A Synergistic Assessment of the Federal Enterprise Architecture Framework against GERAM (ISO15704:2000)

Abstract

The federal enterprise architecture framework (FEAF) is perhaps the most adopted EA framework, especially within the U.S. Government agencies. Either the FEAF has been adopted as-is or other frameworks derived from the FEAF have been used. The FEAF today continues to be the most comprehensive framework available for guidance by agencies. It consists of a full-fledged methodology, several reference models, target architectures, and even a toolkit that facilitates adoption across all agencies. This chapter evaluates the synergies between the comprehensive FEAF against the generalized enterprise reference architecture and methodology (GERAM) framework. The intent of the evaluation is to present the level of completeness in the FEAF based on GERAM requirements and additionally discuss areas where the FEAF goes well beyond ISO15704:2000 requirements leading to improvement opportunities in GERAM.
