Enterprise architecture applies architectural discipline to the end-to-end enterprise, treating the enterprise as a system. To assist SOA disciplines within the organization, enterprise architecture provides the following tools and techniques:
- Defined structured traceable representation of business and technology that link IT to the business
- Defined principles, constraints, frameworks, patterns, and standards which form the basis for design governance, ensuring aligned services, interoperability, and re-use
- Links different perspectives to a single business problem and establishing a consistent model to address various problem domains and test of completeness
- Provides consistent abstractions of strategies and project deliverables to allow bottom-up and top-down outputs to be compiled into a shared repository for planning and analysis
