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.
