Demonstrate the crashing steps needed to minimize the cost of crashing down to various project lengths. Consider project lengths of 18, 17, 16, 15, 14, and 13 weeks. For each possible step down in project length, specify which activity would be crashed to achieve that length, compute the resultant length of each path in the project, and compute the crashing costs as shown in the table below.
