Engineering Change Order (ECO)

What is Engineering Change Order (ECO)

An Engineering Change Order (ECO) is a formal document used to authorize, communicate and track approved changes to a product, design, engineering specification or related process. It typically records the reason for the change, affected items, required actions, approvals and implementation details to ensure changes are properly controlled and traceable.

Key Features

• Change Documentation: Records the details, reason and scope of an engineering change.

• Approval Workflow: Routes proposed changes through designated review and approval processes.

• Version Control: Tracks revisions to designs, specifications and related documents.

• Impact Assessment: Identifies products, processes, documents or systems affected by the change.

• Change Tracking: Maintains a history of changes from initiation through implementation.

• Role-Based Access: Restricts change-related information and actions to authorized users.

• Audit Trail: Records approvals, modifications and other activities for traceability.

Benefits

• Improves Change Control: Provides a structured process for managing engineering changes.

• Reduces Errors: Helps ensure approved changes are accurately documented and implemented.

• Enhances Traceability: Maintains a clear history of changes, reviews and approvals.

• Supports Collaboration: Keeps engineering, quality, production and other teams aligned.

• Strengthens Compliance: Provides documented evidence of controlled change processes.

• Improves Document Accuracy: Helps ensure teams work with current designs and specifications.

Conclusion

An Engineering Change Order provides a structured and traceable way to manage changes to products, designs and engineering processes. By documenting changes, approvals and implementation details, it helps organizations maintain control, accuracy and consistency throughout the engineering change process.
