A valid unsolicited proposal must-
- Be innovative and unique;
- Be independently originated and developed by the offerer. Unsolicited proposals in response to a publicized general statement of agency needs are considered to be independently originated;
- Be prepared without Government supervision, endorsement, direction, or direct Government involvement;
- Include sufficient detail to permit a determination that Government support could be worthwhile and the proposed work could benefit the agency’s research and development or other mission responsibilities;
- Not be an advance proposal for a known agency requirement that can be acquired by competitive methods, and
- Not address a previously published agency requirement.
