This request does not indicate that the Government has selected an incentive contract type. Responses will help assess competition, price reasonableness, administrative burden, risk allocation, and whether an incentive structure for Option 4 would improve cost, schedule, and delivery outcomes compared to firm-fixed-price pricing. The market research should determine whether Option 4 incentive pricing would reduce contingency and improve delivery outcomes, or whether firm-fixed-price for Option 4 remains simpler and more competitive.
