5.1 Design process

The design process is the transformation of an idea, needs, or wants by stakeholders, consumers or the marketplace, into an artefact that satisfies these needs. Wallace and Blessing made a different angle to systematic design by mentioning two contrasting ways in which design can be approached. The systematic generation of solutions set out by Pahl and Beitz is a problem-orientated approach. Another approach is a more artefact-oriented approach, which is evident in the initial product idea then continually kept through the design process.
5.1.1 Prescriptive or descriptive

There is much literature regarding on how to form the design process. Reading the literature these can be placed into two different categories, these can be descriptive process models (see Figure 1 (appendix A)) and the prescriptive process models (see Figure 2 (appendix A)), both of which are commonly represented by flow diagrams.
The descriptive models attempt to replicate the sequence of occurrences throughout the general design process. The prescriptive models are then built upon these descriptive models in order to guide the designers more efficiently through the design process. Although the prescriptive models are by definition not normally used design practices, many are so generic and well known that they only remain prescriptive to novice design engineers. According to papers the most famous and commonly quoted of these
