|---|---|---|---|---|
Purposedifferent | Three Horizons helps clarify strategic options across different timeframes. It compares strengths, risks, market logic, and investment choices, and captures the result as a horizon map, portfolio view, and initiatives per horizon. | 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. | After missions or project phases with unclear outcomes, the method makes visible what actually happened and what can be learned from it. It separates course, effect, and causes so experience turns into solid improvement. | 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. |
