PERT Chart
PERT chart is a technique for scheduling a project based on individual tasks or activities whereas Gantt Chart is a bar chart that represents the tasks and activities of the project schedule.Source: Satzinger, J., Jackson, R., Burd, S.

A PERT (Program Evaluation and Review Technique) chart is a graphic representation of a project schedule, showing the sequence of tasks, which tasks can be performed simultaneously, and the critical path of tasks that must be completed on time in order for the project to meet its completion deadline. A Gantt chart is another representation of a project schedule, but specifically uses a bar chart.

Since PERT stands for Program Evaluation and Review Technique, then it would be as if you're making a sentence with the word technique by itself, as a common noun. The rest of the acronym is just what describes that word. So, an example would be: We should use the PERT to manage the project better. You could also use it as a proper noun, which is a name: PERT helped us to improve the analysis and organization of this project. Or as an adjective: For the events and activities, we used a PERT chart.
