The study of design processes has evolved since the 1960s and has resulted in the development of design methodology. Many themes of academic research reflect the concerns of the ‘Design Methods’ movement with the development of systematic procedures for the overall management of the design process. The design process has been performed in various fields of design practice. In academic research, the design process was defined and identified as a systematic method of creativity in order to solve design problems. Designers have developed design processes through design practice for many years. There are also many theoretical descriptive design processes, which have been developed by academic researchers. How can a design process be successfully applied within a design project? and what is the function of a design process when used in a design approach? To answer these questions, this research examines the backbone of design aspects which should be performed adequately in the design process. It is necessary that the basic theories behind design processes should be understood in order to verify exactly the roles and functions of any new systems. The aim of this study is to investigate and appreciate design processes more fully, and to gain a greater understanding of the multi-disciplines encountered when defining a new design process.
