Quoted from The Engineering Design Process (Ertas,2nd Edition):
Possibly the most definitive, and certainly the most applicable, interpretation of the meaning of design for engineering students is that promulgated by the Accreditation Board for Engineering and Technology (ABET) stated in the Criteria for Accrediting Programs in Engineering in the United States,1995-96 Accreditiation Cycle:
Engineering design is the process of devising a system, component, or process to meet desired needs. It is the decision making process (often iterative), in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation. The engineering design component of a curriculum must include most of the following features: development of student creativity, use of open ended problems, development and use of modern design theory and methodology, formulation of design problem statements and specifications, consideration of alternative solutions, feasibility considerations, production processes, concurrent engineering design, and detailed system descriptions. Further, it is essential to include variety of realistic constraints such as economic factors, safety, reliability, aesthetics, ethics, and social impact.
