A contractor wants to know whether his team can complete the following small project within 25 days. a) Use a CPM analysis to answer this question. The dependencies and durations are given in Figure 1. [45 marks] b) The contractor is also curious to know whether the project could be finished within 25 days with a probability of 50 percent or higher. Use PERT analysis to answer this question. Durations are given in Table 1. (45 marks] c) What are the limitations of using PERT for this project? [10 marks] E B 5 H 8 A 6 4 F 3 I 6 K D 6 G 2 6 Figure 1.
