The correct answer is D — Iteration Burndown Chart.
An iteration burndown chart provides daily updates about the team’s progress during an iteration (or sprint). It tracks the remaining work in the sprint backlog and helps both the team and stakeholders assess if the sprint goal is likely to be met. This visualization helps communicate real-time progress to key stakeholders and supports adaptive planning.
PMI Agile Practice Guide states:
“Burndown charts display work remaining in a timebox and are updated daily. They are effective for communicating iteration progress to the team and stakeholders.”
(PMI Agile Practice Guide, Section 5.6, Information Radiators)
PMBOK® Guide (6th Edition) and Mike Griffiths both emphasize using task boards and burndown charts as “information radiators” for transparency.
Mike Griffiths’ PMI-ACP Exam Prep Book elaborates:
“Iteration burndown charts are the most widely used artifact to track sprint progress. They offer insight into how much work remains and signal whether the team is on track to meet its sprint goal.”
Options A and B are long-term planning tools. Option C (velocity) is a forecasting metric and not updated daily.
Answer: D
