The application of lean management is able to improve construction processes. Unnecessary waiting time, overstaffing and risk uncertainty
are some of the problems that can be eliminated by adopting lean management. Industrialised Building System (IBS) is a sustainable
approach that can be improved construction deliverables with the integration of lean management. However, the adoption or practice
of lean management in productions of IBS component productions is still limited. There are only few studies emphases on the interactions
among key drivers and hierarchy of lean management key drivers model. This study used Interpretive Structural Modeling (ISM) to
interpret relationship of drivers and challenges in integrating lean management in form of ISM based-model and Matrice d’impacts croises
multiplication appliquee an classment (MICMAC). The results from this will improve the adoption of lean management in IBS application.
