An enterprise architecture (EA) is a conceptual blueprint that defines the appropriate structure and operating model. The EA links the organization’s mission, strategy, and operating (business) activities, to the Information Technology (IT) strategy, using multiple architectural models that present how the current and future strategic needs will be met in an efficient, sustainable, agile, and flexible manner.
The EA is a key structured approach and methodology for CIOs to support continual alignment and management of the organizational business and IT assets. Though, many corporate and public-sector CIOs are successful others experience difficulties in developing and implementing an EA.
EA is a challenging discipline and meticulous attention to the development can mean the difference between failure and success. The objective is not to create a flawless or elegant architecture for the short term, but the most adaptable and compliant architecture for the long-term.
A successful EA will generally result in the below benefits:
- Confirmation and reapproval of business and IT strategic intent
- Map of future (To-be) state with alignment of the business and IT strategy
- Identification of the change initiatives necessary to attain planned future (To-be) state
- Project Plan to steer the implementation of EA associated change initiatives
- Method to quickly identify alignment ‘Gaps’ between business and IT strategy
