Operational NODEs such as ORGANIZATION TYPEs of ORGANIZATIONs and operational roles (a role may be a skill, occupation, occupational specialty, or position). Operational NODEs are independent of materiel considerations; they exist to fulfill the missions of the enterprise, to perform its TASKs, ACTIVITYs, processes, procedures, and operational FUNCTIONs.

As used in the Framework, an ACTIVITY is an action performed in conducting the business of an enterprise. It is a general term that does not imply a placement in a hierarchy (that is, it could be a process or a TASK as defined in other documents and it could be at any level of the hierarchy of the Operational Activity Model). It is used to portray operational actions, not hardware/software system functions. [DoDAF 1.0]	Activity is performed by Node Activity supports Function Activity produces/consumes Information
SYSTEMs including families-of-systems, systems-of-systems, and components (e.g., application software, equipment items). [DoDAF 1.0]	System is employed by Node System allocates Function System processes Data
System FUNCTIONs describe what SYSTEMs do. [DoDAF 1.0]	Function is supported by Activity Function is allocated by System Function sends/receives Data
INFORMATION such as that required to perform TASKs. [DoDAF 1.0]	Information is produced/consumed by Node Information is produced/consumed by Activity Information is conveyed by Data
The related concept to INFORMATION the actual means by which INFORMATION is often conveyed. The concept of DATA pertains to the format and structure, in addition to meaning. DATA may be provided by databases, formatted messages, XML, etc. [DoDAF 1.0]	Data is processed by System Data is sent/received by Function Data conveys Information
