Especially in developing nations, defining the benefits from unit investments in telecommunica- tions is a challenge at national, regional and or- ganizational levels. This paper addresses the prob- lem in terms of measurable criteria that can be used to examine ex ante the feasibility of investments in networking services. The methodology involves development of realistic dependent and independent variables based on varying assumptions about the depth and quality of services being considered. Specific data from implementations now going on developing nations in four continents is included.
