ABET emphasizes that design is an iterative decision-making process in which natural sciences mathematics and applied sciences engineering are applied to meet a stated objective in an optimal manner. The schematic of this process is as follows Identifying User Needs Concept Development i Synthesis 4 Optimization 4 .

All Rights Reserved. One can rightfully argue that design is not such a neat sequential process as is shown in the figure. Today product development teams have multidisciplinary members who concurrently work on several aspects of design without being totally restricted by any sequential approach. Thus our focus in this Part I will be on concurrent design and engineering analysis. In Chap. 2 conceptual design is discussed as the first step in the engineering design process. Customer-needs evaluation concept development including industrial design and identification of a viable product architecture are the three primary phases of this stage of design. Several engineering design methodologies are discussed in Chap. 3 as common techniques utilized in the synthesis stage of the design process. They include the axiomatic design methodology developed by N. Suh . the Taguchi method for parameter design as well as the group-technology GT -based approach originally developed in Europe in the first half of the 20th century for efficient engineering data management. In Chapter 4 computer-aided solid modeling techniques such as constructive solid geometry and boundary representation methods are presented as necessary tools for downstream engineering analysis .
