Engineering Change Order Process (ECO) is the procedure of creating, submitting, and managing a request from engineering to modify an existing product or process. It involves analyzing the situation, requesting permission to alter the current design and/or production, implementing the changes, and providing feedback to the engineering team. ECOs are designed to ensure that any changes made to the product or process comply with quality and safety standards. By developing an effective ECO process, companies can ensure that their products are up-to-date and meet customer requirements.
