* Treasury Architecture Development Guidance, and
* the Treasury Architecture Development Process.<ref name="TEAF00"/>
In July 1997, the Treasury issued additional guidance to complement Treasury Information System Architecture Framework (TISAF).

The TEAF represents a revision to TISAF, based on 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. These work products align with FEAF models and with Department of Defense Architecture Framework ([[DoDAF]]) products.<ref name="TEAF00"/>
