CORE DEFINITION

A consensus-based estimation method. Team members simultaneously reveal cards representing the size of work (based on the Fibonacci sequence) to avoid the anchoring effect (i.e., being influenced by the first person to speak).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Obtain independent judgments. When soliciting opinions in a meeting, have everyone write down their answers first, then reveal them simultaneously. This is the best low-cost means to eliminate groupthink and obtain true information.

anchor

Anchor fast decisions

Simultaneous card reveal ensures each person estimates based on independent judgment, avoiding anchoring by the first speaker. Discrepancies expose cognitive differences, discussion converges to consensus, and estimation quality is higher.

MINIMUM ACTION

In progress 0/2

Practice this model in one real situation:

First, explain the task to be estimated, each person holds Fibonacci cards. Second, reveal cards simultaneously
if differences are large, each person states their reasoning. Third, re-estimate until convergence, record the consensus value.
