Critical Path Method steps for completing a project planning

• It is necessary to break up the project work into various activities.

• It is necessary to label all these activities.

• All the activities should be arranged in a logical sequences.

• Arrow diagrams need to be prepared.

• All the nodes (events) and activities have to be serialized and numbered.

• The time required for each activity has to be calculated.

• It is necessary to work the activity times on the arrows diagrams.

• It is also necessary to calculate early and late start and finish timings.

• It is necessary to tabulate the timmings and make the earliest start time (E.S.T.) and the latest finish time (L.F.T.) on the arrow diagram.

• The float of each activity needs to be calculated.

• It is necessary to identify the critical activities and critical path on the arrow diagram should be marked.

• It is possible that one can calculate the total project time duration.

• It is possible to reduce the total project time duration, by crashing the critical activities of the network.

• It is necessary to optimize the cost.

• It is necessary to bring the network up to date.
