The self-assessment shall be submitted not later than 5 working days after the end of each evaluation period. The self-evaluation shall not exceed 1 page per PRS element.

The Contractor shall respond to any complaints and/or ratings of poor performance within five (5) calendar days, after receipt of the report.

7.3 COR Recommendation. The COR will consider all evaluations and any other pertinent information, including Contractor self-assessment, and will prepare a report to the Contracting Officer with findings and recommendations.

7.4 Payment Determination. The Contracting Officer may meet with the COR to discuss the COR's report. The Contracting Officer will make a final determination in writing as to the percentage of work successfully completed, and the resulting payment to be made. A copy of the determination will be provided to the Contractor no later than 45 calendar days after the end of the period being evaluated. All Contracting Officer decisions regarding payment re-calculations are unilateral decisions made solely at the discretion of the Government.

7.5 Payment Re-Calculations. Notwithstanding any other clause of this contract, payment re-calculations will be made within the later of 60 days after the end of the evaluation period or 30 days after receipt of an approved invoice.

7.6 The Quality Assurance Surveillance Plan is one evaluation method the government uses to conduct surveillance performance and to determine whether the Contractor meets the standards of performance as defined in the PWS. The absence of a QASP for any contract requirement, however, shall not detract from its enforceability or limit the rights or remedies of the government under any other provision of the contract in determining the quality of the Contractor performance.
