PMI Agile Certified Practitioner (PMI-ACP) — Question 29

A team using Kanban identifies that their cycle time has significant variation. After brainstorming, the team determines that the root cause is the stories' varying sizes and risks.
What should the team do?

Answer options

• A. Reduce work in progress (WIP) limits to accommodate slack for riskier stories
• B. Create a triage step on the Kanban board to pre-identify risky stories
• C. Set a policy to break down stories larger than a specified complexity, then adjust the WIP
• D. Create a dedicated overflow swim lane on the Kanban board for stories that are too large

Correct answer: C

Explanation

The correct answer is C because breaking down larger stories into smaller, more manageable tasks helps reduce variation in cycle time and allows for better risk management. Options A and D do not address the root cause of size and complexity, while option B may help identify risks but does not solve the issue of varying story sizes.
