Planning Poker (also known as Scrum Poker) is a very popular technique proposed in 2002 by James Grenning. Each player uses a set of cards with Fibonacci sequence numbers on it to estimate the overall effort of a task in Story Points.
Planning Poker procedure
Take in mind that with great popularity came multiple variations of this technique, each team tend to adapt it for their needs. Classic procedure is as follows:
- The Product Owner provides a short overview of a user story that will be estimated by the team. The team can ask questions. Potential clarifications can influence the initial scope.
- Everyone from the team picks one card from his set (1, 2, 3, 5, 8, 13 …) and lays it face down in front of him.
- When everyone is ready, the team is turning over cards.
- Members with the highest and lowest estimates should justify their votes and discussion continues.
- Repeat steps 2-4 until a consensus is reached.
Mind the fact, that consensus doesn’t necessarily mean that everyone needs to put the same number. The team might just agree to disagree and put the average or largest number as an estimate.
