Enterprise Technical Architecture
Enterprise Design Patterns are developed by the Office of Technology Strategies (TS) in coordination with internal and external subject matter experts (SME) and stakeholders.
Enterprise Design Patterns take into consideration the current and future technology initiatives across TS. They also incorporate use cases in the commercial and government sector while specifying VA use cases to industry as well as internal/external stakeholders. The figure below illustrates these relationships.

Scope
Enterprise Design Patterns provide a standardized framework of capabilities and constraining principles to aid all Project Teams in the development, acquisition, and/or implementation of IT systems and services. Approved Enterprise Design Patterns are incorporated into Design, Engineering, & Architecture (DE&A) Compliance. Per VA policy (VA Directive 6551), all VA IT projects developed in accordance with OI&T integrated development and the Veteran-focused Integration Process (VIP) must evaluate Enterprise Design Patterns as they progress through the VIP lifecycle.
Usage
Enterprise Design Patterns are:- Limited enough to be usable and broad enough to be reusable
- Formalized, validated best practices that projects will leverage in the establishment of their solution architecture
- Enterprise-level guidance that guides projects to the appropriate implementation resources to establish design specifications for system development and integration
- Project-specific solution architectures
- Implementation policy or directives
- Software development kits
- Set of approved tools and technologies (this is covered by the Technical Reference Model)
- Privacy & Security
- Enterprise Architecture
- Interoperability & Data Sharing
- IT Service Management (ITSM)
- Mobility
- Cloud Computing
Enterprise Design Patterns are also posted to the Office of Technology Strategies website page in the MAX Federal Community Department of Veterans Affairs-External space at http://www.max.gov/
