• A Gantt chart is a special case of horizontal bar charts used to portray project timelines, project tasks/activity durations, and overlap among the tasks/activities. By showing start and end dates/times of tasks/activities and the overlapping relationships, Gantt charts provide an invaluable aid for management and control of projects. For instance, Gantt charts are often used to show project timelines, task overlaps, relative task completions (a partial bar illustrating the completion percentage inside a bar that shows the actual task duration), resources assigned to each task, milestones, and deliverables.
• The PERT chart (also called a network diagram) is developed primarily to simplify the planning and scheduling of large and complex projects. A PERT chart shows precedence relationships among project activities/tasks. It is composed of nodes (represented as circles or rectangles) and edges (represented with directed arrows). Based on the selected PERT chart convention, either nodes or the edges can be used to represent the project activities/tasks (activity-on-node versus activity-on-arrow representation schema).
