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

Benefits of Cause and Effect Diagram Making diagram is educational in itself Outline relationship Note what samples need to be taken

Guide for discussion Causes are actively sought and results written on diagram Appropriate data collected - no time wasted Shows level of technology
