Gantt Chart
Named after Henry Gantt, display activities or events as a function of time (or cost). Each activity is shown as a horizontal bar with ends positioned at the starting and ending dates for the activity.
Advantages of Gantt Chart
- The charts are easy to understand
- Each bar represents a single activity
- It is simple to change the chart
- The chart can be constructed with minimal data
- Program task progress versus date is shown
Disadvantages of Gantt Chart
- They do not show interdependencies of activities
- The effects of an early or late start of an activity are not show
- There is no means to indicate the variation in expected time to complete an activity
- The details of an activity are not indicated
- There is little predictive value to this presentation of data
Advantages of PERT
- The planning required to identify the task information for the network and the critical path analysis can identify interrelationships between tasks and problem areas.
- The probability of achieving the project deadlines can be determined, and by development of alternative plans, the likelihood of meeting the completion date is improved.
- Changes in the project can be evaluated to determine their effects.
- A large amount of project data can be organized and presented in a diagram for use in decision making
- PERT can be used on unique, non-repetitive projects
Disadvantages of using PERT
- The complexity of PERT increases implementation problems.
* More data is required as network inputs
