What is Planning Poker? A Complete Guide to Agile Estimation
Learn how Planning Poker improves agile project estimation, why it works and how to introduce it effectively in a Scrum team.
What is Planning Poker?
Planning Poker, also known as Scrum Poker, is a collaborative consensus-based agile estimation technique. The team uses numbered cards to compare the effort, complexity and uncertainty of user stories.
Secret voting prevents the first opinion from influencing everyone else. After the simultaneous reveal, differences become a focused conversation about risks, requirements and technical approaches.
How Planning Poker works
Main goal
Create a shared estimate with input from the whole team without favoring the most influential opinion.
Collaborative process
Combine individual reflection, simultaneous reveal and discussion to build understanding before reaching consensus.
- The Product Owner presents the story and its acceptance criteria.
- The team clarifies questions, dependencies, risks and scope boundaries.
- Each participant chooses a card without showing anyone else.
- Everyone reveals their cards at the same time.
- People with the most distant estimates explain their reasoning.
- The team votes again until it reaches a useful consensus.
Why use the Fibonacci sequence?
Growing uncertainty
The larger the story, the less precise an estimate can be. Wider intervals represent that uncertainty.
No false precision
The team avoids spending time debating tiny differences between nearby values.
A signal to split
Very high estimates suggest that the story may need to be split or clarified.
Benefits of Planning Poker
Reduces anchoring bias and the influence of dominant opinions.
Reveals risks, dependencies and different interpretations of a requirement.
Shares technical knowledge among participants.
Improves engagement and collective ownership.
Helps the team plan with a consistent relative reference.
Turns differences in votes into objective conversations.
How to run Planning Poker: step by step
Prepare the session
Select refined stories, bring together the people who will do the work and choose the card scale.
Present the story
Explain the goal, expected value and acceptance criteria without suggesting an estimate.
Discuss the scope
Clarify questions and identify integrations, testing, risks and relevant technical work.
Vote privately
Each participant chooses the card that best represents effort, complexity and uncertainty.
Reveal simultaneously
Show all votes together so that assessments remain independent.
Discuss the differences
Start with the extremes and look for information that part of the team may not have considered.
Vote again
Repeat after the discussion. If disagreement remains, clarify or split the story.
Planning Poker cards and values
A common scale uses 0, 1, 2, 3, 5, 8, 13 and 21. The wider intervals reflect growing uncertainty.
How to interpret the values
- ? — there is not enough information to estimate
- ☕ — the participant suggests a break
- 21+ — the story probably needs to be split
Tips and best practices
- Define acceptance criteria before voting.
- Include the people who will implement and test the work.
- Keep the conversation focused on the story scope.
- Do not use story points to compare people or teams.
- Record important assumptions discovered during the discussion.
- Refine the scale based on the team's own context.

Planning Poker frequently asked questions
Does Planning Poker estimate hours?
Teams usually use story points to compare effort, complexity and uncertainty. Hours can be used, but they may imply precision that does not exist yet.
How many people should participate?
Include the people needed to perform and understand the work. Smaller groups make discussion easier; large teams can split the session.
What if the team cannot agree?
Explore the extremes, clarify assumptions and vote again. If the difference remains, gather more information or split the story.
Does it work for remote teams?
Yes. An online room preserves private choices, simultaneous reveal and equal participation across locations.
