Design Process Planning from a Viewpoint of Progressive Nature of 13 Copyright c

Design process planning has become more important toward competitiveness in a market under the various challenges of product development. This trend demands not only relative or qualitative but also quantitative planning scheme. This paper firstly reviews state of the art of design process planing and shortcomings of conventional approaches, and investigates the characteristics of design process through a case analysis of student formula project. Progressive nature of knowledge acquisition that is performed by respective designers and task consistency among designers and teams that is promoted through meeting are focused as key characteristics of design process dynamics. Following this insight, this paper proposes a system of axioms and theories for distinctively defining the meaning of tasks, knowledge, design quality, meeting and overall shape of design process, outlines the perspective of the design process planning methodology based on the formal model, and demonstrates its application to the student formula project
