The question was:
What technique is used during the preparation of the business case to measure the excess or shortfall of the project cash flow?
The answer is:
Net Present Value
This question was a bit tricky as the BABOK does not define these techniques. In section 2.5.9 you will find a list of different techniques. Make sure you know where and when to use these techniques. A good definition of NPV is found on wikipedia.
