What Is an Engineering Change Order (ECO)?
An Engineering Change Order (ECO) is a formal process to document, propose, review, approve, and implement changes to files, parts, or assemblies within your product design or manufacturing process.
In Bild, ECOs ensure that changes are controlled, traceable, and fully auditable across your team.
Common reasons for ECOs include:
Design revisions or updates
Part replacements or material changes
Supplier-driven updates
Quality or compliance corrections
Using ECOs helps teams avoid miscommunication, reduce errors, and maintain accurate records of why and when changes were made.
