Engineering Change Order
A formal document in PLM that records a proposed or approved modification to a product design, including the parts affected, the reason for the change, and the implementation date or effectivity.
Why it matters
In a variant product family, an ECO against a shared platform component must trigger a review of every variant it affects. Without formal ECO traceability across the variant family, platform changes silently break individual variant BOMs.
