1 What is an incident investigation?

An incident investigation is a structured process of collecting and analyzing information about an incident to determine what happened, why it happened, and how to prevent it from happening again. This should involve a multidisciplinary team of people with the relevant knowledge, skills, and experience.

Utilize a systematic and objective approach to collect and analyze the data, like the 5 Whys or fault tree analysis. Concentrate on the root causes of the incident, not the symptoms or blame. Develop SMART corrective actions that address the root causes and prevent recurrence. Monitor and evaluate the implementation and effectiveness of the corrective actions. Document and report the investigation results and recommendations in a clear and concise way. Finally, communicate and disseminate the investigation findings, recommendations, and lessons learned to relevant stakeholders.
