"BPM life-cycle.
Business process management activities can be grouped into six categories: vision, design, modeling, execution, monitoring, and optimization.
Functions are designed around the strategic vision and goals of an organization. Each function is attached with a list of processes. Each functional head in an organization is responsible for certain sets of processes made up of tasks which are to be executed and reported as planned. Multiple processes are aggregated to function accomplishments and multiple functions are aggregated to achieve organizational goals." [Business process management. Wikipedia]
The arrow donut chart example "BPM life cycle" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Circular Arrows Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.

"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."

"Your global account (also called unified login or SUL/ single user login) is your single username reserved across all Wikimedia projects (except some special wikis). This gives you a consistent identity throughout Wikimedia, enables features like global user pages, reduces vectors for impersonation, and lets you visit many projects without manually logging in on each wiki."
