The scenario
A sputtering target manufacturer observes unacceptable grain size variation across rolled metal targets, affecting thin film uniformity. The team uses the fishbone to organize potential root causes by 6M categories.
What is in this drawing
Read the decisions behind it.
01
Pin top and bottom categories to keep the diagram balanced
02
Add sub-causes under the most probable root causes
03
Avoid compact shorthand to keep category IDs unambiguous
Use when investigating metallurgical or dimensional non-uniformity in rolled metal products where multiple causal categories must be explored.
