“Business areas” separate government operations into high-level categories relating to the purpose of government, the mechanisms the government uses to achieve its purposes, the support functions necessary to conduct government operations, and resource management functions that support all areas of the government’s business. “Business areas” are subdivided into “areas of operation” or “lines of business.” The recommended information types provided in NIST SP 800-60 are established from the “business areas” and “lines of business” from OMB’s Business Reference Model (BRM) section of Federal Enterprise Architecture (FEA) Consolidated Reference Model Document Version 2.3
