What's New

VA Enterprise Architecture (VA EA) Third Quarter 2021 Release

The Office of Information and Technology (OIT), Architecture and Engineering Service (AES) published its VA Enterprise Architecture (VA EA) Third Quarter FY21 Release on July 16, 2021

This Third Quarter Release update includes the following:

For complete details and additional information, visit the highlights listed below:

Product Line Architecture (PLA)

Product Line Architecture (PLA) is an operating construct that aligns IT resources and funding to the enterprise’s most critical business capabilities. PLAs describe the current state, target state, and transition plans by Product Line.

The PLA page contains information about the initial steps needed to migrate to a Product Line Management (PLM) framework in a Development Security Operations (DevSecOps) environment.

Product Line Artifacts - Updated

The VA Architecture Framework (VAAF) defines a way of representing VA Enterprise Architecture that enables stakeholders to focus on specific areas of interest in the Enterprise, while retaining sight of the big picture. To assist decision-makers, VAAF provides the means of abstracting essential information from the underlying complexity and presenting it in a way that maintains coherence and consistency. One of the principal objectives is to present this information in a way that is understandable to the many stakeholder communities involved in developing, delivering, and sustaining capabilities in support of the stakeholder’s mission. It does so by dividing the problem space into manageable pieces, according to the stakeholder’s viewpoint. With the addition of the following two views, there are now seven core architecture views identified for each Product Line:

  • SV-3: The System-System Matrix provides a tabular summary of the system interactions specified in the SV-1 Systems Interface Description model for the Architectural Description. The matrix format supports a rapid assessment of potential commonalities and redundancies.
  • SV-8: System Evolution depicts the evolution of each system in the Product Line over a six-year period.

For more information, visit the Product Line Architecture (PLA) page.

Business Architecture

The Business Domain describes VA’s capabilities, business functions, IT process requests, end-to-end processes, business processes, organizations, laws, regulations, policies, and directives that are exercised to accomplish the Agency’s mission. Most of this domain’s elements are enabled by data, information, systems, and technologies from the other VA EA domains. The models and reports in this domain, when combined with information from other domains, can provide new insights into gaps, redundancies, integration risks and opportunities, and process and technology improvements. You may also find information about VA business content, including interactive versions of many of the below models and reports, within the VA Enterprise Architecture Repository (VEAR).

The following models and reports were published this quarter:

The Data Subject Area Models Information Class to VA BRM Report illustrates how the Data Governance Council (DGC) subject area data entities (information classes) are related to specific VA BRM Functions and Business Functions and provides the necessary business context related to a DGC subject area data entity (information class) to:

        • Support the discovery of relevant data standards.
        • Enable improved functional integration.
        • Support decision-makers in making required trade-off and investment analysis in support of VA requirements for enterprise data sharing and data management.
        • Identify systems that may contain relevant data (i.e., all systems with a given business function could/should contain similar information classes) to support ADS migration planning.
      • VA BRM to OIT Process Asset Library (PAL) Mapping Report - Updated

The VA BRM to OIT Process Asset Library (PAL) Mapping Report illustrates the relationship between VA BRM elements (Capabilities, Service Lines, and Business Functions) and VA Business Processes maintained in the PAL. It establishes the traceability between VA BRM business functions and associated VA enterprise business processes, and enables the identification of gaps, redundancy and opportunities for improving the efficiency and effectiveness of VA enterprise business processes.

      • VA Business Reference Model (BRM) Category 2 Capability Views

2.6 Provide Information and Technology Services - Updated
The 17 VA Business Reference Model (VA BRM) Category 2 Capability Views below provide user-friendly, printable PDF versions of back/staff office Capabilities, Service Lines and Business Functions of the VA BRM.

For additional reports, models and products, please visit the Business Domain – Models, Reports and Visualizations page.
