CAUSE AND EFFECT DIAGRAMS (Fishbone Diagram)Used in brainstorming session to help identify the causes of qualitylosses. This diagram is particularly useful after the flow chart and thePareto diagrams have been developed.
Step 1: Decide on the quality characteristic {e.g. Reduction of wobbleduring machine rotation}Step 2: Set up the fish bone backboneStep 3: Identify main factors causing effect {e.g. Workers, Materials,Inspection, Tools}Step 4: Add Cause to each branch
