Exam Preparation Quiz

Explanations for each answer:

• Burndown is incorrect. Burndown charts show the amount of work remaining versus time, but don't specifically track how long it takes to close a work item or count completed backlog items in the way required.
• Cycle time is correct. Cycle time measures how long it takes for a work item to progress from active status to completed status, directly addressing the requirement to track how long it takes to close a work item.
• Lead time is incorrect. Lead time measures the total time from when work is requested (created) until it is delivered (closed), which is broader than the specific time to close an active work item.
• Sprint capacity is incorrect. Sprint capacity helps track team members' available time during a sprint, but doesn't provide information about work item completion time or count completed backlog items.
• Cumulative flow is correct. Cumulative flow diagrams track the number of work items in each state over time, providing clear visibility into completed backlog items and helping identify bottlenecks in the workflow.
