Quality can't be inspected in. It has to be designed and built in.
No inspection is ever 100% effective — every gate has an escape rate. The way to zero defects isn't more checking at the end; it's removing failure modes earlier in the chain, one stage at a time, until there's nothing left to escape.
01 · DESIGN OUT
Engineer the risk out
Identify and mitigate failure modes before a part physically exists, and trace every feature back to a real customer requirement.
Design FMEA · RM13004Design to Req. · RM13008
02 · PLAN OUT
Make the process incapable of failing
Analyse the process for failure modes and lock in mistake-proofing and a control plan so it produces defect-free parts by design.

03 · PROVE CAPABILITY
Trust the gauge, then the process
Confirm the measurement system is accurate and repeatable, then prove the process is genuinely capable before it runs at volume.

04 · CONTROL
Hold target, minimise variation
Run the process on target with statistical control, feeding live data from production and inspection back into the loop.

Close the loop. Every defect that does escape is driven to permanent root-cause resolution — so it can never recur. 8D Problem Solving · RM13000
