CONVENTIONS FOLLOWED IN DRAWING NETWORK
The conventions followed in drawing a network are as follows:
- Draw the arrow directing from left to right, that is, time and progress of the project flows from left to right.
- As far as possible avoid drawing arrows that cross each other. Where ever crossing of arrows is unavoidable, bridging may be done.
- An activity is always bounded by two events, called the start event and the end event. No event should hang loosely on the network.
- Each node should be numbered without ambiguity. The numbers are assigned to events in such a way that the number assigned to the ending event of an activity is greater than the number assigned to the beginning event of that activity.
