PERT charts are network diagrams that use boxes to represent tasks and arrows to present dependencies between tasks. The boxes are laid out from left to right, but there is no fixed Y-axis with dates. The first box, or root, is centered vertically on the left side, and the subsequent tasks can be drawn anywhere along the Y-axis.
Arrows can point to the right, up or down, but never to the left. Task Dependencies A dependent task is one that cannot start until another task is partially or completely finished.
A Gantt chart can list subtasks grouped by task, which implies a sequence of dependencies. The sequence can be made explicit by drawing an arrow from one task to a dependent task.
PERT chart dependencies always require arrows. A task box can point to multiple dependent tasks. Furthermore, dependent tasks may have multiple incoming arrows when several tasks must finish before the dependent task can start.
Video of the Day Brought to you by Techwalla Brought to you by Techwalla Managing Schedules The Y-axis of a Gantt chart functions as a calendar, with equal-length segments representing units of time, such as days, weeks or months. This arrangement helps managers know when to start tasks and to quickly recognize when tasks are not on schedule.
The Pros and Cons of Using PERT and Gantt Charts
The spacing between task boxes on a PERT chart doesn't have to be proportional to the start and end dates, making the chart less convenient for managing deadlines. PERT, on the other hand, displays information as a network model. This means that a PERT chart presents an initial node from which tasks branch out.
This helps project managers visualize the sequence of tasks, as you cannot start on the next activity until the one preceding it is completed.

Work Breakdown Structure One of the key responsibilities of a project manager is to break down the workload into tasks to guarantee that the project will be finished by the deadline. Both PERT and Gantt charts will display the tasks to be completed, but the charts emphasize different pieces. In Gantt charts, the focus is on the percentage completion of each task, without demonstrating the link that two tasks may have to each other.
While PERT typically does not show the percentage completed, because it employs a network model, it is easy to see which tasks depend on each other. Simplification Gantt charts are ideal for straightforward projects with few interlinking tasks. Gantt charts present project tasks and time allocation as the only two pieces of data. While this is a limitation where there are interconnecting tasks that depend on each other, for more basic projects it is easier to interpret the data in a Gantt chart.
