The federal government has a huge set of responsibilities, limited resources and business processes that have evolved over decades. Work on the government’s enterprise architecture has shown that many of those processes are obsolete, and the government needs to move toward a new and significantly different business architecture.
Given the size of the government, the process could take a while — and that is a problem.
We might be able to wait years for a complete migration, but we need to begin seeing benefits now. The service-oriented architecture (SOA) approach offers results in the near term while moving government toward the longer-term goal.
