What is Planning Poker: A Guide to Agile Estimation

Estimating tasks in Agile projects often leads to uncertainty. If one person thinks a feature will take hours to complete, another believes it will take days. Communication becomes longer, assumptions are unclear, and teams are unsure. If you have been part of such a team experience, then you understand the challenge of making fair and accurate estimates. This is where understanding What is Planning Poker can make a world of difference.

It comes in to provide a smarter way forward. It builds a simple, collaborative space where everyone can share their views, make accurate project planning, and reveal estimates together. In this blog, you will learn What is Planning Poker, how it works, its benefits, its goals and more. So, keep reading to learn more!

What is Planning Poker?

Planning Poker is a widely utilised Agile estimation technique that helps teams to estimate the effort required for user stories or features. It converts estimation into an engaging and collaborative activity, where team members have equal say. This enables teams to agree on a realistic estimate instead of relying on one person’s opinion.

A Planning Poker session begins when the Product Owner explains a user story, and each estimator is given a deck of cards. After the discussion is over and doubts are clear, everyone selects a card and reveals it together. If values match, that becomes the estimate; if not, the team discusses the differences and votes again until they reach a consensus.

How Does Planning Poker Work?

Planning Poker brings together stakeholders from various departments within the organisation to reach a consensus on the estimated effort required for several backlog initiatives. In an Agile software organisation, stakeholders can include a Product Owner, Developers, User Experience (UX) Designers, QA Testers, and Product Managers, among others.

a) Step 1: Hand out the Cards

Participants receive identical decks of cards (or chips), each featuring a different number. A common sequence involves doubling each number: 1, 2, 4, 8, 16, 32, 64. Mike Cohn of Mountain Goat Software, who popularised Planning Poker for Agile development, recommends the sequence 0, 1, 2, 3, 5, 8, 13, 20, 40, and 100.

Such decks feature strategic number intervals to assist participants in reaching a consensus estimate for each story. Providing too many options, such as each number from 1 to 50, would make the process inefficient.

b) Step 2: Read the Story

In this step, the Product Owner, or possibly a Product Manager, reads each story aloud to the group. This ensures everyone hears the same description and understands the features from the perspective of the customer. Here, it includes explaining the acceptance criteria, business value, key details, and any dependencies.

c) Step 3: Discuss

Once everyone has heard the story, the group discusses it. Participants describe how they envision tackling the work, how many estimated individuals would be involved, which skill sets will be required, and any obstacles they foresee slowing progress. The group also uses this time to ask questions about the story.

d) Step 4: Estimate and Share

After everyone has shared their viewpoints and questions are clarified, each participant selects a card. This selection reflects their estimate of the story’s effort. When everyone is ready, the team reveals their cards, with higher values indicating a belief that the story will be more difficult or time-consuming.

e) Step 5: Work Towards Consensus

If every participant reveals the same card, the value becomes the consensus estimate and moves to the next story. If card values differ, the team continues to provide their reasoning for the estimates they provided. After the discussion, everyone reconsiders their choice, selects a card again, and reveals together until agreement is reached.

Benefits of Planning Poker

Planning Poker is a simple, team-based way to estimate work, and it comes with quite a few benefits:

1) Better Teamwork and Bonding: Planning Poker feels a bit like a group game where everyone comes together to figure out how long tasks might take. As the team discusses and shares ideas, people start understanding each other better, which naturally builds stronger connections.

2) Improved Collaboration and Communication: It’s all about reaching a common agreement. Everyone shares their view, listens to others, and then the team settles on a final estimate together. It’s like agreeing on a movie to watch with family. This makes communication clearer and more effective.

3) Creates a Sense of Ownership: Since the whole team decides the estimates together, everyone feels like they’re part of the outcome. It’s similar to building something as a group; you feel proud because you contributed to it. That shared ownership really matters.

4) Builds Trust With Stakeholders: When a team takes the time to carefully estimate work, they can give more reliable timelines. This makes them come across as dependable and trustworthy to Managers and customers.

5) Leads to Better Accuracy Over Time: The more the team practices Planning Poker, the better they get at estimating. Over time, they become more confident in predicting how long things will take.

6) Encourages Equal Participation: Everyone gets a chance to voice their thoughts, so no one feels left out. It’s like making sure every person in a group gets their turn to speak, fair and inclusive.

7) Helps Avoid Bias: Each person shares their estimate independently, so no one’s opinion dominates the conversation. This keeps things fair and prevents influence from overpowering voices.

Drawbacks of Planning Poker

Here are some key limitations of Planning Poker that teams should be aware of:

1) Illusion of Accuracy: Achieving agreement during estimation can sometimes create a misleading sense of certainty. Despite alignment, the team may still overlook critical details, resulting in inaccurate estimates.

2) Dominance Bias: Strong personalities within the group can unintentionally sway others’ opinions. If not carefully moderated, this may lead to estimates shaped more by influence than by balanced team input.

3) Group Optimism: Studies suggest that teams often produce more optimistic estimates compared to individuals working alone. As a result, discussions during Planning Poker sessions may lead teams to overestimate what they can realistically accomplish within a given timeframe.

Planning Poker Origin

The origin of Planning Poker goes back to the technique known as Wideband Delphi, developed by RAND Corporation for estimating complex tasks. In 2002, software entrepreneur James Grenning polished the idea and adapted it for Agile teams, giving it the name Planning Poker.

After a few years, in 2005, Mike Cohn of Mountain Goat Software popularised the method through his book “Agile Estimating and Planning.” This helped Planning Poker turn into one of the widely used estimation practices in the domain of Agile development today.

Who Participates in Planning Poker?

Planning Poker involves the entire Agile team, including Product Owners, Testers, Developers, and other relevant stakeholders. Everyone collaborates to estimate the effort required for completing user stories, ensuring diverse perspectives.

What is the Goal of Planning Poker?

The goal of Planning Poker is to produce accurate, team-driven estimates by encouraging discussion, knowledge sharing, and consensus. It helps Agile teams assess task complexity collaboratively, identify uncertainties early, and align on realistic expectations for sprint planning.

Conclusion

Planning Poker turns estimation into a clear, collaborative, and confidence-building process. Understanding What is Planning Poker, helps Agile teams to make smarter decisions, bring out hidden details, and create a shared ownership of the upcoming work. This makes estimation sessions effective, fair, and engaging.
