Enterprise architecture (EA) is the process of translating business vision and strategy into effective enterprise change by creating, communicating and improving the key requirements, principles and models that describe the enterprise's future state and enable its evolution.
Enterprise architecture makes a vital contribution to the running of a large organisation. It was originally developed in order to manage a rapid growth in the cost and complexity of IT systems, using knowledge gained from software structure and design.
For this reason, enterprise architecture is often thought of as a component of IT governance. However, the discipline has evolved and extended this original scope.
Enterprise architecture is now about structuring business capabilities and processes in order to support your long-term business strategy. Effective application of enterprise architecture will enable you to improve your productivity and performance.
