This IDEF0 diagram example was redesigned from the Wikimedia Commons file: C4ISR Architecture Framework, Example Activity Diagram in IDEF0 Format.jpg. [commons.wikimedia.org/ wiki/ File:C4ISR_ Architecture_ Framework,_ Example_ Activity_ Diagram_ in_ IDEF0_ Format.jpg]
"... the C4ISR concept of Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance ..." [en.wikipedia.org/ wiki/ C4ISR]
"The C4ISR Architectural Framework (C4ISR AF) is now known as DoDAF, is a reference model developed by the US Department of Defense in the 1990s." [commons.wikimedia.org/ wiki/ Category:C4ISR_ Architecture_ Framework]
"The Department of Defense Architecture Framework (DoDAF) is an architecture framework for the United States Department of Defense (DoD) that provides visualization infrastructure for specific stakeholders concerns through viewpoints organized by various views. These views are artifacts for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through tabular, structural, behavioral, ontological, pictorial, temporal, graphical, probabilistic, or alternative conceptual means.
This Architecture Framework is especially suited to large systems with complex integration and interoperability challenges, and it is apparently unique in its employment of "operational views". These views offer overview and details aimed to specific stakeholders within their domain and in interaction with other domains in which the system will operate."

The example "C4ISR architecture framework - IDEF0 activity diagram" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the solution "IDEF Business Process Diagrams" from the area "Business Processes" of ConceptDraw Solution Park.

Basic Flowchart Symbols and Meaning

Flowchart Symbols and Meaning - Provides a visual representation of basic flowchart symbols and their proposed use in professional workflow diagram, standard process flow diagram and communicating the structure of a well-developed web site, as well as their correlation in developing on-line instructional projects. See flowchart's symbols by specifics of process flow diagram symbols and workflow diagram symbols.

The vector stencils library "IDEF0" contains 26 IDEF0 diagram symbols.
Use it for business process modeling with IDEF0 diagrams.
"The IDEF0 model ... is based on a simple syntax. Each activity is described by a verb-based label placed in a box. Inputs are shown as arrows entering the left side of the activity box while output are shown as exiting arrows on the right side of the box. Controls are displayed as arrows entering the top of the box and mechanisms are displayed as arrows entering from the bottom of the box. Inputs, Controls, Outputs, and Mechanisms are all referred to as concepts.
- Arrow: A directed line, composed of one or more arrow segments, that models an open channel or conduit conveying data or objects from source (no arrowhead) to use (with arrowhead). There are 4 arrow classes: Input Arrow, Output Arrow, Control Arrow, and Mechanism Arrow (includes Call Arrow). See Arrow Segment, Boundary Arrow, Internal Arrow.
- Box: A rectangle, containing a name and number, used to represent a function.
- Context: The immediate environment in which a function (or set of functions on a diagram) operates.
- Decomposition: The partitioning of a modeled function into its component functions.
- Fork: The junction at which an IDEF0 arrow segment (going from source to use) divides into two or more arrow segments. May denote unbundling of meaning.
- Function: An activity, process, or transformation (modeled by an IDEF0 box) identified by a verb or verb phrase that describes what must be accomplished.
- Join: The junction at which an IDEF0 arrow segment (going from source to use) merges with one or more other arrow segments to form a single arrow segment. May denote bundling of arrow segment meanings.
- Node: A box from which child boxes originate; a parent box. See Node Index, Node Tree, Node Number, Node Reference, Diagram Node Number." [IDEF0. Wikipedia]
