C5 OTA Consortium

C5 OTA  •  Consortium for Command, Control and Communications in Cyberspace

C5 assists Department of Defense program managers rapidly identify, acquire, demonstrate and transition innovative technologies to the Warfighter through the use of Other Transaction Agreements (OTAs). These instruments are not standard procurement contracts, grants or cooperative agreements, and therefore are not subject to most provisions of the Federal Acquisition Regulation (FAR). C5 comprises nearly 1,000 leading technology companies, nonprofits and academic institutions and is the largest single OTA consortium.

This scale enables greater reach, more robust competition and a broader range of technology solutions available to the Government. C5’s current OTA features a flexible, on-demand solicitation to process that can be tailored to match unique project requirements and acquisition strategies.

How It Works

Consortium Management Group (CMG) serves as both the consortium manager and administrator of the OTA for C5, providing an independent, transparent single interface between members and the Government. At any time throughout the year, Government program managers identify their funded needs and request technology solutions from C5. CMG facilitates the solicitation process and works with each interested member to ensure that government expectations are met and statutory compliance is maintained. The Government evaluates the responses and selects the solution(s) that best meet its need. The selected member(s) collaborates with the Government to establish a Statement of Work and negotiates the price. CMG then awards a sub-agreement to the member(s) for performance of the project.
