What's In An IT Acronym

In the military and public safety world, information technology is often discussed in broader strategic and operational terms.

For example, in the Coast Guard, it is referred to as C4&IT--Command, Control, Communication, Computers and Information Technology.

In the Department of Defense, they often use the term C4ISR--Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance.

According to GovTech Magazine, some public safety agencies (i.e. law enforcement and firefighting) often use another version of this, namely 4CI--Command, Control, Communications, Computers, and Intelligence.

The article provides some simple straightforward definitions for these (although perhaps skewed for first responders), as follows:

"- Command: The authority and responsibility for effectively using available resources, and for organizing, directing, coordinating and controlling personnel and equipment to fulfill a mission.

- Control: The ability to issue orders or directions, with the result that those directions are carried out.

- Communications: The most essential element. Communications between responders on the ground and command staff are critical to ensure that both groups have a common operating picture of the situation.

- Computers: They process, display and transport information needed by commanders, analysts and responders. Today this increasingly includes mobile devices, such as laptops and smartphones.

- Intelligence: The product of the collection, processing, integration, analysis, evaluation and interpretation of all available relevant information."

While these capabilities are all critical to mission performance, I am not sure why we have all these variations on the same theme, but at least, we all agree on the 4Cs or is it C4?

Enterprise Architecture Terms and Taxonomy

A key foundation to developing enterprise architecture is getting the EA terms and taxonomy right for the organization, so that there is a common language and understanding by business and technical subject matter experts of what all things EA means.

Here are some fundamental terms and a high-level taxonomy for them (prior to having these, I found considerable confusion in the enterprise as to what many of these terms meant and they were used incorrectly and interchangeably by various users):

1) C4&IT—Any equipment or interconnected system or subsystem of equipment, or techniques used in the automatic acquisition, storage, manipulation, management, transmission, or reception of digital, voice, or video data or information to the appropriate levels of command. This includes command and control, networks, common operational picture systems, information assurance services, communication products and standards, computers, ancillary equipment, software, firmware, procedures, services (including support services) and related resources. (short definition─Command, Control, Communications, Computers, and Information Technology)

2) FISMA Systems—An application or general support system that meets the requirements of the Federal Information Systems Management Act (FISMA) of 2002, including completion of certification and accreditation, risk assessments, policies, and procedures, security plans, security awareness training, annual security testing, remediation procedures, incident response procedures, and contingency plans. (short definition—systems as defined by FISMA).

a. Application Systems—A discrete set of information resources [i.e. applications] organized for the collection, processing, maintenance, use, sharing, dissemination, or disposition of information. (short definition—one or more applications).

i. Applications—the use of information resources (information and information technology) [i.e. hardware, software, and database] to satisfy a specific set of user requirements. (short definition—combination of hardware, software, and database).

b. General Support Systems—An interconnected set of information resources under the same direct management control that share common functionality. It normally includes hardware, software, information, data, applications, communications, and people [i.e. infrastructure]. (short definition—IT infrastructure).

3) Products and Standards

a. Products—Includes hardware, the physical parts of a computer system, and software, the programs or other “instructions” that a computers needs to perform specific tasks.

b. Standards-- Guidelines that reflect agreement on products, practices, or operations by nationally or internationally recognized industrial, professional, trade associations, or government bodies.

The way to read the taxonomy is that C4&IT at the top is the CIO world of work and it is composed of Command, Control, Communication, Computers, and IT. C4&IT decomposes to FISMA Systems (since all systems must be FISMA compliant). FISMA Systems decompose to Application Systems (and their applications) and General Support Systems (infrastructure). And these systems (applications systems and general support systems) decompose into hardware and software products and standards.

The short working definitions are fairly straight forward and the longer definitions are based on public information definitions from National Institute of Science and Technology (NIST), Office of Management and Budget (OMB), The Department of Homeland Security (DHS), and The Department of Defense (DOD).

These terms and taxonomy should help enterprise architects and their users differentiate C4&IT, Systems, Application Systems, General Support Systems, Products, and Standards, and maybe even widgets by inference. :-)
