Contemporary project management needs high-level quantitative representations of projects for their successful planning and execution. Such representation is possible on the basis of balance equations for the total effort of the project. On the basis of this balance equations can be obtained so-called state equation of projects. This paper presents the derivation of this new equation that incorporates project size, project reuse, project duration, project total effort, team size, team productivity and project difficulty. In contrast to existing bottom-up methods of project presentation in the form of statistical relationships between project parameters this new top-down methodology is not a data driven and therefore is more accurate and stable.
