The focus of an operational assessment is on significant trends noted in development efforts, programmatic voids, areas of risk, adequacy 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. ) N8 K+ J5 C' I% `5 ?- m% P- c: lOperational Availability The degree, expressed in terms of 1.0 as the highest, to which one can expect equipment or weapon systems to work properly when required.
