According to the FAR conventions at Subpart 1.1, each authority is delegable unless what?

The correct answer highlights an essential principle in federal contracting governed by the Federal Acquisition Regulation (FAR). The FAR establishes that the delegability of authority is presumed, meaning that authorities can generally be delegated unless there is a specific prohibition.

When the FAR states that an authority is "delegable unless specifically stated otherwise," it reinforces the importance of explicit communication regarding the limitations on delegation. This means that if the FAR or other regulations clearly indicate that a particular authority cannot be delegated, then that prohibition must be followed. This helps maintain accountability and ensures that certain critical functions remain within specific roles or positions, safeguarding the integrity of the contracting process.

In contrast, options suggesting that verbal statements, written documentation, or implied practices serve as the basis for establishing non-delegable authority do not align with FAR conventions. Delegated authority must be explicitly documented or stated to ensure compliance and clarity among contracting officials and stakeholders. Therefore, the principle that authority is only non-delegable when explicitly indicated is a fundamental aspect of managing federal contracts effectively.
