Engineering Change Order
An engineering change order (ECO) outlines new product designs or proposed changes to existing designs and lists all affected parts and assemblies. It will include the reason for the change, documentation, drawings, manufacturing disposition codes, revision details, cost information, and other relevant information. ECOs must be reviewed and approved by internal product teams and their external supply chain partners. The group responsible for reviewing and approving changes is typically referred to as the change control board (CCB).
