The global construction industry is increasingly focusing on project partnering, which requires transforming organizational norms and culture to foster the partnering enabling factors towards project partnering. Successful organizational structures can shape and reflect cultural and behavioral characteristics. Our former article in this journal aimed to identify impacts of the organizational culture, organizational structure, and partnering enabling factors on the partnering activities. Therein the understanding of complex human behavior was crucial for effective research methodology. Positivism and interpretivism approaches were considered effective for addressing above aspects of partnering. A layered approach is used to select appropriate research philosophy and methods, as explained in the Chapter 1 to 4 of the Leading author’s PhD Thesis. The purpose of this article is to summarize Chapters 5 of the collection and analysis of qualitative data, Chapter 6 of the collection and analysis of quantitative data and the Chapter 7 of the thesis recommendations. Thus, mixed methodology research technique was chosen following the philosophy. Accordingly, a questionnaire to distribute among 200 people and semi-structured, open-ended interviews to conduct with 20 participants were prepared as per problem statement. The population and samples calculated using standard sampling techniques, and standard data collection protocols were adhered to. To guarantee the reliability, validity and normality in the study, the advanced statistical tests of Cronbach Alfa, K. Smirnov and Shapiro-Wilk, Kruskal waliis, Chai square, Pearson core relation tests were conducted in conjunction with the relevant statistical programs of NVIVO20 & SPSS26.
