From stove-piped projects to unified enterprise architecture

Strategic considerations for e-authentication service development

In the last decade, many large organizations have developed numerous information systems but often times with very little coordination. As a result, information systems can be redundant and cannot interoperate, and data is repetitive and inconsistent (stove-piped information systems). In fact, one of the greatest challenges facing large organizations, such as the US federal government, is the failure of information systems to interoperate and effectively share business-critical data. Although it isn't easy, you can establish a unified enterprise architecture (EA), align projects with that enterprise architecture, and carefully plan and control your investments. I first discuss the enterprise architecture approach to an e-authentication project and then concentrate on some technical considerations.
