Following example will clarify the difference between an event and activity: Completion of Machine Installation: An event. The normal convention is to go from left to right. In Arrow diagrams, each event node refers to the instant in which an activity is started or completed. Project Management, Scheduling, Network Construction and Development. The activities running in parallel face potentially having different completion times because they are dependent on the series of activities preceding. [In column y, item 1 represents Fig. Network diagrams are complemented by PERT and Gantt charts. Projects can be complex by nature and their planning can seem even more complex, especially when there are many activities and interrelations involved.

In particular, the study examines the four most significant social network structures, as found in the literature, and uncovers their specific network contents. If a project team wished to know the fastest time in which they could potentially complete the project, they must decide on the shortest possible time for each of the nodes. This may need to be done for a number of reasons. In other words, an event is an instantaneous point of time at which activity or activities start or finish. Prohibited Content 3. PROJECT MILESTONES Due Date deliverable Project Management Complete Structure and Plan the Project 4/16/98 Project Charter. If all the activities and events in the project are graphically represented showing their interdependencies, then a Network is obtained. In this method, first event in the network is numbered 1(or zero) and the second 2 and so on, in such a way that the event number at the tail of each activity arrow is always smaller them the event number at the head of that activity arrow.
