Abstract:
Most of the knowledge in construction industry is tacit rather than explicit, and its sharing is imperative for enhanced project performance. Tacit Knowledge Sharing (TKS) is heavily influenced by an array of human factors such as behaviour, attitude, skills, experience, personal contact and interaction. These factors interact in multiple ways resulting in positive as well as negative loops for TKS, leading towards complexity. The purpose of this study is to examine the role of TKS in developing countries and thereafter, develop a System Dynamics (SD) model for addressing aforementioned complexity. The study delineates the interrelations between nineteen shortlisted contributing factors of TKS using systems thinking and causal loop diagram (CLD). In total, CLD encompassed four reinforcing and two balancing loops. Furthermore, CLD was used to develop a SD model that contained four stocks. An additional stock named as TKS was incorporated to visualize the combined effect of all stocks. The model was simulated over a period of five years and results indicated increase in TKS efficiency under the defined system and hence improvement in construction project performance. The resultant CLD and SD model reflect the systems thinking and behaviour over time for TKS in construction. The study adopts a novel methodology in form of SD for holistically addressing the construction culture to be favourable for TKS and thereby improving construction project performance.
