Problem Management and Root Cause Analysis

Track bad actors and recurring failures, then run RCA to fix the root cause instead of the symptom.

Problem Management and Root Cause Analysis

If you fix the same failure three times, you are not maintaining — you are babysitting. Problem management breaks the cycle.

Spotting Bad Actors

  • Pull failure history by asset; sort by repeat count and downtime cost.
  • Any asset with three or more similar failures in a quarter is a bad actor.
  • Tag it as a problem, not a work order, so it gets a real investigation.

Running an RCA

  1. Capture the failure timeline: what happened, when, in what order.
  2. Use 5-Whys or a fishbone to trace symptoms to a root cause.
  3. Verify the root cause against evidence — do not settle for the first plausible answer.
  4. Assign a corrective action with an owner and a due date.
  5. Track it to closure and confirm the failure stops recurring.

Tips

Fix the root cause even when it is uncomfortable — redesign, spec change, or procedure rewrite. Patching symptoms guarantees the failure comes back.
