Description of the Fishbone, otherwise known as Ishikawa Diagram: 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) 1 st Why = 1 st Arms D4 - The 1 st Why will be forwarded to the 1 st Arms of the Cause & Effect Diagram The Problem Title is pulled forward from the Cover Page
D4 - The 2 nd Why will be forwarded to the 2 nd Arm/s of the Cause & Effect Diagram Cause & Effect (Fishbone) 2 nd Why = 2 nd Arms
D4 - The 3 rd Why will be forwarded to the 3 rd Arm/s of the Cause & Effect Diagram Cause & Effect (Fishbone) 3 rd Why = 3 rd Arms
D4 - The 4 th 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) 4 th Why = Root Cause
D4 - The 5 th 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) 5 th Why = Detection
