A burndown chart tracks how much work remains over time in an iteration (or release). The most direct inputs are the remaining work and the work completed (often expressed as tasks, story points, or hours). Therefore, to obtain burndown data efficiently, the PM should analyze remaining and completed tasks. This aligns with CompTIA Project+ Agile metrics concepts, where burn charts are used to visualize progress and forecast completion based on work remaining versus time.

The other options are not primary burndown inputs. “Number of people available” affects capacity and can influence how fast work burns down, but it is not what the chart directly measures. “Cost variance” is an earned value / financial control concept (more predictive/traditional) and not what burndown charts are built from. “Number of issues registered” is useful for quality and risk/issue tracking but does not represent the work remaining in the sprint backlog unless issues are explicitly counted as backlog items—and even then, the chart is still fundamentally about remaining work, not raw issue counts.

So, for efficient burndown extraction, the PM should use the team’s work tracking (sprint backlog/task board) to calculate remaining vs. completed tasks/work, which is exactly what the burndown visualizes.

Obtaining project sign-off is crucial in the closure phase, as it signifies formal acceptance of the project deliverables by the stakeholders. According to CompTIA Project+, project sign-off is a key milestone in officially closing the project.

Sprint 1 shows the highest velocity because velocity measures the amount of work completed during a sprint. In a burndown chart, this is shown by how much the actual remaining work decreases from the beginning to the end of the sprint. The red actual line drops most sharply during Sprint 1, moving from about 40 user stories to the mid-20s. This indicates the team completed the largest number of user stories during that sprint compared with the other sprints. Sprint 2 and Sprint 3 show smaller decreases, meaning lower completed work. Sprint 4 and Sprint 5 also show progress, but their reductions are not as large as Sprint 1. Therefore, Sprint 1 reflects the highest team velocity.
