Telecommunication companies are in a state of transition, going from product focus towards more service focused business approaches, and the development has been ongoing for many years. This paper takes a Product Service Systems perspective on the product-to-service transition process in the telecommunication industry by presenting the case of Ericsson. It is argued that a Product Service System approach would support the co-existence of both products and services, their mutual dependency on each other and thus gain competitive advantages for the company. Further, an Organisational Maturity and Offering Matrix is presented and the Ericsson case is mapped to it.
