PERT Chart vs Gantt Chart are two commonly used tools in project management that offer different perspectives and serve different purposes. Here is an in-depth comparison highlighting the key differences between Gantt Chart vs PERT Chart:

1. Basis and Origin

Gantt Chart: The Gantt Chart is based on Project Management Theory and was developed by Henry Gantt in 1910. It provides a visual representation of project tasks, durations, and dependencies.

PERT Chart: PERT (Program Evaluation and Review Technique) Chart uses the critical path method and was initially proposed by the US Navy in 1957. It gained popularity in project management practices about 30 years later.

2. Approach

Gantt Chart: The Gantt Chart focuses on displaying the project schedule in a linear timeline format. It emphasizes the order of tasks, their durations, and the responsible individuals or teams. It helps in visualizing project progress and resource allocation.

PERT Chart: The PERT Chart primarily uses the critical path method to identify the critical path and determine the minimum time required to complete a project. It analyzes task dependencies and calculates durations based on these relationships.

3. Task Dependency and Critical Path

Gantt Chart: While Gantt Charts can show task dependencies, they do not explicitly highlight the critical path. Task dependencies are usually represented through task interconnections, but the critical path analysis is not a central focus.

PERT Chart: PERT Charts excel in identifying and visualizing the critical path of a project. By analyzing task dependencies, PERT Charts determine the longest path through a project, which helps in understanding the most critical tasks and potential bottlenecks.

4. Planning and Estimation

Gantt Chart: Gantt Charts are widely used for planning projects, scheduling tasks, and managing project resources. They provide a clear overview of the project timeline, allowing project managers to allocate resources and monitor progress.

PERT Chart: PERT Charts are particularly suitable for projects with multiple tasks, milestones, or deliverables. They facilitate task planning by identifying the sequence of activities and estimating their durations using optimistic, most likely, and pessimistic estimates. PERT Charts assist in determining the expected completion date and assessing project feasibility.

5. Project Execution Monitoring

Gantt Chart: Gantt Charts primarily focus on displaying the project schedule and timeline. They provide a static view of the project, allowing stakeholders to understand the planned schedule and milestones. However, Gantt Charts do not provide detailed information on day-to-day execution or progress tracking.

PERT Chart: PERT Charts are not specifically designed for day-to-day progress tracking. They are more useful for analyzing critical tasks and identifying potential delays. PERT Charts provide insights into the overall project timeline, but they do not offer real-time monitoring capabilities.

In summary, Gantt Charts are effective for visualizing project schedules, managing resources, and tracking progress, while PERT Charts are valuable for identifying critical paths, estimating project durations, and analyzing task dependencies.
