Treasury Information System Architecture Framework

This guidance, which was finalized in September 1997, provides "how to" processes for developing an information systems architecture in accordance with TISAF.

[4] In 1989 US congress granted $200,000 for the department-wide implementation of the Treasury Information System Architecture Framework.

[6] It was the result of an evaluation of Department and bureau experiences in applying and using the TISAF, and emerging best practices from other government organizations and industry.

TEAF is intended to emphasize the broader scope of the architecture framework, which includes both business and technical vantage points within an enterprise-wide perspective.

The TEAF includes descriptions of a common suite of work products for documenting and modeling EAs.

The logical architecture (e.g., business functions and information flows) is defined first and then used to specify supporting systems (e.g., interfaces, standards, and protocols).
