To start with a quotation from Canty (1987)
CE (Concurrent Engineering) is both a philosophy and an environment. As a philosophy, CE is based on each individual’s recognition of his/her own responsibility for quality of the product. As an environment it is based on the parallel design of the product and the processes that affect it throughout its life-cycle.
It is the provision to the individual of tools to aid their contribution to product quality, as well as the facilitation of the parallel development of product and process design through new methodologies as well as tools which must be primary goals of current research work in CE and design for manufacture (DFM).
