|---|---|---|---|---|
Purposedifferent | When a group needs to connect many viewpoints in a short time, World Café creates a calm alternation between closeness and rotation. It sets thinking in motion without forcing the conversation into full-plenary rigidity. | When many hypotheses compete for attention, it brings order to their learning sequence and importance. It separates problem, assumption, solution, and evidence. The result is captured as a prioritization canvas and a hypothesis backlog. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
