Configuration Management (CM) keeps the authorised product definition and the real product aligned throughout its life. It connects requirements, drawings, BOMs, software, materials, manufacturing instructions, special processes, inspection, test, approved changes, concessions and the as-built record.
Document control is not the same as configuration management
Document control can tell you that Drawing 12345 is at Revision F. CM should allow you to determine which revision, BOM, software, process specifications, approved changes and deviations apply to a particular serial number or lot — and whether the physical product agrees with that record.
Baselines
Complex programmes may use a functional baseline (what the product must do), an allocated baseline (how requirements are allocated to configuration items) and a product baseline (the detailed definition used to build, verify, deliver and support the product). The exact baseline structure should be appropriate to the organisation, product and contract.
AS9100 alignment
AS9100 clause 8.1.2 is the central CM requirement. CM also interacts with documented information, design and development changes, external-provider controls, production, identification and traceability, release, nonconforming outputs and first article inspection. This app is guidance and a project aid; customer, regulatory and contractual requirements always take precedence.
