context_section_description: The Treasury Enterprise Architecture Framework (TEAF) an architectural framework that supports Treasury's business processes in terms of products. This framework guides the development and redesign of the business processes for various bureaus in order to meet the requirements of recent legislation in a rapidly changing technology environment. The TEAF prescribes architectural views and delineates a set of notional products to portray these views. 
  The TEAF describes provides:
  Guidance to Treasury bureaus concerning the development and evolution of information systems architecture,
  A unifying concept, common principles, technologies, and standards for information systems, and
  A template for the development of the Enterprise Architecture.
  The TEAF's functional, information and organizational architecture views collectively model the organization’s processes, procedures, and business operations. By grounding the architecture in the business of the organization, the TEAF defines the core business procedures and enterprise processes. Through its explicit models, a TEAF-based architecture enables the identification and reasoning of enterprise- and system-level concerns and investment decisions.
