The focus of an operational assessment is on significant trends noted in development efforts, programmatic voids, areas of risk, Q" O i8 T eadequacy of requirements, and the ability of the program to support adequate operational testing. Operational assessments may be made at any time using technology demonstrators, prototypes, mockups, engineering development models, or simulations but will not substitute for the independent operational test and evaluation necessary to support full production decisions.

Operational . m, c: [: U; yControl (OPCON) Transferable command authority that may be exercised by commanders at any echelon at or below the level of combatant command. Operational control is inherent in Combatant Command (command authority) and is the authority to perform those functions of command over subordinate forces involving organizing and employing commands and forces, assigning tasks, designating 2 v$ v1 \3 e8 Z9 `0 Z7 F% Vobjectives, and giving authoritative direction necessary to accomplish missions assigned to the command. Operational control should be exercised through the ) T! R1 ^+ W7 V' o, Ycommanders of subordinate organizations; normally this authority is exercised through the Service component commanders. Operational control normally 3 @- J6 Z2 U) K* m/ `5 Cprovides full authority to organize commands and forces and to employ those ' [7 `2 f2 f' X i4 @forces, as the commander in operational control considers necessary to accomplish assigned missions.
