1. The network diagram

‘A network diagram is originally a flow chart that includes all of the project events and relation of each activity.’  (Rick A. Morris)

The network diagram (Appendix 1.0) has been drawn out accordingly to the table for Mangeist Ltd for present activities and timetable it takes to customer forklift trucks for its customers.

The backward pass is start from right to left which uses the activity latest start time (LS), latest finish time (LF) and total float (TF). At the same time, duration is provided in the activity data.

3. The project duration and the critical path.

This project of duration uses 88 days for completion, which is using LST to add up together with the duration of the activity. Critical paths generally have two kinds, which are zero and negative total float. So the project critical paths are activity A→D→G→H→I→K→L→M→N→P→Q. The zero float showed in the activities are indicate as the critical path or critical activities.
