Other Transaction Agreements (OTAs) have evolved from specialized acquisition instruments into a significant component of federal defense procurement. A newly released Department of Defense guide suggests their role is about to become even more important.
On October 14, 2026, DoD issued Guide to Prototype Other Transactions, Version 1.0, through the Office of the Under Secretary for Acquisition and Sustainment. The guide addresses the planning, solicitation, negotiation, award, administration, and follow-on production of prototype Other Transactions under 10 U.S.C. § 4022.
Its most consequential statement is a policy preference: DoD favors Other Transactions over traditional FAR-based procurement contracts when the statutory criteria for their use are satisfied.
This represents a significant acquisition-policy signal, particularly for commercial technology companies, small businesses, and nontraditional defense contractors.
The financial scale is already considerable. According to the Government Accountability Office, federal agencies reported approximately $18.2 billion in Other Transaction obligations during fiscal year 2025. Separately, GAO documented that DoD’s prototype and production OTA obligations had grown from approximately $1.8 billion in fiscal year 2016 to more than $18 billion in fiscal year 2024.
The new guide addresses several persistent misconceptions about OTAs.
First, Other Transactions are legally enforceable contracts.
Although OTAs are not FAR procurement contracts, they are binding agreements. Their flexibility does not eliminate contractual obligations or the importance of negotiating intellectual property, payment milestones, cost sharing, termination, disputes, liability, and performance requirements.
Indeed, the absence of standard FAR clauses can make careful negotiation more important because contractors cannot necessarily rely upon the familiar rights and remedies available under traditional federal procurement contracts.
Second, OTA flexibility does not eliminate competition.
The Competition in Contracting Act does not directly apply to prototype OTAs. Nevertheless, 10 U.S.C. § 4022 requires competitive procedures to the maximum extent practicable.
That distinction becomes especially important when an agency anticipates follow-on production.
Under § 4022(f), a successful prototype may transition to a production contract or transaction without further competition when the statutory conditions are satisfied, including competition in selecting the original prototype participants and successful completion of the prototype.
For contractors, the initial prototype opportunity can therefore carry substantial strategic value beyond its immediate funding.
Third, companies do not have to participate through a consortium to receive an OTA.
The guide confirms that awards may be structured with individual companies, joint ventures, partnerships, consortia, or prime contractors using subcontractors.
Consortia remain important because they can connect DoD with specialized technologies and suppliers that might otherwise struggle to access federal procurement opportunities.
But the guide also emphasizes increased transparency.
Government prototype and follow-on production OT awards must be reported through the Federal Procurement Data System. For consortium arrangements, reporting procedures are intended to identify the actual companies receiving Government awards and performing project work rather than relying exclusively on the identity of the consortium manager.
This development is particularly relevant because GAO previously identified weaknesses in DoD’s ability to determine which companies actually received consortium-based awards, limiting the Department’s capacity to assess whether OTAs were successfully expanding participation by nontraditional contractors and small businesses.
Fourth, an OTA is not automatically faster than a FAR contract.
The guide expressly dispels that misconception. Speed depends on acquisition planning, appropriate use of flexibility, effective negotiations, and timely decision-making—not simply the legal instrument selected.
For contractors, the practical implications extend across the acquisition lifecycle.
Companies pursuing OT opportunities should understand the statutory eligibility requirements before developing a proposal; evaluate whether consortium participation provides a meaningful advantage; negotiate technical-data and intellectual-property provisions carefully; and establish clear, measurable prototype success criteria.
They should also evaluate follow-on production from the beginning. Manufacturing capacity, financing, supply-chain resilience, pricing, and scalability can become decisive once a prototype succeeds.
The broader lesson is straightforward.
DoD is increasingly treating Other Transactions as a preferred acquisition pathway, not merely an exception to traditional contracting.
For federal contractors, understanding OTAs is becoming an essential competitive capability.
But the greatest opportunity may not be winning an initial prototype award. It may be structuring that award so successful technology can transition into sustained production and long-term government business.

Other Transactions are governed by applicable statutory authority, agency policy, and the terms of the individual agreement.
