Planning Poker
In plain terms
A consensus-based estimation technique using cards.
Going deeper
In planning poker, team members privately pick estimate cards then reveal together, discussing differences to reach consensus. It surfaces hidden assumptions.
Under the hood
Simultaneous reveal avoids anchoring; discussion of outliers improves shared understanding.
Examples
Agile estimation, story points, consensus, Fibonacci cards, sprint planning.
Think of it like...
Like everyone secretly guessing a jar's contents, then debating to agree.
