The document discusses engineering design and the engineering design process. It describes the engineering design process as iterative and involving problem identification, research, specifying requirements, generating and evaluating concepts, and prototyping, construction and testing. The engineering design process can be either prescriptive, providing an exact systematic process, or descriptive, providing a less formal description of typical activities.

- 1. Revised by S.P. Chew (2009)
- 2. By the end of this chapter, you should: Understand what is meant by engineering design. Understand the phases of the engineering design process. Be familiar with the attributes of successful engineers. 2
- 3. Engineering design is the process of devising a system, component, or process to meet desired needs. It is a 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. 3
- 4. What is a design process? Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing, and evaluation. 4
- 5. Prescriptive exact process or systematic recipe, for realizing a system Algorithmic in nature and expressed on flow charts with decision logic Descriptive Less formal, describing typical activities involved in realizing designs with less emphasis on exact sequencing. 5

- 8. Is this prescriptive or descriptive? 8
- 10. What is the value of the design process? How much does it cost to correct problems as process proceeds? 10

- 13. Engineering design is an iterative process. Design problems are open-ended with many potential solutions. Design processes represent best practices for realizing a system. Design processes may be prescriptive or descriptive. 13
