NIEM Governance

NIEM is governed by a number of groups and committees that support its development, day-to-day operations, and future evolution. Click on the options below to explore NIEM’s governance structure.

NIEM Governance Structure

  • The NIEM Executive Steering Council (ESC) is the decision-making body regarding membership, funding requirements, program or technical direction, committee, and Program Management Office (PMO) personnel appointments
  • The NIEM Program Management Office (PMO) executes the vision of NIEM established by the Executive Steering Council (ESC), while managing the day-to-day operations of NIEM. The office encourages the adoption and use of NIEM and oversees all working group and committee activities
  • The NIEM Technical Architecture Committee (NTAC) defines and supports the technical architecture that governs NIEM; it documents, implements, and maintains NIEM’s technical specifications
  • The NIEM Business Architecture Committee (NBAC) sets the business architecture and requirements of NIEM, manages the NIEM Core data model, and facilitates the processes for the regulation and support of NIEM domains
  • NIEM Domains are created through a formal charter, agreed between the PMO and the domain steward, which includes organizational and dispute resolution frameworks. The domain co-chairs are the members of the NBAC.
  • The NIEM data model and technical specifications are created and adopted by the domains, the NBAC, and the NTAC. These are the governance bodies that must possess the attributes of openness, balance of interest, due process, an appeals process, and consensus.

NIEM Executive Steering Council (ESC)

The ESC serves as NIEM’s decision-making body regarding membership, funding requirements, program or technical direction, personnel appointments, and other organizational decisions as required for supporting NIEM management.

The primary sponsors of NIEM are Chief Information Officers (CIOs) of the U.S. Department of Defense (DOD), U.S. Department of Homeland Security (DHS), U.S. Department of Justice (DOJ), and U.S. Health and Human Services (HHS), and as such, are members of the ESC. Advisory members and invited guests of the ESC include but are not limited to the following.

  • The Global Justice Information Sharing Initiative (Global)
  • The National Association of State Chief Information Officers (NASCIO)
  • The Executive Office of the President Office of Management and Budget (OMB) Federal Enterprise Architecture (FEA) through the Chief Architect
  • The Office of the Director of National Intelligence (ODNI) through the Program Manager of the Information Sharing Environment (PM-ISE).
  • The Chief Information Officer of CrimTrac, Government of Australia

NIEM Management Office (NMO)

The NMO executes the ESC’s vision for NIEM while managing day-to-day operations, encouraging adoption and use of NIEM, and overseeing all working group and committee activities. The NIEM NMO coordinates with Communities of Interest (COIs), principal stakeholders, and other information-sharing initiatives to promote collaboration and interest in NIEM priorities.

NIEM Business Architecture Committee (NBAC)


As specified in its Charter, the mission of the NBAC is to set the business architecture​ and requirements of NIEM, manage NIEM Core, and facilitate the processes for the regulation and support of NIEM domains. The NBAC focuses on the following areas:

  • Business Architecture: The NBAC oversees and validates the construction, maintenance, and use of the business architecture framework for NIEM.
  • NIEM Core: The NBAC provides management and oversight of the NIEM Core—the central part of the NIEM data model that’s commonly understood across all domains.
  • Community: The NBAC serves as the forum for the admission of new domains and interactions between domains, and coordinates action to maintain the NIEM community.

Roles and responsibilities

The committee’s responsibilities are to:

  • Maintain the integrity, usability, and maturity of NIEM core, and engage in any requisite harmonization and issue resolution activities.
  • Determine the need for new data model releases as necessary, such as to accommodate new domains and content, or to provide business requirements to the NTAC.
  • Submit recommendations to the ESC concerning the admission of a new domain into the NIEM data model.


The NBAC is made up of stakeholders across diverse communities. NIEM’s domains—communities that are formally established to manage and govern a portion of the NIEM data model—serve as the foundations of the committee. The NBAC is led by co-chairs and includes voting members, a NIEM PMO liaison, and observers and invited participants.

Ongoing activities

NBAC members continuously gather and assess community business requirements for architecture enhancements. Also, with the support of lead developers, NBAC members conduct ongoing cross-domain and core data harmonization as well as issue resolution activities.

Annually, the NBAC co-chairs conduct a review of the committee's membership, activities, and domain maturity.

Fiscal Year Activities

NBAC Stands Up the Emerging Technologies Tiger Team The NBAC Emerging Technologies Tiger Team (E3T) has worked collaboratively to focus on the impact of artificial intelligence, internet of things (IoT),  and identity management on the NIEM community; NIEM’s role and opportunities with Open Data; and alignment of NIEM vocabularies and Domain support with international standards. All NBAC members are invited to participate.
