PERT diagrams show growth, production and productivity.

What is the advantage of the PERT diagram over the GANTT chart?

PERT diagrams (network diagrams) shows the relationship between activities and time frames graphically however, even start and finish date are included dough it differ from GANTT.

Does this means depending on what has to be constructed or has to be achieved, the project manger decides which project management tool has to be used? Are there a possibilities of managing more than one of these tools to carry out the project?

PERT diagram is relationship betweem activities and time frames

project are very critical so you must know how long it take in terms of time frames and how to arrive there

Key elements in developing a PERT diagram: 1.Activities - list of activities in the project and their dependencies 2.Nodes/Events - indicating the beginning or end of an activity 3.Network lines show the interdependence of events 4.Indication of the critical path - the sequence of dependent events that have the sum of longest duration 5.Indication of slack time - events not on the critical path usually have slack time, extra time for that event that does not effect the timing of other events thus not effecting the project time. That means that can fall behind schedule and there is no impact on the project completion date. What will happen when the Key elements for developing a PERT diagram is not found what will be the indication of the beginning and the end of the project?

PERT makes planning single large project’s activities easy. It shows clear display of project activities allowing the project manager to analyse “what if” situations.

Information Technology -> PERT diagrams (network diagrams) PERT Diagrams (network diagrams) PERT diagrams or critical path networks use a graphical form to show relationships between activities and time frames. Part of a PERT diagram. Notice that for each event start and finish dates are included. They differ from GANTT charts in that they are better at identifying the relationship between tasks rather than the progress of tasks over time. Key elements in developing a PERT diagram: Activities - list of activities in the project and their dependencies Nodes/Events - indicating the beginning or end of an activity Network lines show the interdependence of events Indication of the critical path - the sequence of dependent events that have the sum of longest duration Indication of slack time - events not on the critical path usually have slack time, extra time for that event that does not effect the timing of other events thus not effecting the project time.

If you wish to have a play with creating your own GANTT charts and PERT diagrams, there a number of trial versions available on the Internet.

What difference can we find out between GANTT and PERT?
