engineering change order. A formal document that has been signed off by the affected departments and authorizes product definition changes to a drawing, bill of material or routing. It often ties to system planning, scheduling and cost functions by specifying an effectivity date for the items included.
Energy Conservation Opportunity. This term is widely used to represent any energy efficiency project that will reduce energy expenditures. Similar acronyms include FIM (facility improvement measure), ECM (energy conservation measure).
Engineering Change Order. A change management system designed to track changes made to production standards (routing and bill of material). Also called Engineering Change Requests (ECR) and Engineering Change Notifications (ECN) or Engineering Change Management (ECM). ECO systems typically affect material planning, inventory, purchasing and other departments within an organization.
(n) See engineering change order.
engineering change order. (n) A document that begins the process for making changes in a design. Normally, the ECO will be documented in an engineering change note (ECN). A copy of the engineering drawing is attached to the order, with sketches and a written description of the change. A reference number is given to the change order so that it can be traced within the organization.
Engineering change order. an alteration made to an AVL or BOM, such as the replacement of one component by a substitute component. Any changes should be prepared, approved and incorporated promptly and correctly to minimize problems. Changes often vary in complexity and urgency, but can have a ripple effect. Any ECO should be documented on a blank form or template that contains key information, such as a description of change, a reason for the change, the type of change and the implementation date (e.g., immediate action or implement when possible).
Engineering Change Order. The second step in the procedure to change specifications. CableLabs posts ECOs to Web site EC table and ECO page (with indication of ECO Comment Deadline). CableLabs issues ECO announcement to an Announcement mail list and working group mail lists (with indication of ECO Comment Deadline). DOCSIS, CableHome, OpenCable and PacketCable all utilize a similar process.
A means for requesting engineering changes.
