Network Diagrams

On the basis of events and activities and the order or sequence in which they will happen within the project the Project Manager can develop what is called a network diagram. The Project Manager also has to determine which activity takes precedence over another, i.e. which must happen before another can take place. These are, except in the simplest of cases, very difficult to construct by hand, unless the person is very experienced, and available software is of a great advantage.

Taking the list of tasks given in the Gantt Chart for Product X the order of precedence can be drawn up.

Task

Precedence

A.

Process developed

None

B.

Hazards evaluated

A

C.

Plant modifications designed

A, B

D.

Equipment delivered

C

E.

Plant modified

C, D

F.

Chemicals delivered.

A, B, C

G.

Start up team trained

E

H.

Trial Manufacture completed

E, F, and G

The network diagram derived from these activities is shown in Figure D18.

The complexity of the diagram rapidly increases when further tasks are added, particularly those that are carried out in parallel to the main activities. They can then be used for determining the critical path in a complex project.
