Enterprise architecture is a structural expression of an enterprise from various perspectives, such as:
- Business: products and services
- Structure: organizational units and people
- Processes: value chains and information and material flow
- Technologies: infrastructure, systems, and data
As a result, enterprise architecture helps in 1) realizing an organization and its operations, 2) communicating needs and requirements, and 3) designing and developing systems.
An enterprise architecture framework provides principles and practices for creating and using the architecture description of an enterprise.
Zachman (1987), TOGAF (1995), and the Federal Enterprise Architecture Framework (1999) are well-known enterprise architecture frameworks.
