The U.S. Air Force tasked Intergraph Corporation to integrate a standard Department of Defense accounting system into the Air Force Materiel Command (AFMC) legacy production, material, and financial systems. This system interfaces with 30 different Air Force and Defense Finance and Accounting Service (DFAS) legacy systems. The challenge was to complete the interface while minimizing any changes or impacts to each system involved.Intergraph personnel created an integration engine – a suite of applications responsible for scheduling and executing data exchanges between the legacy systems. After analyzing data from the legacy systems, Intergraph prepared formal system design specifications and detailed design documentation, creating a comprehensive implementation plan.
Using a structured configuration management approach, Intergraph documented all requirements and control changes, ensured controlled access to sensitive financial data, tested system performance throughout the design process, and conducted a formal site integration test.
The DFAS middleware solution significantly reduced required system changes to the DFAS legacy accounting systems. By reducing those changes, DFAS will save years in development time and millions of dollars in system modification costs.
