Design for Excellence (DFx) Design for Excellence (Dfx)

Typically 70 to 80% of a product’s cost is locked in at the earliest stages of product development.  It is at this point that a product’s configuration begins to emerge and decisions begin to be made regarding the materials and manufacturing processes to be involved.  Much of the potential for product quality is also locked in with these decisions. 

Concurrent engineering strategies such as Design for Manufacturing, Assembly, Supplier Costing, Test and Servicing focus upon creating product design enviroments where these historically downstream considerations are moved to the earliest stages of product design and become influential in the design process itself.

This same approach applies equally to other functional areas within organizations.  For example, business systems should be designed with great attention to and consideration of the variation, tolerances and capabilities of the processes supported.
