For a long time I was looking for a better way to provide root cause analysis. More sophisticated than the 5-Whys, but not that compilicated and elaborate as the Ishikawa. And hereby I came across with an enhanced version of the regular Cause-Effect approach.
It’s again a graphical approach which combines simplicity and logic. It’s especially useful for situations in which multiple goals are affected.
The way to evaluate root-causes using the enhanced cause-effect is my preferred way. And that’s due to two reasons. First, it’s rather progressive and can be driven alone or in groups. You achieve quick results without spending too much effort into nasty categorizations or simplifications. Second, in it’s final stage provided as a diagram, it can be quickly and fully understood. You do not need verbose explanations how to read it or why some things have been dropped.
Stay tuned and be inspired.
