Policy Highlights

The NDIA Policy team monitors, advocates for, and educates government stakeholders on, policy matters of importance to the defense industrial base.  Our mission is to ensure the continued existence of a viable, competitive national technology and industrial base, strengthen the government-industry partnership through dialogue, and provide interaction between the legislative, executive, and judicial branches. The Policy team also represents NDIA in several inter-association groups representing the defense industry and the government contracting community including the Council of Defense and Space Industry Associations (CODSIA), the Acquisition Reform Working Group (ARWG), and the Industry Logistics Coalition (ILC).

Over the past three years, the Policy team has led NDIA’s Acquisition Reform Initiative. This effort has provided legislative recommendations to assist Congressional acquisition reform efforts, many of which were enacted or influenced final provisions in the Fiscal Year 2016 and Fiscal Year 2017 National Defense Authorization Acts. Policy staff regularly meets with key policy stakeholders, and manages Congressional interaction with NDIA Chapters and Divisions.

    Budgets Require Industry-Government Cooperation

    September, 2019

    We should all celebrate the recent passage and signing of the 2019 Bipartisan Budget Act that ended the federal budget impasse and did away with the destructive spending caps imposed by the 2011 Budget Control Act. Thankfully, the way legislators wrote the budget deal and its two-year coverage means the threat of sequestration has finally passed.
