The 6M Fishbone Diagram is a pre-structured Ishikawa built for production, manufacturing, and operations teams. Six color-coded branches (Materials, Machinery, Methods, Measurement, Manpower, Mother Nature) with example sub-causes guide fast brainstorming. A clear problem area and step-by-step usage guide help cross-functional groups decompose complex issues into actionable categories and isolate true root causes.
How to Use the 6-Prong Fishbone Diagram Template
Define the problem and scope in the problem area.
Brainstorm potential causes under each 6M branch (Materials, Machinery, Methods, Measurement, Manpower, Mother Nature).
Group and refine sub-causes as they are added to the diagram.
Apply the Five Whys to the top suspected or high-impact items to reach root causes.
Plan actions to address confirmed root causes and track progress.
