Scrum PSK-I Exam - Topic 4 Question 18 Discussion

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.
