Why Use the Fishbone Diagram Template?
The template provides a simple, yet powerful structure for Root Cause Analysis (RCA) by guiding the team through the following process:
Define the Problem (Head): The "head" of the fishbone clearly states the specific Problem (Effect) to be analyzed, ensuring everyone is focused on the same issue.
Identify Major Categories (Bones): The "major bones" branching off the central spine represent the main categories of causes. Common categories often used in manufacturing are the 6 Ms: Manpower, Methods, Machines, Materials, Measurement, and Mother Nature (Environment).
Brainstorm Sub-Causes (Smaller Bones): Under each major category, the team brainstorms detailed sub-causes and potential root issues. This systematic approach prevents the team from jumping to surface-level conclusions.
