Cause & Effect (Fishbone)Description

Primary function is to identify and organize possible causes of a specific effect and then to isolate root causes. Reference to “Possible Causes” because in all cases you must test whether your hypothesized causes are real – and whether enhancing or reducing them will create the outcome you want.

Cause & Effect (Fishbone)1st Why = 1st Arms

D4 - The 1st Why will be forwarded to the 1st Arms of the Cause & Effect Diagram

The Problem Title is pulled forward from the Cover Page

D4 - The 2nd Why will be forwarded to the 2nd Arm/s of the Cause & Effect Diagram

Cause & Effect (Fishbone)2nd Why = 2nd Arms

D4 - The 3rd Why will be forwarded to the 3rd Arm/s of the Cause & Effect Diagram

Cause & Effect (Fishbone)3rd Why = 3rd Arms

D4 - The 4th Why will be forwarded to the Cause & Effect Diagram. It will appear on the left, according to the Failure Mode you have selected.

Cause & Effect (Fishbone)4th Why = Root Cause

D4 - The 5th Why will be forwarded to the Cause & Effect Diagram. It will appear on the left, according to the Failure Mode you have selected.

Cause & Effect (Fishbone)5th Why = Detection
