The National Geospatial-Intelligence Agency (NGA) has implemented an integrated facilities' management program covering its many buildings, operations, and site locations. In conjunction with organizational structure development, a commercial-off-the-shelf (COTS) computer aided facilities management (CAFM) system was implemented to integrate data collection and user control. These facilities' management aspects include tracking building floor space usage, employee locations, AutoCad building designs, equipment inventory, operations and maintenance scheduling, etc. The systems engineering process included a spiral architecture development model, initial and recurring data validations, a risk management review, and multiple phases of tracking requirements and change control. Formal configuration management boards (CMB) were a critical element of development and continuing operation of CAFM. Use of an open systems interface design to allow exchange of data between CAFM and related databases from Human Resources and Security Departments was essential. By replacing the many separate legacy facilities programs with an integrated CAFM package, more complete data information was collected which allowed for better control and operation of facilities resources and improved strategic facilities' planning.
