It arose in the Department of Defense DoD when it was realized that a number of new defense products were being designed without any thought given at the time of design to whether the design was manufacturable. Lack of consideration of manufacturability led to many revisions at a late stage when shortcomings of the design were discovered by the factory. From this came the notable study of projects in 13 companies that led to a report of the Institute of Defense Analyses 1 in which the first definition of concurrent engineering was given Concurrent engineering is a systematic approach to the integrated concurrent design of products and their related processes including manufacture and support. This approach is intended to cause the developers from the outset to consider all elements of the product life cycle from conception through disposal including quality cost schedule and user requirements. Thereafter the concept was given currency in many ways. DoD projects came to insist on adherence to CE principles contractors had to demonstrate how they would take into account the concerns of This work was funded in part by DARPA grant number MDA-972-91-J-1022 .
