Current problems of IT project development management include reducing the irrational use of expensive specialist time, as well as minimizing reputational and other losses due to unexpected system service failures.The aim of the research, which is devoted to the article, is the quantitative accounting in the cost optimization model of the main processes of IT project development.The results of computational experiments on data from real IT projects made it possible to clearly see that, from an economic point of view, the proposed management decisions lead to a reduction in unjustified costs and a minimization of possible losses. As a result, using the simulator, you can more consciously debug the project implementation process and increase the predictability of the team's work and the state of the project, as well as optimize the use of resources.As a conclusion of the conducted research, the model of IT project implementation proposed in the article and the project execution simulator program developed on its basis can be used to calculate the effect of multidirectional optimizations with different cadences.The source codes of the simulator program are open and available for downloading, use and adaptation.
