In the last few years many aspects of computers and computer science have progressed from black art mystery to a precise science. One of the black arts that still remains is the ability to correctly estimate the cost of upgrading or expanding data processing operations, particularly those resulting in the changing of vendors. The federal government has been particularly plagued by gross underestimation of large-scale conversion costs in the past. Management responsible for making sound, economical decisions often lacks the experience in cost estimation needed to even include all the factors necessary for consideration when procuring new equipment. This thesis provides a guide to the manageranalyst who must develop a cost estimate to be used to select among competing vendors. Current cost estimation techniques are reviewed within the framework of government purchasing regulations and guidelines affecting computer procurement. Separate sections discuss intangible factors and their importance to the selection process. This background sets the proper perspective for the thesis case study, which provides the basis for a post-implementation development of a list of intangible factors. Author
