Abstract

The design process is fraught with a myriad of decision points. The outcome of these decision points is significant in discovering and generating value in the construction project delivery process. Application of a collaborative decision system, such as choosing by advantages (CBA), on these decision points, has been established to enhance value generation by enhancing participation, transparency and respect among stakeholders. However, little attention has been given to identifying strategic considerations for operationalizing CBA application across the design process spectrum. This paper combines knowledge from the case application of CBA, on selected design decisions, with theories on design process management and lean design in identifying these strategic considerations. Significant findings, among others, is the need to stratify the design process into identifiable decision frames to form the basis for applying CBA across the design process spectrum; the use of boundary objects to enhance communication among stakeholders in CBA application in design process; and the need for clearly established project requirements at the project definition phase to provide a sound basis for the CBA process. Findings of this study should provide a practical guide for CBA application in design process towards lean design implementation.
