48 CFR 44.304: 44.304 Surveillance.

(a) The ACO shall maintain a sufficient level of surveillance to ensure that the contractor is effectively managing its purchasing program.

(b) Surveillance shall be accomplished in accordance with a plan developed by the ACO with the assistance of subcontracting, audit, pricing, technical, or other specialists as necessary. The plan should cover pertinent phases of a contractor's purchasing system (preaward, postaward, performance, and contract completion) and pertinent operations that affect the contractor's purchasing and subcontracting. The plan should also provide for reviewing the effectiveness of the contractor's corrective actions taken as a result of previous Government recommendations. Duplicative reviews of the same areas by CPSR and other surveillance monitors should be avoided.
