The scenario
A sputtering target manufacturer investigates recurring porosity and density deviations in formed blanks to identify root causes before corrective action.
What is in this drawing
Read the decisions behind it.
01
Select six standard cause categories (Man, Machine, Method, Material, Measurement, Environment) and pin top/bottom ribs for balanced layout
02
Attach second-level sub-causes under each primary cause to capture actionable root causes
Use for root-cause workshops or defect investigations when sputtering target blanks show density below specification or porosity indications in ultrasonic testing.
