2018 Leadership in Enterprise Architecture Driven Results - Government Project, Defense


Congratulations to:




Headquarters (HQ) Air Mobility Command (AMC) Enterprise Architecture (EA)

Development to Model Based Systems Engineering (MBSE) Solution


This project demonstrated for the command that Enterprise Architecture constructed and translated from levels one, two, and three of “The Zachman Ontology” can then continue the alignment transformation into “The Zachman Framework for Enterprise Architecture”, level four, Engineer Perspective. Applying systems engineering discipline along with SysML provides a more detailed and comprehensive set of requirements and a set of detailed engineering specifications that were not possible with the existing requirements generation processes. Historically, AMC would form a team of functional subject matter experts who would be expected to develop the requirements set in a Microsoft Spreadsheet without the aide a system engineering concepts or tools. The proof-of-concept not only yielded a comprehensive list of requirements / high-level design, but a set of requirements that have traceability to the supported processes and activities at the Enterprise Architecture level. In addition, the use of SysML Block Definition Diagrams provides a way to model man-machine interfaces without trying to mock up a screen face. As a result, along with a list of requirements, the command now has the data (attributes) and screen functions (behavior) allocated to each block (high-level design). This approach provides a very concise way of capturing large amounts of detail in a very efficient way to solve complex requirements generation for hard to solve algorithms for efforts such as diplomatic clearance and airfield suitability applications.

AMC achieves EA discipline by developing standard templates and guidelines that drive development of architecture artifacts. This discipline is based on industry experts in the field of EA, Zachman and Spewak. The discipline focuses on collection, stakeholder collaboration, and standardized storage of enterprise-wide primitives (i.e. information elements, performers, networks, systems, services, business processes) that can be scoped, assembled, and built to create composite models required by the Department of Defense Architecture Framework (DODAF). This approach allows reuse of the individual primitives across segment-, solution-, and enterprise-level architectures developed in support of HQ AMC and the Combatant Command. The enterprise-wide primitives are then used as the baseline library for incorporation into the MBSE effort. Information elements, performers, networks, systems, system functionality, services, and business processes are selected and the scope of the engineering effort is narrowed down to target an identified gap within the enterprise. The enterprise engineering staff used the MBSE methodology to develop Block Definition Diagrams (BDDs), Use Cases, and Use Case diagrams from a logical solution. The enterprise engineers interact with stakeholders, subject matter experts, and program offices to further refine the requirements captured at the EA level until a fully flushed out set of Technology Specification Models is available. These stakeholders view and approve all specifications in real time.
