DFX
Résumé
Design for excellence (DfX or DFX) is a term and abbreviation used interchangeably in the existing literature, where the X in design for X is a variable which can have one of many possible values. In many fields (e.g., very-large-scale integration (VLSI) and nanoelectronics) X may represent several traits or features including: manufacturability, power, variability, cost, yield, or reliability. This gives rise to the terms design for manufacturability (DfM, DFM), design for inspection (DFI), design for variability (DfV), design for cost (DfC). Similarly, other disciplines may associate other traits, attributes, or objectives for X.
Under the label design for X, a wide set of specific design guidelines are summarized. Each design guideline addresses a given issue that is caused by, or affects the traits of, a product. The design guidelines usually propose an approach and corresponding methods that may help to generate and apply technical knowledge to control, improve, or even invent particular traits of a product. From a knowledge-based view, the design guideline represents an explicit form of knowledge, that contains information about knowing-how-to (see Procedural knowledge). However, two problems are prevalent. First, this explicit knowledge (i.e., the design guidelines) were transformed from a tacit form of knowledge (i.e., by experienced engineers, or other specialists). Thus, it is not granted that a freshman or someone who is outside the subject area will comprehend this generated explicit knowledge. This is because it still contains embedded fractions of knowledge or respectively include non-obvious assumptions, also called context-dependency (see e.g. Doz and Santos, 1997:16–18). Second, the traits of a product are likely to exceed the knowledge base of one human. There exists a wide range of specialized fields of engineering, and considering the whole life cycle of a product will require non-engineering expertise. For this purpose, examples of design guidelines are listed in the following.

Design for Manufacturing
DFM ou Design for Manufacturing ou encore Design for Manufacturability est l'ensemble des règles utilisées en électronique et tout particulièrement dans l'industrie des semiconducteurs afin de concevoir des composants qui puissent être facilement fabriquées. Par facilement fabriquées, on entend avoir un rendement élevé lors des séquences de test. . DFM a donné naissance à toute une série de D for something comme: Design For Testability (DFT) Design For Assembly (DFA) Design For Maintainability (DFMaint) Design For Services (DFS) Pour cela, un sigle générique de DFX a été créé.
Product lifecycle
In industry, product lifecycle management (PLM) is the process of managing the entire lifecycle of a product from its inception through the engineering, design and manufacture, as well as the service and disposal of manufactured products. PLM integrates people, data, processes, and business systems and provides a product information backbone for companies and their extended enterprises. The inspiration for the burgeoning business process now known as PLM came from American Motors Corporation (AMC).
