If the due date to finish the project is 10 weeks, crash the project to meet the due date.

Find the duration of each activity, the critical path and the cost of crashing the activities after crashing the project to due date. FINISHExplanation / Answer
Start the project by getting the values from start as Early start(ES) to Early Finish(EF).
Now start discussion about Late Start(LS) and Late Finish(LF). As shown in Example, Our Project completed at 12 weeks. Thus, Late Finish uses Backward Pass to reach at each node.
