Why-Why Diagram
A why-why diagram is an extension of the 5 Whys approach where they are similar in that they both ask the same Why question multiple times. However, a why-why diagram is used to identify the root causes of a problem when there are multiple factors to consider. There may be multiple answers at each stage, and each of these answers need to go through a separate process of the why-whys analysis. #WhyWhyDiagram
