Question 1 of 8
You are selecting a vendor for a complex software development engagement where requirements are not fully defined. Which contract type best protects the buyer while still incentivizing the vendor?
- A.Fixed-price lump sum contract
- B.Time-and-materials contract with a not-to-exceed ceiling
- C.Cost-plus-incentive-fee contract
- D.Cost-plus-fixed-fee contract
Show answer and explanation
Correct answer: C
A cost-plus-incentive-fee (CPIF) contract reimburses allowable costs and adds a fee that increases when performance targets are met — aligning vendor incentives with buyer outcomes. Fixed-price is risky when requirements are unclear, as vendors will price in uncertainty or fight scope changes. T&M with ceiling protects cost but provides no performance incentive. CPFF reimburses costs plus a fixed fee regardless of performance.
