Root cause analysis

root-cause-analysisThe aim of root cause analysis is to identify the factor(s) that resulted in one ore more past events. Often the event is unwanted and by identifying the root cause it is possible to prevent the event from happening again. There are several tools that can be used for identifing root causes. I often start with Process Mapping (PM) in combination with preparing a Thought Map (TM) or A3 in order to structure the problem solving. Depending on the problem I use various tools like Fishbone diagram / Cause and effect diagrams, Factor analysis and Pareto analysis.
