IT314 - Software Engineering 3 Gantt Chart (1/3) The Gantt chart is a graphic display of the duration of a set of activities. The activities are listed along the left side of the chart and a time line is given at the top or bottom of the chart. The duration of an activity is shown with a horizontal bar that extends over the applicable period of the time line, starting from the starting date of the activity and ending at the ending date for that activity.

IT314 - Software Engineering 4 Gantt Chart (2/3) The start and end date of each activity become milestones for the project. Progress can be represented easily in a Gantt chart, by ticking off each milestone when completed. Alternatively, for each activity another bar can be drawn specifying when the activity actually started and ended. The main drawback of the earlier versions of the Gantt chart was that it did not depict dependency relationships of different activities.

IT314 - Software Engineering 6 PERT Chart (1/6) PERT stands for Program Evaluation Review Technique , a methodology developed by the U.S. Navy in the 1950s to manage the Polaris submarine missile program. A PERT chart is a project management tool used to schedule, organize, and coordinate tasks within a project. For large projects, the dependencies among activities are important to determine which are the critical activities, whose completion should not be delayed.

IT314 - Software Engineering 7 PERT Chart (2/6) NOTE: A similar methodology, the Critical Path Method (CPM), which was developed for project management in the private sector at about the same time, has become synonymous with PERT, so that the technique is known by any variation on the names: PERT, CPM or PERT/CPM A PERT chart is a graph-based chart and can be used to determine the activities that form the “critical path”.

IT314 - Software Engineering 8 PERT Chart (3/6) A PERT chart presents a graphic illustration of a project as a network diagram consisting of numbered nodes (either circles or rectangles) representing events, or milestones in the project linked by labeled vectors (directional lines) representing tasks in the project. The direction of the arrows on the lines indicates the sequence of tasks. Numbers on the opposite sides of the vectors indicate the time allotted for the task.
