1. Start with a clear event statement
Describe what happened, where and when it occurred, and the actual or potential impact. Avoid assigning blame or naming a preferred cause before evidence is reviewed.
2. Build the sequence
Use records, interviews, observations, and relevant data to establish a reliable timeline. Separate confirmed facts from assumptions and unresolved questions.
3. Identify contributing system factors
Explore the work environment, task design, communication, equipment, policies, training, staffing, and organizational conditions that influenced the event.
4. Design stronger actions
Prefer changes that redesign the system, simplify work, add forcing functions, or improve standardization. Assign owners, measures, due dates, and a plan to verify effectiveness.
