More details for a story are required before the upcoming sprint planning meeting.

The correct answer is C – Schedule a story grooming session with the product owner before sprint planning. Story grooming (backlog refinement) ensures that stories are ready, appropriately detailed, and understood before planning.

From the PMI Agile Practice Guide:

“Backlog refinement sessions are a key practice where the team, facilitated by the Scrum Master, ensures that backlog items are well-defined and sized appropriately for future planning. These sessions reduce ambiguity and promote shared understanding.”

(PMI Agile Practice Guide, Section 5.3 – Backlog Refinement)

Mike Griffiths adds:

“Backlog refinement allows stories to be clarified, split, and estimated ahead of planning. Agile practitioners ensure backlog items meet the Definition of Ready (DoR) before sprint planning.”

(Mike Griffiths, PMI-ACP Exam Prep, Chapter 5 – Adaptive Planning)

Incorrect options:

A delays collaboration and is too passive.

B lacks product owner involvement.

D is a sizing technique, not a requirement clarification method.
