|---|---|---|---|---|
Purposedifferent | For recurring operational tasks or incidents, the method keeps solid action logic ready. It reduces uncertainty when time pressure, role changes, or rare situations demand fast access. | With many open commitments and ideas in daily life, a reliable external storage system emerges. The method relieves the mind so priority and context don't have to compete in memory. | 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. | With an overloaded day full of too many tasks, a realistic picture of the day emerges. The method connects estimating, deciding, and buffer thinking so planning fits available energy and time. |
