| Summary: | Delays and conflicts (D&Cs) are adversely affecting the performance of construction projects. They have separately been addressed by many authors but the mutual relationship among them is still a key grey area. Therefore, this study aims to explore this hidden relationship. Literature was reviewed to identify the previous ranking of D&Cs causes to develop a global ranking and to explore other hidden aspects of mutual relationships. Data were classified through Jenks optimization that resulted in the identification of, the top five causes of D&Cs in a global perspective and commonality among them. Among the top five identified global causes of D&Cs, the common causes are; (1) financial problems on behalf of the owner, (2) Change orders/ Variations, and (3) Lack of communication/ Poor relationship. Such exploration of hidden relationships among D&Cs will not only improve construction management strategies but will also define new pathways for future research to secure project success parameters.
