Highlights

In response to a congressional request, GAO assessed a Federal Computer Performance Evaluation and Simulation Center (FEDSIM) study to determine if it provided the Immigration and Naturalization Service (INS) with a basis for determining which computer system architecture best satisfied its current and projected information processing needs.

Recommendations

Recommendations for Executive Action

Agency Affected Recommendation Status
Department of Justice The Attorney General should, in approving INS plans, ensure that such plans include steps to: (1) analyze all pertinent work-load and cost data, including data acquired since the FEDSIM study, for the various INS mission-oriented systems, particularly for the seven casework and lookout systems; and (2) use the resulting analyses to evaluate alternative architectures, including those considered in the study.
Closed – Implemented
The recommendation was based on the fact that work load and cost data used in the FEDSIM study were too "soft" to justify implementing the architecture proposed by FEDSIM. In response, INS has deferred indefinitely any action to implement the study's proposal.
