systems by incorporating protection, detection, and reaction capabilities.
E2.1.5. Information Exchange Requirements (IERs). The
requirement for information to be passed between and among forces,
organizations, or administrative structures concerning ongoing activities.
Information exchange requirements identify who exchanges what information with
whom, as well as, why the information is necessary and how that information
shall be used.
E2.1.6. Information Superiority. The capability to
collect, process, and disseminate an uninterrupted flow of information while
exploiting or denying an adversary's ability to do the same.
E2.1.7. Information Technology (IT). Any equipment, or
interconnected system or subsystem of equipment, that is used in the automatic
acquisition, storage, manipulation, management, movement, control, display,
switching, interchange, transmission, or reception of data or information by
the executive agency. This includes equipment used by a Component directly, or
used by a contractor under a contract with the Component, which (i) requires
the use of such equipment, or (ii) requires the use, to a significant extent,
of such equipment in the performance of a service or the furnishing of a
product. The term "IT" also includes computers, ancillary equipment, software,
firmware and similar procedures, services (including support services), and
related resources. Notwithstanding the above, the term "IT" does not include
any equipment that is acquired by a Federal contractor incidental to a Federal
contract. The term "IT" includes National Security Systems (NSS).
E2.1.8. Information Technology Architecture (ITA). An
integrated framework for evolving or maintaining existing information
technology and acquiring new information technology to achieve the Agency's
strategic goals and information resources management goals.
E2.1.9. Integrated Architecture. An architecture
consisting of multiple views or perspectives (operational view, systems view,
and technical view) that facilitates integration and promotes interoperability
across Family-of-Systems/System-of-Systems and compatibility among related
mission area architectures.
E22.214.171.124. The operational architecture view is a description
of the tasks and activities, operational elements, and information flows
required to accomplish or support a warfighting function.
E126.96.36.199. The systems architecture view is a description,
including graphics, of systems and interconnections providing for, or
supporting, warfighting functions.
E188.8.131.52. The technical architecture view is the minimal set
of rules governing the arrangement, interaction, and interdependence of
system parts or elements, whose purpose is to ensure that a conformant
system satisfies a specified set of requirements.
E2.1.10. Interoperability. Interoperability is
the ability of systems, units or forces to provide data, information,
materiel, and services to and accept the same from other systems, units, or
forces and to use the data, information, materiel, and services so exchanged
to enable them to operate effectively together. IT and NSS interoperability
includes both the technical exchange of information and the end-to-end
operational effectiveness of that exchange of information as required for
E2.1.11. Joint Mission Areas (JMAs). JMAs
represent a functional group of joint tasks and activities that share a common
purpose, and facilitate joint-force operation and interoperability. JMAs
provide a logical way to organize the Joint Operational Architecture. JMAs
provide the context for defining FoS/SoS relationships sharing a common
E2.1.12. Joint Operational Architecture (JOA).
Description of tasks and activities, operational elements, and information
flows required to accomplish or support military operations; defines types of
information exchanged, frequency of exchange, which tasks and activities are
supported by information exchanges, and nature of information exchanges in
detail sufficient to ascertain specific interoperability requirements.
E2.1.13. Joint Systems Architecture (JSA). The
identification and description of all DoD systems and their interconnections
necessary to accomplish the tasks and activities described in the Joint
E2.1.14. Joint Technical Architecture (JTA). The
JTA provides the minimal set of rules governing the arrangement, interaction,
and interdependence of system parts or elements, whose purpose is to ensure
that a conformant system satisfies a specified set of requirements. The JTA
defines the service areas, interfaces, and standards (JTA elements) applicable
to all DoD systems, and its adoption is mandated for the management,
development, and acquisition of new or modified fielded IT and NSS systems
throughout the Department of Defense.
E2.1.15. Key Performance Parameters (KPPs). Those
capabilities or characteristics considered most essential for successful
mission accomplishment. Failure to meet a KPP threshold can be cause for the
concept or system selection to be reevaluated or the program to be reassessed
or terminated. Failure to meet a Capstone Requirements Document KPP threshold
can be the cause for the FoS/SoS concept to be reassessed or the contributions
of the individual systems to be reassessed.
E2.1.16. Materiel Solution.
Correction of a deficiency, satisfaction of a need, or incorporation of new
technology that results in the development, acquisition, procurement or
fielding of a new item (including ships, tanks, self-propelled weapons,
aircraft, etc., and related software, spares, repair parts and support
equipment, but excluding real property, installations, and utilities)
necessary to equip, operate, maintain, and support military activities without disruption as to its application
for administrative or combat purposes.
E2.1.17. Mission Area Integrated Architectures.
Mission area integrated architectures are the common foundation for mission
area focused, outcome-based IT and NSS interoperability and supportability
processes. Mission area integrated architectures (consisting of operational,
systems, and technical views) are derived from JMAs (i.e.,
subordinate/supporting missions to the JMAs) and/or business/administrative
mission areas. Mission area integrated architectures can cover organizational
entities (e.g., Joint Task Force, Navy Battle Group or Army Brigade). The
Joint Operational Architecture (JOA), the Joint Systems Architecture (JSA) and
the Joint Technical Architecture (JTA) serve as the basis for developing
mission area integrated architectures.
E2.1.18. Mission Critical Information Systems
(MCIS). A system
that meets the definitions of "information system" and "national security
system" in the Clinger-Cohen Act (reference
), the loss
of which would cause the stoppage of warfighter operations or direct mission
support of warfighter operations. (The designation of mission critical should
be made by a Component Head, a CINC or their designee.) A Mission Critical
Information Technology System has the same meaning as a Mission Critical
E2.1.19. Mission Essential Information Systems
system that meets the definition of "information system" in the Clinger-Cohen
Act (reference (b)
), that the acquiring Component Head or
designee determines is basic and necessary for the accomplishment of the
organizational mission. (The designation of mission essential should be made
by a Component Head, a CINC or their designee.)
