Abstract:A quality design is, in part, a design for a quality product. A quality design also incorporates manufacturability, prevention of failures, and other aspects influencing the value of the designed product. Loss of quality of the design can be defined as a cost--to the designer, the manufacturer, the vendor, the user, or society--when the product built from the design fails to meet an intended goal.
The knowledge available to designers, and the forms in which knowledge is recorded, has a substantial impact on how effectively design decisions are made. Methods for reasoning about usefulness of knowledge intended to support design are developed, and two measures of usefulness are introduced: flexibility and coherence of the knowledge.
A clearer understanding on the part of design tool developers of how a tool will be used in design (that is, how engineers do design) will lead to better fit between design tools and the needs of decision-makers. The principal paradigm in engineering design is to acknowledge the complexity of the full problem, but to attack the simplest expression of the problem which will still yield the useful result of advancing the design.
