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.

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.

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.

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.
