Which item is least likely to drive differences between contractor and government cost estimates?

• A. Long lead items
• B. Labor rate assumptions
• C. Items with small impact on overall program cost
• D. Schedule risks

Answer: (C)

Differences in contractor and government cost estimates mainly come from the big cost drivers that can move the total, such as procurement timing, labor costs, and schedule risk. Long lead items affect when and how much you pay, because delays or price changes for scarce items can push up the overall cost estimate. Labor rate assumptions matter because direct labor often makes up a large portion of the budget, and differences in wage, benefits, overtime, or escalation can create sizable gaps. Schedule risks influence how much contingency and risk allowance is built into the estimate, changing the projected total based on perceived uncertainty. Items with small impact on the overall program cost don’t significantly affect the total, so disagreements about them don’t usually drive meaningful differences between estimates.
