The HHS Enterprise Architecture

The HHS Enterprise Architecture provides the foundation for allocating resources of all types toward the realization of the Department’s strategic business goals and objectives. The EA is a strategic resource that helps HHS plan, invest in, and implement information technology solutions to meet business needs and help manage the IT investment portfolio. It provides a mechanism for understanding and managing complexity and change. EA products identify the alignment of organizational business and management processes, data flows, and technology.  They also enable identification of capability gaps and duplication.  The role of the enterprise architecture within the broader cycle of strategic planning and execution was reflected in the initial “Architect” phase of the iterative performance improvement lifecycle described by OMB, as depicted in Figure 1.

This figure shows the OMB performance improvement lifecycle which includes the following phases: Strategize & Architect, Develop Programs, Formulate, and Execute. It also shows an integration point for all these activities and how the IT project life cycle starts in the Formulate phase and ends in the Execute phase.

HHS EA Program Vision

The HHS Enterprise Architecture is the catalyst for business and information technology transformation, bringing organization and clarity to HHS’s complex environment, and delivering stronger value to the American public for their health and human services investments.

HHS EA Program Mission

The diagram below depicts the layers of the HHS architecture. Each layer of the architecture contains information specific to that category, and is related to other information across the architecture. The HHS EA aligns with the FEA and links to information about the FEA are provided below.
 

HHS Framework: eight horizontal and two vertical layer described on this table



Strategy – identify the strategic goals and objectives for COOP and/or Pandemic

Business – determine what essential business activities are needed to achieve the goals and objectives and how they will be continued.

Investment – represents the financial aspect of an enterprise. It includes concepts that allow the EA information to be reconciled with investment and project control information.

Services/Systems – identify any needed systems that will provide the services needed to support the above business activities and how they will be made available

Data – determine what data will be needed to support the business activities, and where it can be obtained.

Services/Systems – identify any needed systems that will provide the services needed to support the above business activities and how they will be made available

Technology – identify the technology to be used in building the system services

Workforce – identify the roles and key positions needed to support the above business activities

Facilities – identify the facilities needed to support the business activities above.

Security and Privacy – identify the security controls that are to be in place at each layer and how they will be implemented

Performance – identify measurement indicators to measure performance at all levels of the enterprise






HHS EA Principles

The HHS Enterprise Architecture functions based on the following 9 principles.

  1. HHS is citizen-centered and business-driven, with services defined and delivered based on the needs of their consumers. (Customer Focused)
  2. HHS is performance-driven, measuring success in terms of mission execution and continuous improvement towards meeting HHS Strategic Goals and Objectives. (Performance)
  3. The HHS EA reflects a standards-based approach that promotes and facilitates technology standardization and reuse, interoperability, data sharing, and overall Departmental efficiency and effectiveness. (Standards)
  4. HHS develops and implements business services using a required, structured Enterprise Performance Life Cycle methodology. (EPLC)
  5. HHS manages information and data as enterprise assets, ensuring integrity, confidentiality, and availability, at all levels of the department. (Information Assets)
  6. HHS requires security and privacy practices to protect information assets from unauthorized use, disclosure, disruption, modification, or destruction. (Security/Privacy)
  7. HHS integrates the planning, management, and governance of all HHS OPDIV enterprise architectures into a unified EA that is aligned with the Federal Enterprise Architecture (FEA). (Federated Architecture)
  8. HHS streamlines business processes in alignment with Departmental and government-wide initiatives. (Efficiency)
  9. HHS evaluates investments against business requirements and service needs, with a philosophy of first Reuse, then Buy, then Build. (Reuse)
