"ONA does not agree that every contract requires exhaustive or significant verification of the methods used to derive analytic content," the office said. "ONA quality control measures will be dictated by ONA requirements and the statement of work. Deliverables are reviewed and accepted based on the quality of the work and in accordance with the terms of the contract. Consistent with this practice, deliverables were reviewed and assessed for the four contracts audited by the DoD OIG. The Government received deliverables that were high quality and conformed to the requirements set forth in the contract. The Government determined that the contractor performed satisfactorily."
