According to Forrester Research, solution architecture is one of the key components by which Enterprise Architecture delivers value to the organization. It entails artifacts such as a solution business context, a solution vision and requirements, solution options (e.g. through RFIs, RFPs or prototype development) and an agreed optimal solution with build and implementation plans ("road-map").
Enterprise architects are at the top level of the architect hierarchy, meaning they have more responsibilities than solutions architects. While solutions architects focus on their own relevant solutions, enterprise architects focus on solutions for and the impact on the whole organization.
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
The Architecture Continuum specifies the structuring of reusable architecture assets and includes rules, representations, and relationships of the information systems available to the enterprise. The Solutions Continuum describes the implementation of the Architecture Continuum by defining reusable Solution Building Blocks (SBBs).
The British Computer Society's "Reference Model for Enterprise and Solution Architecture" also follows this subdivision but additionally mentions the (single) application architecture level just below the applications architecture as well as the domains of information architecture, information systems architecture, or security architecture (a ...
The Java Platform, Enterprise Edition architecture is a layered reference architecture which provides a template solution for many enterprise systems developed in Java. Examples of implementing frameworks include Glassfish and Wildfly. The IBM Insurance Application Architecture [3] is a reference architecture for the Insurance domain.
In the US Federal Enterprise Architecture enterprise, segment, and solution architecture provide different business perspectives by varying the level of detail and addressing related but distinct concerns. Just as enterprises are themselves hierarchically organized, so are the different views provided by each type of architecture.
Enterprise architecture management (EAM) is a "management practice that establishes, maintains and uses a coherent set of guidelines, architecture principles and governance regimes that provide direction and practical help in the design and development of an enterprise's architecture to achieve its vision and strategy."
