A process is the logical set and sequence of steps to achieve specific outcomes from specific inputs.
The purpose of the Why-Why Diagram is to enable individuals and teams to creatively explore and consider numerous causes of a problem. It helps individuals achieve divergent thinking.
Below is an example of a Why-Why Diagram developed to analyse low operating profit. Since each step is a divergent process, a convergent process is required to determine which of the causes is important.
Steps to follow
1.Develop
a problem statement or Focus.
2.Explore
possible causes of the problem (or reasons for addressing an opportunity) by
asking “Why?”
3.For
each possible cause (or reason) again explore possible causes for this lower
level problem by asking “Why?”. The
answers to the questions “Why” are the causes of the problem.
