Which chart is utilized to measure the number of completed items per iteration?

The throughput chart is specifically designed to track the number of work items completed over a specific period, often represented in iterations or sprints. This visualization helps in measuring productivity and assessing the flow of work within a process. By displaying how many items are finished within designated time frames, a throughput chart effectively communicates performance trends, allowing teams to identify patterns, evaluate their capacity, and optimize processes for future iterations.

Other charts, while related to project tracking and measurement, focus on different aspects. For instance, the burndown chart illustrates the amount of work that still needs to be completed in a project, displaying remaining work over time. The burnup chart shows completed work against total work, helping to visualize progress toward the goal, but not specifically measuring iterations. The velocity chart, relevant in agile methodologies, calculates the amount of work a team completes in a sprint, typically measured in story points, not explicitly in terms of items completed. Each of these alternatives serves unique purposes, but the throughput chart is the most suitable for directly measuring the number of completed items per iteration.
