GAO reviewed the Federal Aviation Administration's (FAA) air traffic control (ATC) modernization effort, focusing on: (1) whether FAA has a target architecture and associated subarchitectures, to guide the development and evolution of its ATC systems; and (2) what, if any, architectural incompatibilities exist among ATC systems and the effect of these incompatibilities.
Recommendations for Executive Action
|Department of Transportation||1. The Secretary of Transportation should direct the Administrator, FAA, to ensure that a complete ATC systems architecture is developed and enforced expeditiously and before deciding on the architectural characteristics for replacing the Host Computer System.|
|Department of Transportation||2. The Secretary of Transportation should direct the Administrator, FAA, to establish an effective management structure for developing, maintaining, enforcing the complete ATC systems architecture. Specifically, the Administrator should: (1) assign the responsibility and accountability needed to develop, maintain, and enforce a constrained ATC systems architecture to a single FAA organizational entity; (2) provide this single entity with the resources, expertise, and budgetary and organizational authority to fulfill its architectural responsibilities, and (3) direct this single entity to ensure that every ATC project conforms to the architecture unless careful, thorough, and documented analysis supports an exception.|
|Department of Transportation||3. Given the importance and the magnitude of the information technology initiative at FAA, GAO recommends that a management structure similar to the department-level CIOs as prescribed in the Clinger-Cohen Act be established for FAA.|
