Three activities are candidates for crashing on a projectnetwork for a large computer installation (a ll are, of course, critical).Activity details are in the following table: a) What action would you take to reduce the critical path by I day?b) Assuming no other paths become critical, what action would you take to reduce the critical path one additional day?c) What is the total cost of the 2-day reduction?
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.

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.
The fo llowing is a table of activities associated with a project at Rafay lshfaq's software firm in Chicago, their durations, and what activities each must precede: a) Draw an AOA diagram of the project, including activity durations.b) Define the critical path, listing all critical activities in chronological order.c) What is the project completion time (in weeks)?d) What is the slack (in weeks) associated with any and all noncritical paths through the project?
