Note: The Crash duration represents the minimum duration where an activity is speeded up as much as possible.The crash cost represents the increased cost of the increased cost of the activity after it has been speeded up as much as possible. a) Draw a schedule showing the work package critical path and duration. b) Assume the work package has to be completed within 44weeks. Calculate the most cost effective way of completing the work package within this time, giving the cost increase associated with this crash sequence.
