing multitasking, the team delivers value faster to stakeholders.

4. Improved collaboration (Option D): When WIP is limited, team members are more likely to collaborate to finish tasks that are already in progress rather than starting new ones.

Question 7

What should the Developers do if, during the Sprint, the Product Owner asks them to add an

urgent unplanned work item that aligns to the Sprint Goal but does not fit into the current Work

in Progress (WIP) Limits?

(choose the two best answers)

AAdd the urgent item to their Sprint Backlog but only start working on it when their
WIP Limits allow it.

BAdjust the WIP Limits to allow for taking on the extra item and record it as part of
their Definition of Workflow.

CTake on the urgent item as an exception to the WIP Limits and visualize that
they are above their WIP Limit.

DReject the urgent item since the WIP Limits do not allow it. Tell the Product
Owner to wait until the next Sprint.

Answer : A, C

If the Product Owner requests that an urgent, unplanned work item be added during the Sprint, and it aligns with the Sprint Goal but does not fit within the current WIP limits, the Developers should:

1. Add the urgent item to their Sprint Backlog but only start working on it when their WIP Limits allow it (Option A): This maintains the integrity of the WIP limits and ensures that the team doesn't overcommit or create too much work in progress, which could affect flow and focus.

2. Take on the urgent item as an exception to the WIP Limits and visualize that they are above their WIP Limit (Option C): By taking on the urgent item as an exception, the team can address the urgency while being transparent about the temporary breach of the WIP limits. This visualization helps the team and stakeholders understand the current state of work and its impact(

Options B (Adjust the WIP Limits) and D (Reject the urgent item) are less suitable because they either undermine the WIP control mechanism or fail to accommodate a potentially critical change that aligns with the Sprint Goal.
