(a) Payment limitations. To facilitate timely proposal submission and price definitization, contracting officers should establish initial funding available for interim financing and payments (e.g., progress payments, interim delivery payments (DFARS 232.102-70), public vouchers, and DD250s) consistent with the estimated amounts of contractor expenditures as of the dates specified in the definitization schedule for submission of a qualifying proposal and for price definitization. The contracting officer should subsequently relax or tighten such controls and incentives (e.g., by revising interim billing rates, reducing or suspending progress payments (DFARS 232.503-6), etc.) as necessary and appropriate to achieve timely definitization.
(b) Delivery schedule. Specify a firm delivery schedule, otherwise a "not to exceed" schedule reflecting the Government's minimum needs. A tentative schedule permitting the unilateral contract extension of the delivery schedule shall not be used.
(93) The contracting officer shall identify and include with any delegation of an undefinitized delivery order (BOA, IDC, T&M contract, etc) or other UCA for definitization by the cognizant ACO, any independent Government estimate ("should cost") that have been performed and found useful for determining price reasonableness, establishing negotiation objectives, and for contract negotiations. The delegation letter should request that the ACO furnish feedback on the utility and effectiveness of the IGE to the Center and to office(s) preparing and furnishing the IGE.
