Could you please provide me with the source of the information provided by slide 38 of lesson 21 of ACQ101?
This slide was created a few OMB/CCA/DODD/I 5000 versions ago based on definitions within OMB Circular A-130 and Clinger-Cohen Act (CCA) (now Title 40) and DODI 5000.2 (now 5000.02).
Open full Question Details
The OMB Circ A-130 is the AUTHORITATIVE source for these definitions since it is the highest policy-level guidance. The DODI5000.02 supports the OMB. Both support the LAW--CCA/Title 40. Back in those days, it was extremely important to differentiate between Weapons SW, C4ISR SW and AIS SW; it still is even though all three domains are NOW interconnected (they weren't in those days). It was extremely important to differentiate between Mission Critical and Mission Essential//between what's important to combat missions (National Security) and non-combat (No Impact on National Security). We still have those differentiations and they are delineated in the OMB Circ A-130 (OMB's directive on HOW TO MANAGE IT/SW in all Agencies) and then reinforced in the DODI 5000.02 (which is the current interpretation of the Clinger-Cohen Act/Title 40 (Law)).
The following are the current definitions:
From OMB Circular A-130
u.The term "major information system" means an information system that requires special management attention because of its importance to an agency mission; its high development, operating, or maintenance costs; or its significant role in the administration of agency programs, finances, property, or other resources.
v.The term "national security system" means any telecommunications or information system operated by the United States Government, the function, operation, or use of which (1) involves intelligence activities; (2) involves cryptologic activities related to national security; (3) involves command and control of military forces; (4) involves equipment that is an integral part of a weapon or weapons system; or (5) is critical to the direct fulfillment of military or intelligence missions, but excluding any system that is to be administrative and business applications (including payroll, finance, logistics, and personnel management applications). The policies and procedures established in this Circular will apply to national security systems in a manner consistent with the applicability and related limitations regarding such systems set out in Section 5141 of the Clinger-Cohen Act (Pub. L. 104-106, 40 U.S.C. 1451). Applicability of Clinger-Cohen Act to national security systems shall include budget document preparation requirements set forth in OMB Circular A-11. The resultant budget document may be classified in accordance with the provisions of Executive Order 12958.
From Title 40, Clinger-Cohen Act: (NOTE: CCA/Title 40 has the same language as DODI 5000.02); The DODI 5000.02 directly supports the CCA and OMB Circ A-130.
Mission-Critical Information System: A system that meets the definitions of "information system" and "national security system" in the Title 40/CCA (Reference (n)), the loss of which would cause the stoppage of warfighter operations or direct mission support of warfighter operations. (Note: The designation of mission critical shall be made by a Component Head, a Combatant Commander, or their designee. A financial management IT system shall be considered a mission-critical IT system as defined by the Under Secretary of
Defense (Comptroller) (USD(C)).) A "Mission-Critical Information Technology System" has the same meaning as a "Mission-Critical Information System."
Mission-Essential Information System: A system that meets the definition of "information system" in Reference (n), that the acquiring Component Head or designee determines is basic and necessary for the accomplishment of the organizational mission. (Note: The designation of mission essential shall be made by a Component Head, a Combatant Commander, or their designee. A financial management IT system shall be considered a mission-essential IT system as defined by the USD(C).) A "Mission-Essential Information Technology System" has the same meaning as a "Mission-Essential Information System."
