The focus of an operational assessment is on 1 C& h5 }+ Z" Asignificant trends noted in development efforts, programmatic voids, areas of risk, adequacy of requirements, and the ability of the program to support adequate operational testing.

' g" Y: @, Y6 h+ x7 m: ZOperational Control (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 ( @/ \/ n7 D* n" W# w9 Z; Morganizing and employing commands and forces, assigning tasks, designating objectives, and giving authoritative direction necessary to accomplish missions assigned to the command. Operational control should be exercised through the commanders of subordinate organizations; normally this authority is exercised through the Service component commanders. Operational control normally 6 ]2 Q2 @# U7 r1 `, ^$ x( oprovides full authority to organize commands and forces and to employ those forces, as the commander in operational control considers necessary to $ S& s+ p/ X8 v- Laccomplish assigned missions. Operational control does not, in and of itself, # N4 U+ E- z8 minclude authoritative direction for logistics or matters of administration, discipline, internal organization, or unit training. Operational Effectiveness The overall degree of mission accomplishment of a system when used by representative personnel in the environment planned or expected (e.g., natural, - V% ]1 e6 }$ j% i% q.

PEP, a systems and planning engineering approach, assures that an item can be produced in the required quantities and in the specified time frame, efficiently and economically, and will 0 A( e/ c; r, smeet necessary performance objectives within its design and specification constraints. As an essential part of all engineering design, it is intended to identify potential manufacturing problems and suggest design and production changes or schedule trade-offs, which would facilitate the production process.
