ABSTRACT
Project time and cost management in the waterfall model involves two principal stages: the estimation in the definition and planning stage of the project and the control in the realisation stage of the project. There are several estimation methods for IT projects, among which parametric methods are distinguished, especially those based on the COCOMO models. For the realisation stage of IT projects, the earned value analysis (EVA) in its basic form is recommended for use. The thesis of this paper is that the information scope used in each of those stages is unevenly distributed: a large amount of information is used in the first stage and a rather limited one in the second. A more even distribution of information would increase the efficiency of project cost and time management. The respective proposal is described, and its potential usefulness is justified theoretically and through a real-world case study – an IT project that has failed.
