Given the activities whose sequence is describedby the following table, draw the appropriate activity-on-arrow (AOA) network diagram.a) Which activities are on the critical path?b) What is the length of the critical path?
A plumber has decided to use the techniques of project management in order to plan a job. He knew all the different activities of the job, their precedence and their average durations. They are shown on the table below.

B and C
Required:
1. Draw a network diagram representing the sequence of activities and the dependence between them.
2. Determine how long it will take to complete the job by conducting the forward pass
3. By conducting the backward pass, identify the critical path and the non-critical path(s).
Note:
The work for this task should be produced using Word drawing facilities. The forward and backward passes should be clearly shown on the diagram. The calculations should be shown next to the network diagram.
