ABSTRACT Dedicated software systems hold a character of individual solutions that entail particular problems with regard to their cost estimation. Thus for many years now objective and reliable approaches to the cost estimation of such systems have been sought out so that they could provide the possibility to make rational investment decisions concerning those systems. The purpose of this paper is to bring in the approach to cost estimation of dedicated software systems that has been recently growing in global popularity, using it as a background for presenting conclusions resulting from practical verification of author’s own model of dedicated software system cost estimation based on that approach.
