Enterprise Architecture (EA)

Discipline that describes and governs an organization's business, data, application and technology structures to achieve strategy.

Definition

Enterprise architecture provides baseline and target descriptions, roadmaps and governance to guide change across the enterprise. Frameworks such as TOGAF, Zachman and FEAF structure the practice, and ArchiMate provides a modeling notation.

Exam tip

TOGAF defines four architecture domains: business, data, application and technology.
