A poor investigation blames the operator and closes with "retrain all." A good investigation finds system-level root causes and produces SMART corrective actions that change the system. Steps: secure the scene, build a timeline, identify root causes (Five Whys, Fishbone), write SMART corrective actions, and verify effectiveness.
A QEHS platform supports investigation quality with structured RCA templates, auto-populated timelines, CAPA linking with SLAs, and immutable evidence chains. See the [incident reporting use case](/use-cases/incident-reporting), [near-miss guide](/guides/near-miss-investigation-guide), and [CAPA glossary](/glossary/capa).
