MDA Success Story
Conquest, Inc. and Popkin, Inc. provide enterprise architecture solution
In 1999, Conquest began working with a major federal intelligence agency that collects, synthesizes and analyzes information, then distributes it to other agencies. The client's goal was to develop an enterprise architecture that would help them improve their technology planning at the enterprise level. The agency faced a simple, if challenging goal: defining current technology programs and future technology development so that it could (a) make better decisions about systems acquisition or development and (b) use it as a capital planning system for making budget decisions.
Regulatory pressures also drove some aspects of the project. The Clinger-Cohen Act (1996) and recent Office of Management and Budget (OMB) mandates require that agencies be accountable for technology expenditures to secure funding. The agency was required to support the Dept. of Defense Architectural Framework (DoDAF) (formerly C4ISR) , a standard framework that the DoD had mandated affiliated agencies use. The DoDAF was a brand new guideline when the project began and the first version left a lot of latitude for interpretation.
As enterprise architecture experts, Conquest plays a key role acting as a lead contractor for product/view definitions and functional knowledge. Conquest acts as part of a larger team offering domain insight/experience as well as modeling/enterprise architecture experience. At the start of the project, the contractors worked with the agency to understand some unique requirements for its architecture, including:
Conquest began its involvement by focusing on the functional analysis of the core mission. They talked with domain experts (data gatherers, information manipulators and information producers) as well as system architects and agency management. Architects began by developing the approach to modeling the enterprise, reviewing and selecting the appropriate tools and methods and then architecting the models by interpreting DoDAF guidelines and agency goals.
In the end, Conquest recommended a comprehensive modeling strategy for building the architecture by defining which views were to be used, in which order, which diagram types and architectural elements to include, how to achieve concordance and how to interpret the DoDAF framework guidelines. Conquest also defined the "to be" architecture. In addition, the customers and subject matter experts were encouraged to vet (examine and appraise) the models.
"System Architect helps users understand how all the pieces of this complex environment fit together through building a comprehensive enterprise architecture," said Tom Dalpini, senior architect, Conquest Inc. "We were able to choose the best modeling approach for the goals we were trying to achieve because the tool was so flexible in supporting a wide variety of modeling techniques."
System Architect's built-in flexibility enables Conquest to easily customize the views to the unique needs of the agency. For example, using System Architect's USRPROPS (user properties) feature, architects can add fields/attributes for any diagram or object and add non-standard architecture elements to a diagram (such as observations for a diagram). Most importantly, System Architect's built-in concordance allows team members to update individual models and have confidence that the changes are reflected throughout the architecture. To help users share data and views, System Architect supports a server-based central repository. In addition, diagrams can be exported from System Architect into PowerPoint, Word or Excel for review and approval.
"System Architect makes it easy to document how information flows within an organization," said Dalpini. "An enterprise architecture in a strong modeling tool like System Architect offers an ideal communication vehicle for the many people involved--contractors and internal business process and IT teams-to communicate, collaborate and keep the organization on track."
Conquest's architecture design helped the agency begin to understand its future operations and processes. Model-driven architecture helped facilitate communication by graphically representing vast amounts of data into discrete views that could be reviewed and understood across different organizational groups and business areas. Modeling also encouraged collaboration between groups, helping them identify redundant and non-mission enhancing activities, and driving significant cost savings. To help federal agencies jumpstart their development process, Popkin now offers an integrated DoDAF option for System Architect.
The agency views the project as a wise long-term investment. The architecture has been embraced by its sub-organizations and customers, fostering communications and a shared drive to meet business goals. In the long term, the architecture will enable the agency to make better budget decisions on current and future technology programs. Eventually, groups will need to show how their technology fits into the enterprise architecture before receiving funding. Conquest will continue to play a key role in the entire life of the architectural effort, providing leadership in the areas of modeling the business and providing functional expertise.
System Architect & Model-Driven Architecture
Relationships between levels are used to determine the inter-level source of an object, the inter-level potential impact or similar relationships. In the transition between PIM and PSM levels, System Architect provides the ability to either continue to work in System Architect on the PSM using UML or to transfer to another development tool using XMI.
