EA (Enterprise Architecture)

Enterprise Architecture - abbreviated as EA.

EA is the term that refers to the formal description of the organization architecture and its key elements. The EA is often used in informatics (in business information systems). EA represents a complex description of the organization in all its contexts and perspectives (dimensions), like the zoning plan describes the city. Enterprise Architecture describes all key dimensions of the organization:

• Business objectives
• Business functions
• Business processes
• Organizational structure
• Data and information
• Software (business applications)
• Hardware (IT infrastructure)
• Placement (location within the organization )

In the terms of decomposition of the organization can be, more or less related, considered following approaches:

• Organizational architecture
• Basic systems of the organization
• Basic parts of the organization (Mintzberg)
• Organizational components

Basic frameworks for Enterprise Architecture:

• CIMOSA
• TOGAF
• DODAF
• FEA/FEAF
• 8 Omega Framework
• PEAF (Pragmatic EA)
• Zachman Framework
