[Code of Federal Regulations] [Title 48, Volume 1] [Revised as of October 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 48CFR37.602-4] [Page 742] TITLE 48--FEDERAL ACQUISITION REGULATIONS SYSTEM CHAPTER 1--FEDERAL ACQUISITION REGULATION PART 37_SERVICE CONTRACTING--Table of Contents Subpart 37.6_Performance-Based Contracting Sec. 37.602-4 Contract type. Contract types most likely to motivate contractors to perform at optimal levels shall be chosen (see subpart 16.1 and, for research and development contracts, see 35.006). To the maximum extent practicable, performance incentives, either positive or negative or both, shall be incorporated into the contract to encourage contractors to increase efficiency and maximize performance (see subpart 16.4). These incentives shall correspond to the specific performance standards in the quality assurance surveillance plan and shall be capable of being measured objectively. Fixed-price contracts are generally appropriate for services that can be defined objectively and for which the risk of performance is manageable (see subpart 16.1).
