a) Perform critical path analysis by hand. What is the minimum project duration?
b) Now use MS Project software and perform critical path analysis. Start date for this project is March 15, 2014. We use a standard calendar. When should we complete this project? Compare results from question (a) and question (b).
c) Use MS Project software and perform critical path analysis when we are introducing a lag of 3 days at the start of D and a lag of 4 days at the start of H. We are introducing a lead of 3 days at the start of F. We use standard calendar. Start date for this project is March 15, 2013. Mark I as milestone activity. When should we complete this project? The deadline is set as May 1, 2014. Can we finish this project by the deadline date? Support your answers with printouts from MS-Project software.
d) What are the WBS codes for A and G. Hint: Go to task information and find WBS codes.
