Most new mobile services for 3G and beyond are developed by a network of organisations that have to work together to realise access to infrastructure, middleware (such as location based technologies), multimedia content, customer data and customers. This network of organisations and or business units within organisations adds to the value of the service as perceived by the customer. Although much is written about business models, little is known about business models used by networked organisations. Furthermore, proper performance indicators for business models are still under development. Within ongoing research projects, such as Business Models for Innovative Telematics Applications (BITA) and Business for You (B4U) we are designing an instrument to measure the performance of networks in delivering customer value. In the paper we will discuss literature with regard to business models, networked services and performance and propose a measurement instrument.
