What is the relation between concurrent engineering and DFMA?

Answer 1

'Design For Manufacturability & Assembly 'is the process of proactively designing products to (1) optimize all the manufacturing functions: fabrication, assembly, test, procurement, shipping, delivery, service, & repair, AND (2) assure the best cost, quality, reliability, regulatory compliance, safety, time-to-market, and customer satisfaction'.

Concurrent Engineering is "A systematic approach to the integrated development of a product and its related processes-from conception to disposal-that emphasizes response to customer expectations and embodies team values of cooperation, trust and sharing in such a manner that decision making proceeds with large intervals of parallel working by all life‐cycle perspectives, synchronized by comparatively brief exchanges to produce consensus"

The above definitions are self explanatory on the difference between DFMA & CE.
