Poker planning is a lightweight, collaborative estimation technique used by agile teams to size work, reduce bias, and build shared understanding. Unlike a dry numbering exercise, it combines structured conversation with an engaging, card-based ritual that helps teams surface uncertainty, compare relative complexity, and make faster, more reliable forecasts. In this article I’ll explain how poker planning works, why it’s effective, how to run better sessions (in-person and remote), common pitfalls and practical fixes, and real-world lessons from my experience leading product teams.
What is poker planning and why it matters
At its core, poker planning (often called Planning Poker) replaces individual guesswork with a group process. Each participant privately chooses a card that represents their estimate for a user story (often on a Fibonacci-like scale). Cards are revealed simultaneously to avoid anchoring. Differences prompt short discussion until the team converges on a consensus estimate.
This method matters because estimation in software delivery is not just arithmetic — it’s social. Most risks come from misunderstandings, hidden constraints, edge cases, or differing assumptions. Poker planning turns estimation into a diagnostic ritual: when two developers pick widely different values, that disagreement is a signal to investigate, not a problem to paper over.
How poker planning works — step by step
- Preparation: Product Owner refines backlog items to a level suitable for estimation and ensures acceptance criteria are clear.
- Participants: Include developers, QA, the Product Owner, and a facilitator (scrum master or lead). Avoid observers who don’t participate.
- Scale: Use a consistent scale (common ones: 0, 1, 2, 3, 5, 8, 13 or powers-of-two). The goal is relative sizing, not hours.
- Round: For each story, the facilitator reads the story and its acceptance criteria. Any clarifying questions are asked (briefly).
- Private estimate: Each estimator privately selects a card.
- Reveal: All cards are revealed simultaneously to avoid anchoring effects.
- Discuss: If values differ, the highest and lowest explain their reasoning. Discuss until convergence or for a fixed number of iterations.
- Decide: Re-vote if needed, or take the average/consensus. Record the agreed estimate and proceed.
Choosing a scale and what it implies
Most teams use a non-linear scale to reflect uncertainty growth with size. Fibonacci-like scales or exponential scales (1,2,3,5,8,13…) emphasize that larger items carry disproportionate unknowns and should be split whenever possible. Use "0" for trivial tasks and "?" when the item needs more analysis before estimation.
Practical tips for accurate poker planning
- Time-box: Keep each story discussion short — 2–5 minutes is often enough for well-groomed items. If it takes longer, flag the item for refinement.
- Limit participants: In very large groups, vote with representatives to avoid social loafing and long discussions.
- Calibrate regularly: Pick a reference story (a typical "5") so new members can align their mental model to the team’s velocity and complexity norms.
- Use history: When similar items have known outcomes, reference past velocity and completion effort to inform estimates.
- Split big items early: Anything above a chosen threshold (often 8 or 13) should be broken down into smaller stories before planning.
Remote poker planning — tools and techniques
Remote work is now normal for many teams. Digital planning poker tools replicate the card experience and provide features like timers, story linking, and vote anonymity. Popular approaches include integrated plugins in Jira, dedicated apps (PlanningPoker.com, Pointing Poker), or general collaboration tools like Miro and Zoom combined with polling. One small habit change helps a lot: ask participants to mute cameras only when not speaking, so subtle cues and engagement remain visible.
Scaling poker planning for larger programs
When more than one team is involved, a multi-level approach works well. Use a lightweight "big room" estimation (bucket estimation or t-shirt sizing) to create rough alignment across teams, then have each team perform their own poker planning on the decomposed backlog. For cross-team features, include representatives from each affected team for the detailed session.
Common pitfalls and how to fix them
- Anchor bias: If someone shares numbers early, others may converge prematurely. Enforce the simultaneous reveal rule to counter this.
- Dominant voices: Strong personalities can skew estimates. The facilitator must ensure quieter voices contribute and that explanations come from different perspectives.
- Estimating hours, not complexity: Poker planning is for relative sizing; converting story points to hours is a secondary activity tied to velocity, not the immediate estimate.
- Ignoring expertise: Sometimes QA or Ops concerns are left out. Make sure the cross-functional team participates so non-coding complexities are captured.
- Using it as commitment: Treat estimates as forecasts, not promises. Use velocity and empirical data to turn estimates into reliable planning over time.
Measuring success and improving accuracy
Estimation accuracy improves when you close the feedback loop. Track planned story points vs. done points, analyze major misses, and discuss root causes in retrospectives. Over time teams develop a calibrated sense of size — that intuition is the real value poker planning builds. I worked with a mobile product team that reduced estimate variance by 40% over three sprints after instituting a single "reference story" and weekly calibration touchpoints; that made sprint planning far faster and reduced mid-sprint surprises.
When poker planning is not the right tool
There are times when poker planning is overkill. For tiny, well-understood tasks or tickets requiring little cross-functional discussion, quick triage and fast prioritization are better. Conversely, when a ticket is a research or discovery task, use spike tasks and separate time-boxed exploration rather than forcing a point estimate.
Example session — a realistic walkthrough
Imagine you’re estimating a story: “Implement search with autocomplete for product catalog.” The PO reads acceptance criteria: API endpoints, performance goals, and UX expectations. Some developers think it’s a 5 (existing search framework can be reused). One picks 13 (concerned about indexing and edge cases with internationalization). Simultaneous reveal shows a split. The 13 explains index rebuild concerns; the 5 explains reuse strategy. They discover a missing acceptance criterion for synonyms and locales. The team decides to split: a 5 for core autocomplete, a 3 for internationalization background work, and a 2 for synonym mapping. The result: clearer scope, smaller risks, and more predictable delivery.
Tools and resources
There are many tools to facilitate poker planning sessions. For remote teams, consider an integrated option with your issue tracker so votes attach directly to stories. For in-person teams, a simple deck of planning cards and a visible board are often enough.

Final checklist to run an effective poker planning session
- Backlog items properly groomed with clear acceptance criteria.
- Cross-functional attendance (developers, QA, PO, facilitator).
- Reference story for calibration.
- Timeboxes for each story and the overall session.
- Rules for splitting large items and handling “?” votes.
- Follow-up: record decisions and actions, and review estimation outcomes in the next retrospective.
Closing thoughts
When done well, poker planning becomes more than an estimation ritual; it’s a team learning mechanism. It converts ambiguity into conversations, aligns expectations early, and codifies a shared language about complexity. I’ve seen teams move from contentious, hour-by-hour debates to efficient, trust-based estimation that lets them plan reliably while preserving agility. If you’re just starting, run a short pilot with a few stories, keep the atmosphere curious rather than judgmental, and iterate on the process — your estimates and team cadence will improve together.
