A Step by Step Process to Guarantee Success
The real value of the process is that it drives you to find and solve the underlying cause of the issue not just the obvious symptom.
- Step 1: Agree on the Problem Statement
- Step 2: Ask “Why Did This Happen?”
- Step 3: Check – Is This a Root Cause?
- Step 4: Fix the Underlying Cause, and Correct the Symptom
By solving the underlying cause you ensure that the problem does not happen again. This prevents you having to solve the symptom (the problem you currently see) in the future; thus saving you time, money and effort every day.
