図の背後にある意思決定を読み解く。
01
Use structured 6M categories with top and bottom ribs to balance the diagram
02
Include second-level sub-causes for high-risk contamination paths
03
Pin categories to fixed sides and order for stable layout
Reuse for any purity-critical metal powder or vacuum process defect analysis; adapt categories and causes to the specific contamination source.
