Which organization provides the priority for mandatory sources of supply?

The General Services Administration (GSA) is the organization responsible for providing the priority for mandatory sources of supply. This role is critical as the GSA establishes policies and guidelines that federal agencies, including the Department of Defense, must follow when procuring goods and services. The guidelines are designed to ensure that federal procurement supports the economy and utilizes government resources efficiently and effectively.

In this context, mandatory sources of supply may include federal supplies and services that meet specific needs and are made available to all federal agencies. The GSA's leadership in sourcing affects the procurement process significantly, as it helps streamline operations and adhere to regulations that promote the use of these mandated sources.

Choosing the GSA highlights an understanding of federal procurement structures and the importance of sourcing mandates for maintaining efficiency and compliance across government entities.
