It is a consensus-based estimation technique that produces quick and reliable estimates backed by the whole development team. It is highly recommended to purchase a purposed planning poker card deck.
A good planning poker card deck is based on the Fibonacci series- 1,2,3,5,8,13,20,40,100
👥Who
Everyone that does the work is involved, so typically only the developers should be involved
If the work item is wholly related to a specialism, e.g. research, UI design, testing then only team members who have experience of that specialism should take part.
🛠 Running the technique
Agree consensus on average value using a previously worked backlog item, e.g. a value of 5
The backlog item is presented by the product manager or delivery manager, with a short team discussion
Each team member allowed to vote, does so privately. The cards are then all shown.
If the scores are in general consensus, e.g. 3, 2,5, 3, 3, then the score is recorded
Where there is notable variation, e.g. 2, 3,3,5,10,5, then the members with the highest and lowest scores share their thinking. Everyone then repeats the activity, until consensus is reached.
