Select the type of Operational Test and Evaluation assessment conducted on prototype systems in the TMRR phase.

The Early Operational Assessment is specifically designed to evaluate prototype systems developed during the Technology Maturation and Risk Reduction (TMRR) phase. This type of assessment focuses on providing feedback on the system’s operational capabilities, helping identify potential issues and operational limitations early in the development process.

In this phase, the evaluation is critical as it informs decision-makers about how well the prototypes meet user requirements and operational needs, thereby guiding future refinements. By conducting the Early Operational Assessment, program managers and stakeholders gain insights into the system's performance before significant investments are made in full-scale production.

This assessment is aligned with the objectives of the TMRR phase, which is to reduce risks associated with technology development and to ensure that the prototypes can meet the anticipated operational capabilities with minimal modifications later in the life cycle. Other assessments mentioned, such as the Initial Operational Test and Follow-on Operational Test, occur at later stages in the acquisition process when systems are more mature and have already undergone significant development.
