Design
involves solving problems, creating something new, or transforming less
desirable situations to preferred situations. To do this, designers must know
how things work and why. Understanding how things work and why requires us to
analyze and explain. This is the purpose of theory. The article outlines a
framework for theory construction in design. This framework will clarify the
meaning of theory and theorizing. It will explain the nature and uses of theory
as a general concept. It will propose necessary and sufficient conditions for theory
construction in design. Finally, it will outline potential areas for future
inquiry in design theory.
Key words: Design research, design science, design theory, philosophy of design, theory construction
