Exercise 9

You are in charge of developing the software for a product that uses a set of newly developed algorithms to compute the most cost-effective routes for a large trucking company. Using intermediate COCOMO, you determine that the cost of the product will be $470,000. However, as a check, you ask a member of your team to estimate the effort using function points. She reports that the function point metric predicts a cost of $985,000, more than twice as large as your COCOMO prediction. What do you do now?
