Purposedifferent | 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. | For a complex deviation with several people involved, the method bundles problem, analysis, and decision onto one page. It creates a shared working space where causes, countermeasures, and follow-up fit together. | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. |
