Decision making skills with a wide range of decision scenario are relevant to the members of construction supply chain as decision making processes are essential to be understood in ensuring the success of a building project. Currently, there are likely that few decisional issues in the application of Industrialized Building Systems (IBS) require the invention of a completely new dimension and outlook. There is an increasing use of IBS to substitute conventional construction methods in Malaysia, however, the use of IBS technology is often resisted, apparently on grounds other than simply technological. The aim of this chapter is to present the influence of behavioral economic factors on IBS decision making as perceived by IBS supply chain members in Malaysia. Conclusions are drawn and recommendations are made with respect to the perception of behavioral aspects, socio-economic and IBS technology associated with building projects.
