FAR 37.503—Agency-head responsibilities.
Plain-English Summary
FAR 37.503 assigns agency-head-level oversight responsibilities for service contracting. It covers four core topics: defining service requirements and performance standards, awarding and administering service contracts to deliver supplies and services on time and within budget, putting procedures in place to prevent contractors from performing inherently governmental functions, and developing implementation strategies plus staff training for the policies in FAR 37.102. In practice, this section is about governance and control at the top of the agency: it requires leadership to make sure service acquisitions are planned well, managed consistently, and aligned with legal limits on contractor involvement. The purpose is to reduce vague statements of work, cost and schedule problems, improper outsourcing of government functions, and inconsistent application of service-contracting policy. For contractors, it signals that agencies should be better prepared and more disciplined in how they define, buy, and manage services; for contracting officers and program officials, it means the agency must have the systems, training, and internal procedures needed to support compliant service acquisitions.
Key Rules
Define requirements clearly
The agency head or designee should ensure service requirements are clearly defined and that appropriate performance standards are developed. This helps potential offerors understand what the agency needs and supports contract performance that actually meets the agency’s mission needs.
Use measurable performance standards
Performance standards must be developed so contract terms and conditions can be evaluated against objective expectations. The point is to avoid vague service descriptions and to make it possible to determine whether the contractor is meeting the agency’s requirements.
Deliver on time and within budget
Service contracts must be awarded and administered in a way that provides the customer with supplies and services within budget and in a timely manner. This is a management expectation that reaches beyond award to contract administration and delivery outcomes.
Protect inherently governmental work
Before contracting for services, the agency must have specific procedures to ensure inherently governmental functions are performed by Government personnel. Agencies must screen proposed service work carefully so they do not outsource decisions or activities that must remain with federal employees.
Implement service-contracting policy
The agency head must ensure strategies are developed and staff training is initiated to support effective implementation of the policies in FAR 37.102. This means the agency needs both a plan and trained personnel to apply the service-contracting rules consistently.
Responsibilities
Agency Head or Designee
Ensure service requirements are clearly defined, performance standards are developed, service contracts are managed for timely and within-budget delivery, procedures exist to prevent contractor performance of inherently governmental functions, and strategies plus training are in place to implement FAR 37.102.
Contracting Officers
Apply the agency’s service-contracting procedures, help ensure requirements are well written and measurable, and administer contracts so the customer receives the needed services on schedule and within available funds.
Program and Requirement Owners
Define the agency’s service needs clearly, support development of performance standards, and identify any work that may involve inherently governmental functions before the acquisition is planned or awarded.
Agency Acquisition and Training Officials
Develop implementation strategies, create or deliver training, and support consistent application of service-contracting policy across the agency.
Contractors
Perform only the work assigned under the contract, meet the stated performance standards, and avoid any involvement in inherently governmental functions reserved to Government personnel.
Practical Implications
Agencies should expect stronger upfront planning for service acquisitions, especially better-written statements of work and clearer performance metrics. Poorly defined requirements are a common source of disputes, cost growth, and unsatisfactory performance.
Contracting officers and program offices need to check whether the work includes any inherently governmental elements before solicitation and award. A common pitfall is allowing contractor support to drift into decision-making, approval, or oversight roles that must remain with federal employees.
Budget and schedule discipline matter throughout contract administration, not just at award. If the agency does not actively manage service contracts, it can end up with late delivery, scope creep, or spending that exceeds available funds.
Training is not optional in practice: agencies need personnel who understand service-contracting policy, performance-based acquisition, and the limits on contractor involvement. Without training, even well-written policies are often applied inconsistently.
For contractors, this section usually means clearer expectations and fewer ambiguous tasks when the agency does its job well. But it also means contractors should be alert to scope changes and to any request that could implicate inherently governmental work, and should seek clarification before proceeding.
Official Regulatory Text
The agency head or designee should ensure that- (a) Requirements for services are clearly defined and appropriate performance standards are developed so that the agency’s requirements can be understood by potential offerors and that performance in accordance with contract terms and conditions will meet the agency’s requirements; (b) Service contracts are awarded and administered in a manner that will provide the customer its supplies and services within budget and in a timely manner; (c) Specific procedures are in place before contracting for services to ensure that inherently governmental functions are performed by Government personnel; and (d) Strategies are developed and necessary staff training is initiated to ensure effective implementation of the policies in 37.102 .
