Network diagram

The Network diagram, one of the seven management tools in project management, is a technique for representing processes or their individual steps, as well as for analyzing, controlling and scheduling projects. It makes possible buffers visible and identifies the critical path, which allows no delays. The Network diagram consists of all project-relevant activities, which are grouped and ordered in the sequence of their execution. For each activity, the earliest possible start and end times are calculated based on its duration. Subsequently, backward from the last activity, the latest possible start and end times are derived.
