 SO called template approach derived from (Robson 2000, p. 458). The interview topic scheme is derived from the general software market evolution model, and the software selection criteria are used as a supporting theory. The interviews in Europe were conducted by Dr Lauri Frank, Prof. Pasi Tyrväinen, and in some cases together with other members of the SmarTop project group. The interviews in Asia were con- ducted by Prof. Jari Veijalainen and Caleb Zhao who acted as an interpreter in all Asian interviews. These interviews were conducted in 2007-2008. The interview scheme remained the same in all interviews. 1.2 Interviewed Operators The CSP companies that were interviewed cover an area depicted in dark gray in the map (see Fig. 1). The geographical area of operations of these telecom Insights from Operator Interviews Fig. 1 The area of operations of the interviewed operators shown in dark gray companies covers Northern Europe, Eurasia, and parts of Middle and South Europe (North American market is rather well covered with the quantitative data analyzed in the subsequent sections of this chapter, and hence no interviews with the operators in that market were conducted). The operators interviewed Europe are classified as "Regional" if they operate only within a regional area in one country, as "National" if they have activities in one or two countries, and as "International" if they operate in several countries. Since the rapid economic development in Asia is maybe one of the greatest factors in the current CSP and related software business, a second wave of inter- views was conducted with Asian operators in mainland China and in Taiwan. The operators interviewed in Asia fall into two categories: National or Regional, in general larger in size than those in Europe. Due to demographics, Asian operators typically serve a larger customer base than do European operators. In the following tables are the details of the companies where the interviews were conducted.
