Architecture

This page provides an entry-point into the statewide tier one enterprise architecture.

The over-arching principles document linked above identifies a set of principles developed by the Enterprise Architecture Committee and adopted by the Information Services Board; the purpose of these principles is to guide investments in technology and the evolution of the rest of the architecture.

Consistent with the NASCIO architecture framework, the Washington statewide tier one enterprise architecture is segmented into four sub-architectures that address particular views on the enterprise.

• Business Architecture is a high-level representation of the vision, mission, goals, objectives and business strategies that comprise the strategic business intent of Washington state government
• Information Architecture aligns business processes to information systems that support them
• Solution Architecture facilitates and describes the definition of architectural enterprise solutions (business, infrastructure, and application solutions)
• Technology Architecture is a disciplined approach for documenting the enterprise's current and emerging technologies in the form of policies, standards, and guidelines
• Reference Architectures define overall approaches to addressing particular technology decision-making areas

(The description of each sub-architecture above is adopted from the NASCIO Enterprise Architecture Tool-Kit, version 3.0.)
