Incident Investigation/Root Cause Analysis Problems

Have you ever seen people have any of these root cause analysis and incident investigation problems at your company? For example, people:

  • Call human error a root cause.
  • Focus on blame. (It was a stupid decision, or they should have known better.)
  • Start looking for why the incident happened before they know what happened.
  • Avoid topics because they are “off limits.”
  • Create a cover story to avoid blame.
  • Jump to conclusions
  • Look for evidence that proves what they think caused the accident.
  • Can’t decide who is telling the truth. (Disagreement between witnesses.)
  • Consider the incident to be a “freak accident” and not worthy of investigation.
  • Don’t look for similar incidents from the past and consider why previous corrective actions didn’t prevent recurrence.
  • Make assumptions and start believing they are facts without proof.
  • In an interview, don’t let people tell their story and, instead, bombard them with questions.
  • Have lawyers lead the investigation.
  • Are given the investigation to do in their spare time.
  • Have management tell them the results of the investigation before it starts, because “we already know what the causes are.”
  • Pick root causes from an approved list.
  • Use 5-Whys to find “the” root cause.
  • Never had any root cause analysis training.
  • Use the same old corrective actions that have always been approved before.
  • Have favorite causes that they tend to look for.
  • Leave things out of their report because they are too controversial.
  • Are given an arbitrary, short deadline for an investigation.
  • Assign too many people to an investigation team.
  • Provide too few resources to perform an investigation.
  • Have the wrong people on an investigation team.
  • Assign the root cause analysis to the supervisor.
  • Fail to ensure effective corrective actions are implemented.
  • Focus on “the report” rather than what needs to be done to improve performance and mitigate risk.
  • Fail to see unintended consequences in proposed corrective actions.
  • Fail to share lessons learned with employees and other facilities.
  • Fail to assign responsibility to implement corrective actions.

That’s quite a list. I don’t think I’ve seen any organization with all these problems. But I have seen all of these problems at least once in various organizations.

Most Frequent Problem

What do you think? What are the most common problems in general? At your facility?

Vote on the top five problems in general

The top five I’ve seen (in no specific order) are:

  • Focusing on blame.
  • Use the same old corrective actions.
  • Look for evidence that proves what they think caused the incident (confirmation bias).
  • Never had any root cause analysis training.
  • Using 5-Whys.

If your list of root cause analysis and incident investigation problems is too long, we can help you cut the list down.
