A Life Cycle Cost Data Base for Automated Data Systems

Abstract

When it is necessary to project the cost of a new automated data system (ADS), are your analysts using a base of data derived from the development of your systems? Or are your estimates being made, based upon data from a source outside your organization? Several data bases are made up of data from a wide range of sources. Using these creates many questions, such as: are the data really pertinent, what bias is introduced by using somebody else's data base, and could the impact of biased data be identified? We often hear that there is no widely accessible base of data that is usable to estimate software costs. The literature is replete with statements lamenting the lack of ADS cost data, but most of the recently developed cost models require the input of historical cost information, or estimates of the same, in order to obtain usable results. At AFLC, we took a straight forward approach to solving this problem.
