10.8 Downstream Influence: Design for X

Design for X (DfX) is a term used to describe a series of design guidelines, such as Design for Manufacturing, Design for Six Sigma, Design to Cost, and Design for Test. [10] For example, Design for Test can include inserting probe points on a circuit board. Each of these captures downstream constraints or considerations and propagates them back upstream. Having covered implementation and operations broadly, let’s see what other considerations have been captured under Design for X.

One way to think about the universe of Design for X is in terms of the following list of “ilities,” or attributes of the system that are related to its implementation and operations. The list of 15 “ilities” shown in Figure ...
