|---|---|---|---|---|
Purposedifferent | When collaboration needs more than implicit expectations, it lays out shared ground rules openly. It creates reliability for conduct, availability, and decision paths. | 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. | For operational work in a distributed team, the method links communication with direct system control. It records decisions right where the signal, the context, and the execution come together. | After a project phase with mixed results, the method makes learning from the individual case reusable. It connects events, decisions, and systemic conditions into robust insights. |
