PERT ( Program Evaluation & Review Technique ) and Gantt charts are used in undertaking administration to represent the activities or tasks in a undertaking from start to end. They allow us to visualize the workflow and the undertaking plan. The main difference between PERT and Gantt charts is that they use different approaches to present the undertaking data.
The table below enlists the significant differences between PERT and Gantt Charts.
A Gantt chart is a bar chart used to represent the individual tasks associated with the project from start to end. PERT chart is a flow chart or network diagram which illustrates the project tasks along with their inter-dependencies.
The x-axis represents the time, and the y-axis represents the individual tasks. In the Gantt chart, the activities of the project are represented by a bar on an x-y axis. The position, the length represents the starting, ending, and duration of the activity or task.
Gantt Chart does not show the interconnection between the task while numerous interconnections are studied and represented in PERT networks. Gantt charts anticipate the time required to complete each task while PERT networks anticipate the time needed to complete the project.
