The document outlines requirements for a contractor's estimating system when submitting proposals to the government. It states that the contractor must disclose its estimating system in writing to the contracting officer and allow it to be protected as privileged information. An acceptable estimating system accurately describes current cost estimating policies and procedures and provides enough detail for the government to evaluate. It must comply with the disclosed system and notify of significant changes. The system should use appropriate data and techniques to prepare, review, and approve estimates and have procedures to update cost estimates during negotiations.
