Probability the project will be completed in 70 weeks. 4. Suppose you are hired as a consultant to decide whether it makes economic sense to crash the project. You are given the normal cost, crash cost, normal time, and crash time information. The overhead costs incurred by the project every week are $10,000. a. Determine whether you should crash the project. b. Complete the Sheet "crash costs" in the Excel file HW1. c. If yes, how many days would you advise the project should be crashed? Why?
