Question 1

What is Configuration Management?

Accepted Answer

Configuration Management is the PLM discipline that answers the question: 'which version of the product did we ship to which customer, and what is in it?' It governs variants (different flavors of the same product line), options (customer-selectable features), and effectivity (the date or serial number at which a change applies). Configuration management ensures the as-shipped configuration of a specific unit — including the precise revision of every component — is recoverable years later for service, recall, audit, or regulatory inquiry.

Question 2

Why does Configuration Management matter?

Accepted Answer

For complex products sold into many markets — a tractor, a vehicle, an aircraft, a medical device — configuration management is the difference between being able to service what you sold and not. It is also where most regulatory exposure lives: a product configuration that was legal in 2024 may be non-compliant under the 2026 regulatory regime, and only configuration management makes the answer auditable. As the EU Digital Product Passport rolls out across batteries, textiles, electronics, and construction products, configuration management becomes a regulatory artifact rather than an internal one.

Question 3

How is Configuration Management used in practice?

Accepted Answer

In a defense program, CM establishes a PDR (Preliminary Design Review) baseline that locks the requirement set and top-level design; every subsequent Engineering Change Request is assessed against that baseline, recorded in the CM system with rationale and impact, and the as-built configuration record delivered at program completion must match the contract baseline. The CM audit trail is what allows a program office to answer "what exactly is in unit 47?" years after delivery.
