A quality and engineering governance concept defining controls used to plan, verify, and maintain compliant product development and production. It governs requirements capture, process control, documentation, and objective evidence used to demonstrate conformity to defined standards. It does not substitute for technical performance and requires rigorous execution and traceable records to be effective. It materially affects safety, reliability, and manufacturability by reducing variation and improving defect prevention and detection. The concept is generally stable, though standards and accepted methods are revised as technology and industry practices evolve over time.

Principle

Establish baselines, identify configuration items, control and authorize changes, maintain status accounting, and perform configuration audits to ensure integrity.

Demonstration

Example: Release of a baseline wiring-harness drawing for an aircraft, controlled revisions with revision numbers, serialized hardware tracking on builds, and verification checks before flight testing.

Misapplication

Treating configuration management as mere document filing or ignoring software and firmware versions in embedded systems, leading to mismatched configurations in production.

Consequence

Effective configuration management ensures reproducibility, interchangeability, maintainability, and supports certification and safe operation of produced items.

Reversal

An uncontrolled state where production units diverge from the authorized documentation, resulting in nonconformances, safety risk, and failed audits.

Boundary

Focuses on product and process configuration under engineering control; excludes management of business records unrelated to product definition or immediate line-level production scheduling.

Semantic Tension

Overlaps with product lifecycle management (PLM) and quality management systems; CM specifically enforces baselines, identification, and controlled change for configuration items.

Synthesis

Configuration Management in manufacturing is the system of baselines, identification, controlled change, and records that guarantees the product built matches the authorized design and associated processes.
