|---|---|---|---|---|
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 demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. | When a controversial topic needs depth and discipline at the same time, Fishbowl Discussion makes the structure of the conversation transparent. The format keeps the core small enough for real dialogue and open enough for controlled turnover. | When an idea hinges on one critical unknown, it prioritizes testing that exact piece of uncertainty first. It separates problem, assumption, solution, and evidence. The result is captured as a prioritized list of assumptions, a test plan, and a result report. |
