1.4 Did you notice any difference in the float/slack of the critical activities you identified in activity 1.2? Identify all the path of the project on the network diagram. Write down the critical path activities and calculate the duration of the critical path. Also identify the shortest possible path on the network and calculate its duration (10) 1.5 Program Evaluation and Review Techniques (PERT) is a form of a network analysis developed to take account of the uncertainty surrounding estimates of task duration. To use PERT, you will need to calculate a weighted average for the duration estimate for each project activity and this will give the expected duration (t) for each single project. Using the activities estimated duration depicted on Table 1 and Optimistic and Pessimistic times on Table 2 below calculate the expected duration (PERT weight average) for each of the 4 project activities on Table 2 Optimistic Pessimistic Expected (te) (b) 3 6 A B 1 3 C 3 D D 4 5 Table 2 1.2 Table 1 depicts the project activities for a small IT project graduation recording system. Draw Activity-on-Arrow diagram to illustrate the interaction of these activities representing the project. For example, see Figure 6.2 of your textbook. Make sure you include the forward and backward pass on your diagram. Indicate the critical path of the project. Conduct a research on how you would calculate the float/slack of the critical path activities. Then calculate the float/slack of the critical path activities. 1.3 To enable the calculation of free and total slack, perform a forward and backward pass on the network diagram you created in question 1.2. Convert the AOA diagram you created to follow the format of Figure 6.9 of your textbook BUT NOTE THAT ACTIVITY I SHOULD NOW ONLY DEPEND ON ACTIVITY E. Include the calculations values of the forward pass (earliest dates) and backward pass (latest dates) on the nodes.
