Abstract
The paper discusses how technological convergence, manifested in increased mobility in organisations, changes the way purchasing organisations buy and use telecommunications and IT systems. The aim of the paper is to analyse how the implementation of mobility in firms is linked to changes in the relationships between units within the buying centre, between the buying centre and supplying organisations, and to some extent also between the buying centre and its customers. The study builds on interviews with purchasing functions in 61 small-, medium-sized and large organisations in different industries. The concept of mobility is discussed and defined. Industrial network conceptualisations, loose coupling theory and a buying centre model constitute the theoretical framework. Results indicate that management plays a more central role in the buying centre when major IT and telecom contracts are signed. The interviews also indicate few large changes in the exchange relationships with supplying organisations as a result of the implementation of new system solutions for increased mobility.
