2006 Awards: Enterprise Architecture

District of Columbia
District Enterprise Integration Stack

The District Office of the Chief Technology Officer (OCTO) has devised a strategy that integrates multi-agency data, while preserving legacy data investments. OCTO dubs its strategy the District Enterprise Integration Stack (DEIS). The DEIS uses enterprise application integration (EAI) tools to pass data from legacy applications up through an enterprise service bus to multi-agency applications and a citywide portal framework.

This new data and application integration model incorporates an array of enterprise application tools, data warehouses, portal frameworks and web services. DEIS consists of four layers with cumulative functionality.

While web browsers take data and make it accessible to consumers, EAI takes data from one set of servers and makes it accessible to applications on other servers. OCTO's objective was to give the district's highly decentralized IT environment a common communication highway through EAI. “The District Enterprise Integration Stack (DEIS) is a critical part of the district's commitment to modernize the way we govern and interact with our citizens. Our DEIS strategy and implementation exemplifies sophisticated cross agency data and application integration. Our first two service modernization programs, human and administrative services, are providing instrumental enhancements and savings each year. I project superior results when the other seven programs are operational.”
Suzanne J. Peck, Chief Technology Officer, District of Columbia

For example, the call center uses a custom EAI adapter to connect its software to the customer service broker. That broker, in turn, translates these requests electronically into a format that is understood by the Department of Public Works' (DPW) fulfillment system.

And the public sees the benefits. A broken streetlight is fixed. A pothole is filled.

DEIS Level One defines stovepiped legacy application data from 66 District agencies. Level Two allows district agencies to tap into this district-wide legacy data and communicate with each other. Level Three permits interagency collaboration to solve critical problems in areas such as public safety and human services. Level Four invites the public in, offering a common data look and feel so that citizens—and the district employees who serve them—can easily navigate district government services.

While several years from fully achieving this vision, the district is already reaping extraordinary rewards from the DEIS architecture. District-wide adoption rates for integrated applications are up, operational costs are down and agency resistance to change is dissolving. Perhaps most significantly, residents now frequently comment on the ease of completing transactions with their government. Resident Don Marlais recounted his experience requesting bulk trash pick up service online:

"The entire process took about three minutes. At the end, I was given a confirmation number and date…the articles were picked-up as advertised."
