In the first session about root-cause analysis we have introduced the 5-Whys technique. It has its benefits, but also some severe disadvantages. As one of the most obvious ones the limitation on one root-cause can be highlighted.
In this episode the Ishikawa technique will be introduced. The Ishikawa-diagram could be assumed as the big brother of the small 5-Whys. The Ishikawa covers all the limitations of the 5-Whys and provides a great way to also handle multiple root-causes and more complicated effects. But it also has its disadvantages and pitfalls.
