Planning Poker Best Practices

Planning Poker Best Practices

Planning poker is a consensus-based estimation technique where each team member privately selects an estimate, then all estimates are revealed simultaneously. It prevents anchoring bias and encourages discussion.

The Basic Process

1. Present the story -- The product owner describes the user story and acceptance criteria.
2. Discuss briefly -- Clarify questions, but do not debate estimates yet.
3. Everyone votes -- Each person selects a card (or clicks a value in a digital tool) without showing others.
4. Reveal -- All estimates are shown at once.
5. Discuss outliers -- The highest and lowest estimators explain their reasoning.
6. Re-vote if needed -- Repeat until the team converges.

Key Best Practices

Time-box each story. Spend no more than 5 minutes per item. If consensus is not reached, take the higher estimate and move on.

Let the lowest and highest speak first. They often surface risks or simplifications others missed.

Do not average. Planning poker aims for consensus, not arithmetic. If half the team says 5 and half says 13, you have a conversation to have, not a number to compute.

Use a reference story. Before starting, remind the team of a known story and its estimate: "Remember, our login form refactor was a 5."

Include everyone. Developers, testers, designers -- anyone who touches the work should vote. Excluding people leads to blind spots.

Common Pitfalls

• Anchoring -- A senior developer says "this is easy" before voting, biasing everyone toward a low number. The simultaneous reveal prevents this.
• Velocity gaming -- Inflating estimates to look good later. The Scrum Master should watch for sudden estimate inflation.
• Analysis paralysis -- Spending 20 minutes on a single story. Time-boxing fixes this.
