1.     Both separate planning and scheduling. In network-based project, network planning precedes scheduling of work and budgeting of resources.

2.     Both enable systematic and logical development of time programme of complex projects with resource constraints. In these programmes, the scope of work and interconnection between activities get clearly defined.

3.     Both depict interdependence diagrammatically. This makes for easy comprehension of the tasks involved, anticipation of potential problem areas and judging the implication of changes.

4.     Both help in establishing a relationship between time and cost, thus enabling optimization of resources.

5.     Both are independent of time axis and, therefore, do not become outdated with the passage of time.

6.     Both aid in establishing key events, scheduling of work, budgeting of resources and measuring of risks on a scientific basis.

7.     Both provide basis for monitoring progress and analyzing effect of deviations.

8.     Both help in exercising management by exception, by focusing thought of the management on critical activities.

9.     Both provide the common language for communication among all those connected with management of projects thus reducing communication gaps, coordination effort and contractual disputes.
