The challenges of choosing the best supplier or IBS manufacturer are dealt with from the perspective of project goals and objectives. Nevertheless, for there are limited guidelines in selecting an appropriate type of IBS for housing projects, by contractor available in Malaysian Construction Industry. Thus, the aim of this paper is to identify the significant decision-making approaches and challenges of decision-making in selecting the IBS types. Data collected via survey in the form of a structured questionnaire from 101 respondents are then analysed using IBM SPSS software. A descriptive analysis highlights the pattern of approaches in decision-making to select the type of IBS for housing projects, the extent of individual employment and organizational experiences toward the decision-making for housing projects in Malaysia, and the significant level of knowledge for IBS contractors when selecting the best type of IBS for housing project. The most frequently used approach in decision-making is ‘Intuition and Experiences’ of which the Middle Manager is found to be the personnel that uses it. Furthermore, the ‘Unclear Project Goals and Objectives’ is the most challenging of decision-making in selecting the IBS types in this study.
