Who has the authority to waive cost accounting standards on contracts?

The authority to waive Cost Accounting Standards (CAS) on contracts typically rests with the head of the contracting agency or a designated official within the agency. This authority is exercised under specific circumstances, such as when compliance with CAS is not deemed necessary for the contract's performance or when it would be impractical. The waiver process often involves a formal request and justification to ensure that the decision aligns with regulatory guidelines.
