- What is PERT
- PERT chart is a network diagram for project scheduling and timeline representation
- Uses optimistic, most likely and pessimistic time estimates for each task
- Developed by U.S. Navy in 1957 for Polaris nuclear submarine project
- How to Use
- Used during project planning phase to determine critical path and task dependencies
- Made up of nodes (milestones) and directional arrows showing task sequence
- Requires breaking down project scope, creating diagram, estimating durations and calculating critical path
- Advantages
- Helps simplify complex projects and visualize dependencies
- Facilitates communication between multiple departments
- Allows exploring what-if scenarios and identifying project bottlenecks
- Limitations
- Requires experience and continuous updates
- Labor intensive and needs accurate data input
- Not suitable for all project sizes
- Comparison with Gantt
- PERT charts better for larger, complex projects
- Gantt charts used for smaller projects and project execution
- ProjectManager offers dynamic Gantt chart with task dependencies and real-time updates
