Another definition of design is planning to manufacture an object, system, component or structure. Thus the word “design” can be used as a noun or a verb.

American scientist, and Gerhard Pahl and Wolfgang Beitz, two German engineering design theorists. According to the rationalist philosophy, design is informed by research and knowledge in a predictable and controlled manner. The action-centric perspective is a label given to a collection of interrelated concepts, which are antithetical to the rational model. Substantial empirical evidence supports the veracity of this perspective in describing the actions of real designers. Like the rational model, the action-centric model sees design as informed by research and knowledge.
