ABSTRACT
The purpose of the test cases, called “the cases” is to test the heuristically found qualitative relationships between the input parameter “regulatory environment” in the country and the country’s telecommunications services offering, and the output parameter cost-effective management of the network. The people interviewed were network managers and managers of the information technology departments. Experience has shown that several interviews are necessary to collect adequate information, and often the information about performance of the network must be calculated from system reports. Cost of ownership, size of the network, and performance of the network are the measurements that must be assembled for the cases. The size of the network is measured by taking the totals of the capacity of the links for each of the countries in the case. The Calvin Klein Cosmetics Company international network primarily performs data services. The connections between the US headquarters and the affiliate offices in Europe carry data exclusively.
