Engineering Change Order
An Engineering Change Order (ECO) is a formal document that outlines changes to an existing product design, specification, or process, typically initiated by a manufacturer or engineer to address quality issues, regulatory compliance, or performance enhancements. ECOs are used in Product Lifecycle Management (PLM) systems to track and manage changes throughout the product development lifecycle.
Why it matters
An Engineering Change Order (ECO) is crucial for PLM professionals and manufacturing engineers as it ensures that all stakeholders are informed and updated on changes to products or processes, reducing errors, rework, and costs associated with implementing changes.
