The project network is: When all activities are completed in normal time, what is the critical path? Enter the letters of the activities on the path in capitals (e.g. ABCDEFG). When all activities are completed in normal time, what is the project completion time? To reduce project completion time by 1 week at minimum cost, which activity should be crashed? Enter the letter for the activity. What is the incremental cost to reduce project completion time by 1 week at minimum cost?
