| Abstract: | The new network economy is characterized by the continuous introduction of innovative both telecommunication services and business application services, which run on powerful fixed and mobile network infrastructures. The exploitation and the profitability of these network infrastructures depend heavily on the commercial success of the services running on them. One of the most critical preconditions for the success of these services is to be based on sound business models. For this reason, the concept of ‘business model’ has become quite popular among business consultants, managers and entrepreneurs, especially today, in the dawn of the new networked economy. However, despite the extensive use, and sometimes misuse, of the business model concept, only limited scientific research has been conducted in this area. Moreover, there is still some ambiguity concerning the exact meaning of this concept, which results in a diversity of definitions and a confusion in terminology. In the present paper, initially we present a literature review on the definitions, the components and the theoretical foundations of business model. Then we focus on emerging business models for telecommunication and business application services and their success factors. Finally, we review the limited research that has been conducted so far concerning methodologies for designing new business models, we identify its shortcomings and we propose a new framework for ‘digital’ business model design. |
