The trade-off between standardisation and customisation is one of the crucial issues in new service development. In this paper, we first review some earlier theoretical works on the formalisation of the new service development process and its impact on firm success. Thereafter, we examine existing theoretical process models for service productisation and discuss their similarities and differences regarding proposed generic design processes. A case study of productisation process in a Finnish KIBS firm operating in internet communications and marketing business highlights the usability of developed theoretical framework in a real-life context; the small-sized company has been able to capture double digit growth path in recent years.
