The Systems Modeling Language (SysML) and DoDAF implemented in the Unified Architecture Framework (UAF) provides powerful capabilities. In addition to the standard DoDAFviewpoints of Capability, Operational, Services, Systems, Projects, Standards, and Data/Information, the UAF has added Personnel , Security, Requirements, Parametrics, and extensions to the Services viewpoints. The UAF combined with SysML in an MBSE ecosystem enables engineers to specify, design, analyze, verify and implement MOSA architectures.
