What Is Planning Poker?

The short version

Planning Poker is a consensus-based estimation technique used mostly by agile software teams. Instead of one person guessing how much effort a piece of work will take, every team member estimates independently and reveals their card at the same time. Differences get discussed, then the team re-votes until they converge on a number.

How a round works

A host reads out (or shares) the story being estimated. Everyone privately picks a card representing their estimate - nobody can see anyone else's pick yet, which is the whole point: it stops the first person to speak from anchoring everyone else's opinion. Once everyone has voted, all cards flip at once.

If everyone lands on the same number, the estimate is confirmed and the team moves to the next story. If the votes are spread out, the people with the highest and lowest estimates explain their reasoning - often they know something the rest of the team missed - and the team votes again.

Why the cards use a Fibonacci-like sequence

Most Planning Poker decks use values like 1, 2, 3, 5, 8, 13, 21 - roughly the Fibonacci sequence. The gaps get wider as the numbers grow, which matches how uncertain estimation actually is: the difference between a 1-point and 2-point task is meaningful, but the difference between "definitely a 20" and "definitely a 21" almost never is. Wide decks stop teams from wasting time debating precision they can't actually deliver.

Why teams bother with it

A single expert guessing effort tends to anchor too optimistically, or too conservatively based on whoever's most confident in the room. Planning Poker surfaces disagreement early - before the work starts, not mid-sprint - and the discussion it triggers is often more valuable than the number itself: it's where hidden assumptions and missing requirements come out.

Doing it with a remote team

The original version used physical playing cards around a table, which obviously doesn't work for distributed teams. Online tools like Fibopoker replace the cards with a shared session link - participants join without installing anything or creating an account, vote on their own screen, and the reveal happens for everyone at once, same as the physical version.
