Comparison between the Gantt chart and PERT

PERT (program evaluation and review technique) is one of the statistical tool that is used in project management to analyze and represent the tasks involved in the completion of a given project while a Gantt chart is a horizontal tabular bar chart which shows the project schedule that is it shows the start and finish dates of the terminal elements of the project and summary elements of a project.

The Gantt chart may be used in status reporting to show and present how much of the plan has been completed by displaying and showing the progress of an activity.

The information received from a Gantt chart is more helpful because, the information in a Gantt chart is graphical hence easily understood than in the PERT which just shows arrows and nodes.

It is easier to draw and present the information in a Gantt chart and be used in the analysis of the project because it shows both the estimated and actual time the project takes compared to the PERT which only shows the earliest start time and Latest end time of an activity.

Gantt charts are simple and easy to read while PERT may not be easily understood.

The PERT provides useful information since it can show the critical path and the critical activities hence helpful in planning the resources of the project compared to the Gantt chart which only shows the activity duration and the predecessors.

When using the PERT, it shows the information on the activities and shows the slack activities and when to start and end in case of a dummy activity.

Application of Gantt charts and PERTS

Gantt charts are used when planning for small projects while PERT can be used when planning for large projects. This is because many interlinking activities are difficult to represent in the Gantt chart and also the duration may be large to be represented.

Importance of Critical path

i. It will display all the activities of the project and it will help to plan on how to do the activities such that the slack activities can be started either earlier or late.

ii. It can help to reschedule the resources of noncritical activities to the critical activities hence accelerating the project activities.

iii. The critical path can be used to calculate the standard deviation of the project and the covariance to know how correlated the activities in the project are.

iv. The critical path is what determines the duration of the project since it shows the activities that shows takes the longest duration between the start and the end of the project.
