Use Cause and Effect diagram EFFECTIVELY...

To successfully build a cause and effect diagram:

 - Build a Cause and Effect diagram successfully:
 - Be sure everyone agrees on the effect or problem statement before beginning
 - Be succinct
 - For each node, think what could be its causes. Add them to the tree
 - Pursue each line of causality back to its root cause
 - Consider grafting relatively empty branches onto others
 - Consider splitting up overcrowded branches
 - Consider which root causes are most likely to merit further investigation
