|---|---|---|---|
Purposedifferent | After an incident with damage or a near miss, the method creates a sober field for learning without assigning blame. It directs attention to the course of events, conditions, and effective countermeasures. | 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 loud voices or hierarchy distort the idea search, the method creates a quiet entry into joint development. It gives everyone thinking space and gathers contributions without social brakes, making diversity more visible and easier to build on. |
