BOX 2.9 The DOD Three-Part Architectural Framework
"a description (often graphical) of the operational elements, assigned tasks, and information flows required to support the warfighter. It defines the type of information [exchanged], the frequency of the exchange, and what tasks are
supported by these information exchanges." The operational architecture is thus the doctrine-driven representation of C4ISR nodes, roles, processes, interrelationships, and data/information exchanges. This representation relates to specific scenarios and joint/combined/coalition mission functions and forms the basis for realistic process and information flow representation and prioritization.
OPERATIONAL ARCHITECTURE --
ARCHITECTURE--"a description, including graphics, of the
systems and interconnections providing for or supporting a warfighting
function. The systems architecture [view] defines the physical connection,
location, and identification of the key nodes, circuits, networks, warfighting
platforms, etc. associated with information exchange and specifies system
performance parameters. The systems architecture [view] is constructed to
satisfy operational architecture component requirements per the standards
defined in the technical architecture."
ARCHITECTURE--"a minimal set of rules governing the
arrangement, interaction, and interdependence of the parts or elements whose
purpose is to ensure that a conformant system satisfies a specific set of
requirements. It identifies system services, interfaces, standards, and their
relationships. It provides the framework upon which engineering specifications
can be derived, guiding the implementation of systems."
