Years ago I met a CFO who had just finished grilling his tech guy for over an hour getting the tech guy to come up with a worst case scenario for the project they were about to begin. In that hour the tech guy nearly tripled his time and cost estimates. After he left the CFO doubled the time and cost estimate for the budget. In the end the CFO was nearly bang on.
I would say this is a good CFO. The CFO understood that he had a choice: get it done quickly, or get it done right the first time; and he chose the latter.
