Defining the scope of service operations management: an investigation on the factors that affect the span of responsibility of the operations department in service companies

This article deals with the definition of the scope of operations management (OM) in service companies. Operations, in service companies, are often dispersed throughout the organisation and so it is difficult to understand where OM tools and practices can be applied and who should be in charge of their implementation. Starting from the assumption that the actual scope of service operations is influenced by the degree of variety of the offering and of variability of the delivery process, this article analyses three case studies in an attempt to understand whether and why operations, in these companies, include different activities. This article argues that three factors affect the perceived scope of OM, namely: the dominant culture; the existence of industry-specific regulations and the endowment of facilities.
