Several tools are commonly used in RCA to identify root causes: - Five Whys: A simple iterative technique that involves asking "why" multiple times until the root cause is identified. - Fishbone Diagram: Also known as the Ishikawa or Cause-and-Effect Diagram, this tool helps categorize potential causes of problems. - Failure Mode and Effects Analysis (FMEA): A proactive tool that evaluates potential failure points within a process to mitigate risks before they occur.
