Traditionally software development is described by different process oriented models, so-called process models or v-models. Project management of the software development process requires a modified view which is achievable by aggregation of elementary building blocks of the selected v-model. We propose an approach which is independent of v-models and forms the basis of the development of a project management system which can be applied in real time. The usage of simulations during the entire project optimizes the assignment of resources and reduces the requirement of external decisions.
