Cross-functional view
How the areas connect
Most quality failures are not contained inside one function.
The defect appears in assembly. The root cause is in the drawing. The real decision was made in purchasing six months earlier. The documentation that should have caught it was written by someone who has since left.
Each of the six work areas above reflects a different zone where these failures occur — machining, supplier interfaces, process stability, early-phase risk, QMS, and knowledge continuity. What makes the combination useful is not that each area is covered individually. It is that quality problems rarely stay inside one of them.
Failure at the interface between supplier communication and internal specification is not a supplier quality problem. It is not a documentation problem. It is both — and fixing only one side produces a report, not a solution.
Over more than 20 years of manufacturing quality work built across these areas — not specialised in one of them — means the diagnostic view follows where the problem actually goes.
