You have been assigned to be a project manager for a supplier to ABB Power Generation Systems. ABB is designing and fabricating turbines for a hydroelectric plant to be installed in northwestern India. Your component is to be air-shipped to Jammu, where it will then be transported to the site via surface transportation. The data are given below. (a) Calculate the expected activity completion times for each activity using data in the table below, using this formula: expected activity completion time = (optimistic duration +4 most likely duration + pessimistic duration) /6. (b) Using the calculated expected activity completion time from (a) as the task time, develop a CPM diagram for the project, identifying the early start, early finish, late start, and late finish times for each activity; also identify the critical path of the entire project. Use the AOA methodology discussed in class
