Description:
Why-Why Analysis is a variation of the Cause and Effect Diagram. Like Cause and Effect Analysis, it can be used to
uncover the root causes of a problem. Also, like Cause and Effect Analysis, the process can be reversed (See: HowHow Analysis) to develop the steps needed to achieve a desired effect.
Directions:
Begin by creating the first box of the diagram at the left side of the page (roughly in the middle vertically.) Place the
&quot;effect&quot; (the observable condition) in this box. Ask the question: &quot;Why?&quot; This is the question at every stage of this
process. &quot;Why is this happening? Why is this the case?&quot; Branch the most obvious answers into the next column to the
right. Then, taking each answer in turn, ask the &quot;Why?&quot; question again and branch those answers into the next column.
This process can be extended as far as necessary to uncover the root cause of the problem. As a general rule, if you
ask &quot;Why?&quot; five times, you will most likely reach the root cause of the situation.
