Highlights
GAO reviewed the Federal Aviation Administration's (FAA) Display Channel Complex Rehost (DCCR) project, intended as an interim replacementof the Display Channel Complex (DCC), focusing on: (1) recent outages caused by DCC; (2) whether DCC was meeting its system availability requirement; (3) FAA's projections of future DCC outages and availability; and (4) whether FAA was effectively managing the DCCR acquisition to ensure delivery of specified capabilities on schedule and within estimated cost.
Recommendations
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| Department of Transportation | To maximize the likelihood of delivering promised DCCR capabilities on time and within contract budgets, the Secretary of Transportation should direct the FAA Administrator to ensure that (1) contention for human test resources during DCCR concurrent test activities, and (2) change control over system test configuration baselines during concurrent test activities, are managed as formal program risks. At a minimum, this formal risk management should include definition, implementation, and tracking of risk mitigation strategies. |
Closed – Implemented
FAA added contention for human test resources during concurrent test activities, and changed control over system test configuration baselines during concurrent test activities to its formal DCCR risk watch list. GAO confirmed that the risks are now being formally managed.
