Engineering Change Notice Definition An Engineering Change Notice (ECN) or Engineering Change Order (ECO) is a document that authorizes and records design changes throughout the prototyping and life-cycle phases of a product. This documentation contains the justification for changes that are made to a component or system once the initial design is complete. It also forces changes to be approved by the relevant authorities (often the project manager). An ECN must contain at least the following information: (Ullman 2009) Identification of what needs to be changed. This should include the part number and name of the component and reference to the drawings that show the component in detail or assembly. Reason(s) for the change. Description of the change. This includes a drawing of the component before and after the change. Generally, these drawings are only of the detail affected by the change. List of documents (and in industry, the departments) affected by the change. The most important part of making a change is to see that all pertinent groups are notified and all documents updated.
