The predecessor diagram and data listed below has estimates of the normal time (NT) in weeks listed for the activities: a-1. Determine the critical path. A.C.F.G A-B-D-G A.C-E-G A.D.E. A A-C.E-G A-B-E-G a-2. Determine the early completion time in weeks for this project. Early completion time weeks For the data shown, reduce the project completion time by three weeks. Assume a linear cost per week shortened. b-1. Which activities in order of reduction would be shortened? A-G-D D.G-A G-D-A D-B-C b-2. Find the resulting cost to crash. Resulting cost to crash
