Why is planning poker an effective estimation technique?

Question

Options

• AIt generates a lot of useful discussion and gets team buy-in.
• BIt results in lower estimates as team members will estimate individually.
• CIt triggers a more detailed and task oriented break-up of the story.

• B

• C

Explanation

Planning poker is effective primarily because it surfaces disagreements and drives meaningful conversation among team members - when estimates diverge, the team must discuss why, uncovering hidden complexity, risks, and assumptions that might otherwise go unnoticed. This collaborative process also creates shared understanding and buy-in, since everyone on the team has actively participated in the estimate rather than having one imposed on them.

Option B is wrong because planning poker doesn't inherently produce lower estimates - in fact, discussion often raises estimates when hidden complexity is revealed. The value is in accuracy and alignment, not deflation.

Option C is wrong because task breakdown is a separate activity (like sprint planning or story decomposition); planning poker estimates story effort at a high level, not task-level detail.

Memory tip: Think of planning poker as a "forcing function for conversation" - the cards aren't the point, the debate they trigger is. If you remember that its main value is discussion + consensus, you'll always land on A.
