Engineering Change Order (ECO)

An engineering change order (ECO) is an official document describing the changes required in an existing process or product, often outside LN (PLM). ECOs are proposals that often needs to be approved because of implications in Procurement (BOM), Factory work (Routing), and Quality. The document contains a set of instructions for making changes to several objects from the areas of engineering or production. The conditions under which these changes become effective and the release status are also defined in an ECO.
