Getting to the true root cause of the problem is a skill set. Its a trained skill set that is used in the quality or production departments of pharma companies to name just one.
The skill can be also applied to business operations but it rarely is.
The result of not applying this skill set is to blame John or blame the accounts department, blame someone or else implement a checklist after the horse has bolted.
Treating the root cause of the problem is the only way to prevent repeated expensive errors downstream.
Have a 7 minute listen to a real life situation I faced very recently.
