Abstract: A Network Diagram Application arranges multiple activities relative to a timeline to improve user visualization, facilitate editing, and provide a user-friendly interface for linking activities. The Network Diagram Application enables creation of store points which reflect the state of activities at that point in time. Store points may be accessed to compare how activities have changed over time. A Critical Path Method Checker reviews the activities and their relationships to determine if all information is within requisite parameters to avoid problems during the project.
