Defense Acquisition Board

The Defense Acquisition Board (DAB) is the principal senior advisory body in the Department of Defense that reviews major defense acquisition programs at milestone decision points and other key events, making recommendations to the Under Secretary of Defense for Acquisition and Sustainment (USD(A&S)), who serves as the Defense Acquisition Executive and the Milestone Decision Authority for the most significant programs.

What is the Defense Acquisition Board?

The DAB was established as part of the Packard Commission reforms of the 1980s, which restructured DoD acquisition oversight after congressional investigations into program cost growth and performance failures. The DAB provides a cross-functional senior leadership review mechanism ensuring that major programs receive scrutiny not just from the sponsoring military service, but from the full range of OSD (Office of the Secretary of Defense) stakeholders.

The DAB is chaired by the USD(A&S) and includes senior officials from the Joint Chiefs of Staff, the military services, CAPE (Cost Assessment and Program Evaluation), DOT&E (Director, Operational Test and Evaluation), and other OSD offices. For MDAP reviews, the DAB typically convenes as part of the milestone decision process, the program executive officer and program manager brief the DAB on program status, test results, cost estimates, and risk before the milestone decision is made.

DAB reviews are not limited to formal milestones. "Special Interest" designations trigger additional DAB oversight on programs experiencing significant cost growth, schedule delays, or technical problems. The DAB may conduct interim reviews, impose special reporting requirements, or recommend program restructuring.

For defense contractors, understanding the DAB and its role in program decisions is important context. When a program undergoes DAB review, particularly a special interest review triggered by program problems, contracting activity may slow or halt pending the DAB's findings and recommendations. If the DAB recommends restructuring, the contractor may face contract modifications, scope changes, schedule adjustments, or in extreme cases a program cancellation affecting existing contract awards.

Why the Defense Acquisition Board matters for defense contractors

The DAB controls the pace and scope of major defense program decisions. Programs under special DAB scrutiny are at elevated risk of restructuring, delay, or cancellation, all of which directly affect contractor revenue and program continuity.

Example

A prime contractor's $3.2B MDAP program comes under DAB special interest review after the latest Selected Acquisition Report (SAR) shows a 25% cost growth from the original Milestone B baseline. The DAB convenes a special review, during which the program manager must justify the cost growth, present a revised program plan, and address developmental testing anomalies. The DAB recommends a program restructure that reduces the production quantity from 240 to 180 systems and extends the LRIP phase by 18 months. The contractor revises its long-range financial projections accordingly and begins discussions with its tier-1 subcontractors about schedule adjustments.

Frequently Asked Questions

Does the DAB approve every defense contract?

No. The DAB reviews only major defense acquisition programs (MDAPs) at key decision points. The vast majority of federal contracts, including many large defense contracts, are awarded below the MDAP threshold and never go through DAB review. DAB oversight is reserved for programs with expected costs exceeding $480M in R&D or $2.79B in procurement.

What is the difference between the DAB and the Service Acquisition Executives?

The DAB and its associated decision authority (USD(A&S)) govern programs designated as MDAPs, the largest and most complex defense programs. The Service Acquisition Executives (SAEs), Army ASA(ALT), Navy ASN(RDA), Air Force SAF/AQ, serve as MDA for programs below the MDAP threshold and for some MDAPs delegated by the USD(A&S). Most defense programs are managed under SAE authority without DAB involvement.

What is a Selected Acquisition Report (SAR)?

A Selected Acquisition Report (SAR) is a congressionally mandated quarterly and annual report on MDAP cost, schedule, and performance that programs must submit when they exceed certain cost growth thresholds. SARs are public documents (available from the Pentagon's Comptroller website) and are a primary public data source on MDAP program health. Contractors can track SAR filings for programs they support to understand how the government is assessing program performance and cost trends.

Can DAB decisions be appealed?

The DAB is an advisory body to the USD(A&S); its recommendations are advisory, not binding. The USD(A&S) makes the actual milestone or acquisition decisions. There is no formal appeal process for DAB recommendations; however, program advocates within DoD can engage the process through the normal decision-making chain. Congressional oversight provides an additional check, committees with jurisdiction over defense appropriations and authorization have historically intervened to preserve programs that DAB recommended reducing or cancelling.
