Gantt charts and network diagrams are commonly used tools in project management to schedule tasks within a project. By varying individual task predecessors and task durations, this Demonstration allows for a simple exploration of basic project management concepts, such as determining project duration, the critical path, and total slack. Changes can be observed in the project network, Gantt chart, and a summary table. On the Gantt chart, task durations are indicated in black and slack time in gray.
