Purposedifferent | When a group without a fixed agenda needs to get into useful conversations quickly, Lean Coffee structures the start around interests rather than a presentation. The group itself negotiates which topics get time first and which wait. | 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 problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. | Peer Instruction uses group thinking to clarify difficult terms or concepts faster. The method combines individual reflection with social correction and shared precision. |
