The project duration, ii. The earliest start and finish time of each activity, i. The latest start and finish time of each activity, iv. The slack of each activity, v. The critical path(s). c. Which activity or activities should be crashed and in which sequence to reduce the project duration by 2 weeks? d. What is the resulting total project cost? e. What is (are) the critical path(s) of the project after crashing?
