Other Transaction agreements (OTAs): prototypes, consortia and follow-on production

Other Transactions (OTs) are agreements that are not procurement contracts, grants or cooperative agreements. For DoD, the authority comes from statute: 10 U.S.C. 4021 for research and 10 U.S.C. 4022 for prototype projects, with 10 U.S.C. 4022 also allowing follow-on production. Because OTs generally sit outside the FAR and DFARS, they can be negotiated faster and with terms suited to commercial and nontraditional companies. They are also where much of DoD's prototyping in space, autonomy, cyber and advanced manufacturing happens, often through consortia.

Research, prototype and production#

Prototype OT agreements carry audit and cost-sharing provisions implemented in 32 CFR Part 3. Larger agreements need senior approvals, so expect more process as the dollar value grows.

Who can get a prototype OT#

10 U.S.C. 4022(d) allows a prototype OT only if at least one of these is true:

• At least one nontraditional defense contractor or nonprofit research institution participates to a significant extent
• All significant participants are small businesses or nontraditional defense contractors
• At least one third of the total cost is paid by parties other than the Federal Government
• The senior procurement executive determines in writing that exceptional circumstances justify the OT

A nontraditional defense contractor is an entity that has not performed, for at least the one-year period before DoD solicits sources, any DoD contract or subcontract subject to full coverage under the Cost Accounting Standards (10 U.S.C. 3014). Many traditional primes therefore team with nontraditional companies to qualify, which is why OT teaming is a real market.

Follow-on production#

A prototype OT can lead to a follow-on production contract or transaction without further competition when competitive procedures were used for the prototype project and the participants successfully completed it (10 U.S.C. 4022(f)). The solicitation and the agreement should state that follow-on production is possible. If they do not, the production path becomes harder. Read this part of every OT solicitation and agreement carefully, because it is where a prototype turns into a program.

How OTs are competed#

OT competitions look different from FAR source selections:

• Consortia. Many DoD organizations award OTs through a consortium: a group of companies and research institutions managed by a consortium manager under a base agreement. Members respond to calls with white papers or solution briefs, and awards flow through the manager. Membership has its own fees and terms.
• Commercial Solutions Openings. DoD uses Commercial Solutions Opening style processes (10 U.S.C. 3458) and similar area announcements: a broad problem statement, a short solution brief, a pitch, then a request for prototype proposal.
• Speed. Expect short response windows and quick pivots from paper to pitch.

Protest rights are narrower and less predictable than for FAR contracts, so negotiate carefully up front rather than counting on a protest later.

What still applies#

An OT is not a rules-free zone. The agreement sets the terms, and agencies commonly include requirements for security, cybersecurity, export control, intellectual property and payment milestones. CMMC and DFARS cybersecurity clauses do not apply automatically, but agreements can impose equivalent requirements, and controlled information must still be protected as the agreement and the Government's markings require. See CUI and Zero-CUI practices and ITAR and EAR export controls.

OT readiness checklist#

Common pitfalls#

• Assuming OT means no rules. The agreement can include almost any term, and consortium base agreements add their own.
• Weak intellectual property terms. Giving away data rights at the prototype stage can cost you the production work.
• Missing the follow-on language. No follow-on provision in the solicitation and agreement means no easy path to production.
• Overstating nontraditional status. If your company has CAS-covered DoD work in the look-back period, it is not nontraditional.

How TeamingIndex helps#

• The vehicle catalog includes OT consortia and Commercial Solutions Opening programs alongside FAR-based vehicles, with their known participants.
• Find partners with prototype and research experience, for example by searching the directory for prototype work.
• Use the teaming board to find nontraditional or small business partners that let your team meet a prototype OT condition.
• Pursuing an IDIQ instead? See contract vehicles.
