In ECMS, what distinguishes an Engineering Change Request (ECR) from an Engineering Change Order (ECO)?

In ECMS, changes start with a proposal, not an instruction to act. An Engineering Change Request is the formal proposal to alter a product or process. It captures the need, scope, affected items, and potential impacts, serving as the initiating record that triggers review and decision-making. The approved action to implement that change is documented in an Engineering Change Order, which is the actual, actionable directive used to update engineering drawings, bills of materials, procedures, and manufacturing instructions. It’s the authorization that moves the change from idea to reality. So the statement that the ECR is a proposal to change a product or process is the correct distinction: the ECR initiates the change, while the ECO carries out and documents the implementation. The other options describe the ECO being the proposal or being an archival record, which isn’t accurate—the ECO is the implementable directive, and archival records may exist after completion but are not the ECO itself.
