Managing Engineering Change Orders and Delegation Limits in Manufacturing
Delegating engineering change authority by financial limit and technical classification eliminates plant line stoppages while preserving configuration control.
Configuration Management
Meaning
Systems engineering practices maintain consistency of product physical attributes and performance parameters with underlying design documentation throughout an industrial lifecycle. Through configuration management, technical baselines are formally recorded so that modifications to tooling or assembly software follow documented review procedures. The governance extends across prototype builds and full volume manufacturing, stopping only when items leave active factory control.
Baseline Control
Structural changes during low rate initial production require controlled documentation to prevent unverified revisions from reaching the assembly floor. When engineers adjust a component dimension during pilot trials, configuration management mandates that drawings and bill of materials revisions update concurrently before machine retooling begins. Uncoordinated alterations create mismatches between physical tooling and digital files.
Audit Rigor
Physical audits verify that shop floor assemblies match released engineering drawings down to fastener specifications and firmware versions. Discrepancy checks during pre-production runs quantify how effectively drawing changes propagate across suppliers. When prototype assemblies drift from approved engineering revisions, scrap rates rise sharply during production scale-up because automated pick-and-place systems expect identical physical geometry.
Yield Impact
Unit production yields depend on locking specifications before committing to high volume tooling dies. Premature sign-off without demonstrated process capability forces field modifications and expensive mold retrofits.
