Root Cause Analysis - 5 whys - Five Whys - Genchi Genbutsu philosophy
Widgeter Mk. II
Gary has noticed the widgets coming through his station are defective.
Gary reports the problem to his boss, and they decide to perform a quick "5 Whys" analysis, along with a couple of Gary's co-workers.
The team articulates the problem and builds a linked chain of causation back to the root cause: the secondary widget punchers aren't being cleaned enough.
The team uses Storyboard That to map out a new protocol for widget puncher maintenance that is easy to understand and follow.
Gary's boss uses the storyboard as part of her report to upper management, reassuring them that the source of the defects has been eliminated.
There are no more defective widgets! The manufacturing process has been improved, and everyone is ready to get back to making the product.
