What is Power of 2 planning poker?
In Power of 2 planning poker, team members estimate the size of a task using numbers that are powers of two (1, 2, 4, 8, 16, 32, 64, etc.). This scale grows rapidly, making it easier to express uncertainty for larger or more complex tasks. The clear separation between values helps teams quickly identify when a task is significantly larger than another.

Frequently Asked Questions
Planning Poker is a consensus-based estimation technique used by agile teams to estimate the effort or relative size of development goals. Team members make estimates by playing numbered cards face-down, then revealing them simultaneously. This approach prevents the anchoring bias that occurs when team members are influenced by the first estimate they hear.
The purpose of planning poker is to help teams estimate the effort or relative size of development goals more accurately and efficiently.
The numbers in planning poker depend on the chosen method. For example, the Fibonacci method uses the Fibonacci sequence, which starts with 0 and 1, and each new number is the sum of the previous two (0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc.).
