Abstract: The objective of this paper is to delineate the interrelationship between the enablers of a telecom service supply chain in the Indian context. Interpretive structural modelling has been explored to find the interrelationships between the enablers. Elicitations of the experts from industry and academia have been explored in this regard. Based on the interrelationships matrices named: 1) initial reachability metrics; 2) final reachability metrics have been framed. Diagraph has been developed and further it has been transformed to ISM. The hierarchy of various enablers has been established based on the outcomes of the final reachability metrics and finally driving power-dependence diagram has been developed to categorise the enablers in to four clusters. The results indicated that there exists higher degree of interrelationship between the enablers. The paper is concluded with action plan and scope for future work.
