PROJECT MANAGEMENT
Internet Case Study: Shale Oil Company
1. The project network is shown below.
See file Ch07 Internet Case Shale Oil.XLS. The expected shutdown time is 45.75 days. There are 9
activities on the critical path: 1, 2, 3, 8, 16, 21, 27, 28, and 29. The variance of the critical path is 8.03,
