Engineering Change Order (ECO)
A formal work authorization that executes an approved change to released product data — updating drawings, BOMs, specifications, and other affected documents to reflect the authorized new design.
Why it matters
The ECO is the audit-trail artifact that proves a change was authorized and executed through the formal governance process, which is required for regulatory compliance in many industries.
