Compare and detect any engineering changes made between the ECO part received from the customer and the part to be updated (the work part, which could be a previous ECO or a master part). These changes can then be edited, and the model consequently updated.
In a typical system development cycle, the specification or the implementation is likely to change during engineering development or during integration of the system elements. These last-minute design changes are commonly referred to as Engineering Change Orders (ECOs) and affect the functionality of a design after it has been wholly or partially completed.
