Enterprise Solutions Architecture (ESA)
(Context: Enterprise Architecture)
The expectations of government to deliver more services, to deliver them better and more cheaply presents a challenge for the Commonwealth. Well-engineered automated solutions1 can increase productivity in service delivery to help meet these expectations.
Commonwealth agencies make significant investments in these automated solutions in order to carry out the business of Virginia government.2 The Commonwealth Enterprise Solutions Architecture (ESA) provides the framework/model and methodology that supports the transition from silo-based, application-centric and agency-centric information technology investments to an enterprise approach where solutions are designed to be flexible. This allows agencies to take advantage of shared and reusable components, facilitates the sharing and reuse of data where appropriate and makes the best use of the technology infrastructure that is available.
The ESA needs to contain a unified view of solutions to achieve this increase in reuse and the reduction of solution complexity. To support this, the framework/model and methodology includes: inventories, governance/guidance and the relationships between agency applications and the other EA component architectures.
