Design process

Substantial disagreement exists concerning how designers in many fields, whether amateur or professional, alone or in teams, produce designs. Design researchers Dorst and Dijkhuis acknowledged that "there are many ways of describing design processes", and compare and contrast two dominant but different views of the design process: as a rational problem-solving process and as a process of reflection-in-action. They suggested that these two paradigms "represent two fundamentally different ways of looking at the world – positivism and constructionism ". The paradigms may reflect differing views of how designing should be done and how it actually is done, and they both have a variety of names. The problem-solving view has been called "the rational model", "technical rationality" and "the reason-centric perspective". The alternative view has been called "reflection-in-action", "co-evolution", and "the action-centric perspective".
