EA is the process of translating business vision and strategy into effective organizational change by creating, communicating and improving the key requirements, principles and models that describe the organization’s future state and enable its evolution. Gartner Copyright Kemsley Design Ltd., 2011 6 What Is EA? 1. A formal description of a system, or a detailed plan of the system at a component level to guide its implementation – OR – 2. The structure of components, their inter- relationships, and the principles and guidelines governing their design and evolution over time TOGAF Copyright Kemsley Design Ltd., 2011 7 What Is EA? An architectural discipline that merges strategic business and IT objectives with opportunities for change and governs the resulting change initiatives IBM Copyright Kemsley Design Ltd., 2011 8 EA Defined l Strategy (evolutionary path) to achieve desired business future state l Artefacts for documenting and communicating strategy l Many methodologies/frameworks: may be a process, a taxonomy or a practice Copyright Kemsley Design Ltd., 2011 9 EA Goals l Enterprise planning l Describe current and future state of the structure of an enterprise l Business-IT alignment l Links between business/technology artefacts l Business visibility and measurement l Change-friendly capability delivery l Adaptable and agile for continuous change Copyright Kemsley Design Ltd., 2011 10 What is BPM? BPM is a management discipline that treats processes as assets that directly contribute to enterprise performance by driving operational excellence and business process agility.
