You assume that this trend will continue and you estimate that you are going to have to make up 5 week in order to stay on track and reach your target delivery date. As such,  you decide to crash your project. Below are the tasks that you consider crashing. Which one  would you crash in order to gain 5 weeks?

In reality, I would look deeper at what the task is specifically set to accomplish and what the associated risks of crashing are.  If this is all I have to go on, A saves the three weeks and "appears" to be lower risk due to costs (lowest total cost per week before and after crashing).  What's more, its not on the critical path where I might not want to add more risk.
