Department of Homeland Security 'U.S. Customs and Border Protection' Budget Overview: Fiscal Year 2021, Congressional Justification [open pdf - 6MB]
From the Component Overview: "The strategic context presents the performance budget by tying together programs, or PPAs [programs, projects and activities], and performance measures that gauge the delivery of results to our stakeholders. The Common Appropriation Structure (CAS) allows DHS to integrate the programmatic view and a significant portion of the Level 1 PPAs represent what DHS refers to as our mission programs. A mission program is a group of activities acting together to accomplish a specific high-level outcome external to DHS and includes operational processes, skills, technology, human capital, and other resources. CBP's [U.S. Customs and Border Protection] mission programs are presented below. Performance measures associated with these programs are presented in two measure sets, strategic and management measures. Strategic measures communicate results delivered for our agency goals by these programs and are considered our Government Performance and Results Act Modernization Act of 2010 (GPRAMA) measures."
