|---|---|---|---|---|
Purposedifferent | When a team is starting fresh or working past each other, Team Charter clarifies the shared working basis. It visibly sets out how collaboration, decision paths, and mutual conduct should work day to day. | 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. | During an acute incident with several people involved, the method creates a clear leadership and communication structure. It reduces chaos when fast coordination and clean situational awareness are both needed at once. | When several teams collaborate repeatedly, it describes the right interaction mode for each interface between them. It clarifies responsibility, interaction, and load between teams. The result is captured as an interaction heat map and pairwise agreements. |
