Important Scrum PSK-I Exam Questions

Answer: A

Explanation:

The Definition of Done (DoD) still applies even if policies are explicitly stated at each column of your workflow. The DoD is a fundamental concept in Scrum that ensures a shared understanding of what it means for work to be complete. Even with explicit policies at each stage of the workflow, the DoD provides a consistent standard for the team's deliverables, ensuring quality and alignment with stakeholder expectations

Answer: D

Explanation:

A Cycle Time Scatterplot is a visualization tool used to display the cycle times for individual work items over time. This scatterplot provides several types of qualitative information:

1. General Cycle Time Trends (Option A): The scatterplot can show general trends over time, such as whether the cycle times are decreasing, increasing, or staying stable. This helps teams understand the overall direction in which their workflow efficiency is moving.

2. Single Cycle Time Outliers (Option B): The scatterplot also helps identify individual outliers --- work items that took significantly longer or shorter than usual to complete. These outliers can be further investigated to understand why they occurred and to prevent similar situations in the future.

3. Clusters of Cycle Time Outliers (Option C): In addition to single outliers, the scatterplot may reveal clusters of outliers. These clusters can indicate systemic issues, such as bottlenecks or recurring problems in a specific part of the process.

Since a Cycle Time Scatterplot provides all these types of information (general trends, single outliers, and clusters of outliers), the correct answer is D.

Answer: E

Explanation:

During the Sprint Retrospective, once a team decides to supplement their Scrum with Kanban, all the mentioned elements might be considered:

* Workflow: To ensure it aligns with Kanban practices.

* Current policies: To review and adapt any team policies that may need to change.

* WIP Limit: To set appropriate limits to enhance flow.

* Metrics and charts (e.g., Cumulative Flow Diagram, Cycle Time Scatterplot, Work Item Aging): To visualize flow, identify bottlenecks, and make data-driven decisions for continuous improvement.

Considering all these elements helps the Scrum Team integrate Kanban practices effectively into their existing Scrum framework

Answer: A, C

Explanation:

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.

Answer: B

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
