Planning Poker
Planning Poker is an estimation technique in Scrum that promotes consensus- based effort estimations. Team members make estimates by playing numbered cards face-down, instead of speaking them out loud, to avoid cognitive bias. Once everybody has chosen a card, the cards are revealed and the estimates discussed, with high and low estimators explaining their reasoning. The process is repeated until a consensus is reached. This method is highly collaborative and every perspective is considered, resulting in more accurate estimations.
Guide: Planning Poker in PSM I: Understanding and Exam Preparation
Planning Poker is a pivotal part of Scrum's software estimation process.
Why is it important?
It promotes team communication, it's a democratic process and leads to more accurate estimation as it includes perspectives from all points of view.
What is it?
Planning Poker is a consensus-based estimation technique. Each participant gets a set of cards with numbers indicating the amount of effort required to complete a task. These numbers follow the Fibonacci sequence, which increases exponentially.
How does it work?
A task is presented and each team member independently selects a card that represents their effort estimate. All cards are then revealed simultaneously. If estimates vary greatly, the highest and lowest estimators discuss their reasoning, and the process repeats until consensus is reached.
