Center for Procurement Advocacy

The Center for Procurement Advocacy (“CPA”) works with key stakeholders in the Executive and Legislative Branches to advance Federal procurement law and policy matters.  It provides a venue where its members may collaborate, develop, and advocate for consensus-based policy positions that seek to promote the aligned interests of government and industry, and that safeguard the integrity of the nation’s defense and civilian industrial bases.  The organization also offers a forum for regular stakeholder engagement in furtherance of government-industry partnership.

The CPA is grounded in the following principles to advance the Federal acquisition system:

  • Honesty and integrity in Federal acquisition
  • Processes that are understood, credible, applied fairly, and administratively efficient
  • Collaboration between government and industry to promote constant improvement in the fulfillment of the government’s mission
  • The fulfillment of the government’s mission with commercial products and services to the maximum extent practicable
  • The use of competitive procedures in a solicitation process that leverages full and open competition
  • A transparent contract award and administration process that manifests compliance with the law and provides for the redress of vendor grievances
  • The empowerment of acquisition officials to advance their missions

Membership in the CPA is open to Coalition members only. To learn more about CPA membership and activities, contact CPA Executive Director Tim Cook at
