Why Systematic Design Engineering?

Design engineering is different from other more artistic forms of designing because on one hand it is more constrained by the engineering sciences, economics and other factors, but on the other hand it has more possibilities for abstract modeling in the conceptual phases. Creativity is essential, but in many cases not sufficient to explore the many possible candidate solutions. A more systematic and methodical approach can help to overcome many of the problems that arise during conceptualizing in design engineering. Use of appropriate methods to enhance the search for solutions can expand the solution field. A systematic approach based on engineering design science has been shown to enhance understanding, good record-keeping, and traceability for the design process. Several grounded theories are reviewed and brought into mutual context, they refer to memory and thinking operations, expertise, human action modes, and competencies. The discussion reveals a need for specific instructions for a methodical and systematic engineering design procedure, when the design problem is seen as non-routine, and expertise is lacking.
