Enterprise Architecture (EA) Policies, Standards, and Guidelines

  • Enterprise Architecture Policy - EA200 (February 2018)

    Establishes the Commonwealth's EA as the primary source for providing information technology (IT) direction and technical requirements, which govern the acquisition, use, and management of IT resources by executive branch agencies. This document contains Commonwealth policy statements related to applications systems development and open source software. It provides the process used to govern agency requests for changes and exceptions to the commonwealth's EA requirements. And this policy ensures all recommendations and requests for changes or exceptions are logged, reviewed and considered in a timely manner.

  • Enterprise Architecture Standard - EA225 (January 2021)

    Establishes direction and technical requirements governing the acquisition, use and management of IT resources by executive branch agencies. The intent of this document is to provide a single consolidated list of requirements related to the Commonwealth's EA for use by executive branch agencies and their business partners. Architecture direction for agencies when planning, changing or adding to their information technology is presented in two forms:

    1. Requirements: Statements providing mandatory EA direction.
    2. Technology component standard tables: Tables indicating what technologies or products agencies may acquire at a particular point in time. The requirements are mandatory when acquiring a new or replacing an existing technology or product.

Enterprise Architecture Technology Roadmaps

The Enterprise Technical Architecture (ETA) consists of multiple technical domains and topics providing direction, recommendations, and requirements for supporting solutions architecture and implementing a successful ETA. Technology roadmaps are a crucial part of the Commonwealth's ETA, and assist with guiding development and support of information systems and technology infrastructure.

The intent for governance of technology versions is simply to prevent last minute version updates and their consequent negative impact on delivering quality information technology that supports our Commonwealth business architecture. In fact, updating to current versions should be a recurring task for agencies and suppliers of Commonwealth information technology services, because this will result in increased staff productivity, maintaining reliable security, and reducing the costs of legacy maintenance. 

The following roadmaps enable agencies and suppliers to plan more predictable and scheduled updates.  Because assessments are "forecasted" with best available information at the time of a decision, they are subject to change to maintain resilience with changes occurring outside the Commonwealth's control. VITA's robust exceptions process is readily available to account for any unforeseen conflicts that may arise following guidance found in the technology roadmaps. Please use the Archer application to enter an EA exception.

Following are the most current roadmaps available.

Enterprise Solutions Architecture (ESA)

To extract applicable ESA information to support your agency's business needs, please log in to our VITA Archer application to run an extensive array of reports.


The RSA Archer GRC platform consists of agency inventories of applications, data assets and software tools. Archer creates a common set of capabilities, methods, and taxonomy for risk and compliance programs.  This enables greater integration of data, while creating a common language and reporting structure to share results.


Enterprise Technical Architecture (ETA)

The enterprise technical architecture (ETA) consists of eight technical domains and includes related topic reports that provide direction, recommendations, and requirements for implementing ETA principles, requirements and recommended practices. The ETA guides the development and support of an organization's information systems and technology investments.
