There are many different documentation tools for root cause analysis.

Some of the most common are:

  • Fishbone diagram
  • 5 – why
  • Cause-and-effect diagram

IDCON suggest using a cause-and-effect diagram, the key reasons we like this method are:

  • The cause-and-effect diagram helps the problem solver(s) to "divide and conquer" the problem. It allows the problem solver(s) to focus on one ‘branch’ of the diagram at a time. Humans are very poor at thinking at many things at one time (that is why you are driving your car, you turn down the volume of the radio when you are trying to find an unknown street sign or exit)
  • The cause-and-effect diagram is the only way to explain and research the cause and effect relationship in an even chain. The other diagrams don’t do this well.
