Better design decision management is possible through the use of lean production planning and control techniques, group decision-making, and knowledge management tools. Central to the success of these tools is the capture and timely management of the design rationale underlying design decisions. This research views design as a collaborative decision-making process, and highlights the need for supporting group technologies. The literature is summarized regarding relevant design processes, decision models and group support systems available to designers. Design viewed as an explicit decision making process is discussed and background research on group decision-making is documented. This paper also explores the benefits of employing design rationale systems to promote quality design assignments, value generation, and team learning among project stakeholders. A need for understanding the interfaces of design process, group decision-making and information technology support is established. A research model is proposed to integrate design rationale management with design process planning and control for the project definition phase of project delivery.
