What is the difference between DFX and engineering design?
As stated before, the scope of DFX is broader and more inclusive than regular engineering design. By utilising the design principles within the various areas (for example, DFM and DFA), the DFX methodology increases the value while reducing the costs of products.
What is DFX and how does it work?
Issues in the traditional engineering design process are usually identified and rectified after the design phase. Correcting these problems can prove extremely costly in many cases. DFX shifts the addressing of these issues to an early design stage, which saves money as well as time.
What are the different types of DFX?
The “X” that stands for excellence can be substituted with a few letters to address a certain sub-section of DFX. These categories include manufacturing (DFM), assembly (DFA), quality (DFQ), supply chain (DFSC), etc. Designers improve a product’s design in all these areas by implementing certain design principles in the process.
What is design for Excellence (DfX)?
Some other salient characteristics of DFX that are quite self-explanatory are as follows: Design for excellence is an all-encompassing philosophy that provides design guidelines for all aspects of a design and production process. The “X” that stands for excellence can be substituted with a few letters to address a certain sub-section of DFX.

When was the term "design for X" first used?
The term “design for X” first made an appearance at the Keys Conference in 1990 and in the AT&T Technological journal. The papers even suggest that the two authors were not aware of each other, showing that the movement towards the same goal had started independently.
What is design excellence?
Design for excellence is an ever-evolving philosophy of a set of principles in design and manufacturing. It adopts a holistic and systematic approach to design, focusing on all aspects of a product – from concept generation to final delivery.
What is DFX in design?
Design for Excellence (aka Design for X, DFX) is a systematic approach to achieve a targeted objective. X represents targeted objectives or characteristics of product or process. DFX comes under the topic of DFSS which requires a cross-functional team approach with the involvement of stakeholders.
What is DFM in manufacturing?
Design for Manufacturing (DFM) deals with steps for improving manufacturing process to make a good product with reduced manufacturing cost. Product design can be optimized to achieve this goal.
What is DFX in design?
Design for Excellence or Design For Excellence ( DfX or DFX ), are terms and expansions 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 .
Why is user focused design important?

However, in case of capital goods design for ergonomics is needed to ensure clarity, simplicity, and safety between the human-machine interface.
What is label design 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.
What is logistics design?
Design for logistics covers issues along supply chain partners (i.e., legally independent firms) but is by its means closely related to the design for assembly guidelines. In academic research, design for logistics is tangent to the strategic alliances, supply chain management, and the engineering part of new product development. For example, Sanchez and Mahoney (1996) argued that product modularity (i.e., how physical sub-systems of a product are sub-divided through interfaces; also called product or system architecture), and organizational modularity (i.e., how organisational entities are structured), depend on each other, and Fixson et al. (2005) found that the relationship between product architecture and organisational structure is reciprocal in context of early supplier involvement during the system design or respectively concept phase of the Product development process.

What is DFT in engineering?
DFT (Design for Test) : This consists of both design and verification of test-ability features that are added to the design. These becomes highly useful for both functional and structural testing of the chip in the validation phase. A DFT engineer would normally work on JTAG design, Scan chain insertion, scan simulation and compression, stuck-at and transition fault modelling, Memory BIST techniques, ATPG test generation etc. He/She would work close with physical design engineers and RTL design engineers to ensure all of this happens. He would also get a lot of experience in silicon debug as some of these needs to work in silicon before anything else can be validated. In terms of career, I think there is opportunity to start with design/verification of some of these techniques and grow towards handing these are a system architecture. The career path might be more aligned to backend/physical design and would have to deal with complexities of newer technologies while not needing to be aware of a functional domain/architecture (which a front end design/verification engineer needs to)
