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.

Summary
In case of dedicated software systems, having character of individual solutions, particular difficulties with reliable and objective cost estimation come about. Given that this is costs for ready-made software systems (socalled commercial off-the-shelf—COTS) being planned as with hardware spending, their estimation usually does not cause any serious difficulties since the client may base it on the market prices (often being negotiable). It often happens that the client spends those sums without supporting his decision on getting engaged in such investment by proper analysis of the costs, based on rational, sufficiently objective and reliable basis. For many years 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
