How do i fully crash a critical path when given the following question. a) Fully crash the critical path taking the work package back to the shortest possible duration. You should thwith the activity with the lowest cost per unit crash time and progress to the activity with the highest cosp per unit crash time. Show the crash sequence of cost against time using suitable form of graphical representation. b) Summarize the main sources of duration estimating data used by organizations when assembling project schedules.
