Other Transaction Agreements
ATI has extensive experience and expertise in the Other Transaction consortium business model.
Other Transaction (OT) Agreements reduce contractual burdens traditionally associated with federal contracting, making it easier for nontraditional companies—including small and emerging businesses—to participate in technology development.
The OT consortium model creates an enterprise partnership between the Government and technology providers within a specific mission or technology domain, fostering collaboration while streamlining many traditional contracting requirements.
ATI has extensive experience managing OT collaborations. Our successful application of the OT consortium model has helped demonstrate its value across Government, and we continue to lead the field in consortium management.

OTA Resources
- OTAs authorized by 10 U.S. Code § 4021 (formerly 2371) are applicable for basic, applied, and advanced research projects to pursue development and application of dual-use technology. Unlike Prototype OTAs, Research OTAs do not include authority for transition to follow-on production contracts or transactions. Research OTAs require cost sharing arrangements between the Government and the other party/parties, typically split 50/50, although the ratio is negotiable based on resources, previous technological investments, commercial vs. Government applicability, performance risk, and nature of a project. Although the Competition in Contracting Act (CICA) is not applicable, competition should be pursued to the maximum extent practicable to incentivize high quality and competitive pricing.
- DoD Policy: Defense Procurement and Acquisition Policy, within the Office of the Secretary of Defense, is the DoD point of contact for questions about the DoD policy regarding use of OTAs to carry out prototype projects. Email the Office of the Deputy Director, DPAP, Contract Policy and International Contracting, regarding OTAs to carry out prototype projects

- OTAs authorized by 10 U.S. Code § 4022 (formerly 2371b) are appropriate for research and development and prototyping activities to enhance mission effectiveness of military personnel and supporting platforms, systems, components, or materials. Prototype OTAs may only be used to develop limited quantities of prototypes, however, they can provide a path to directly award a follow-on Production OTA or contract without having to recompete the effort. This is an important benefit of the Prototype OTA approach, but programs must develop acquisition approaches for prototype projects that address anticipated follow-on activities to properly take advantage of this authorization and also ensure the organization is prepared and resourced to move forward with a successful prototype OTA.
