An enterprise architecture framework based on a common information technology domain (EAFIT) for improving interoperability among heterogeneous information systems

Recent developments in information systems (ISs) have resulted in a critical need for integration and retention of heterogeneous ISs in various domains, using their commonalities. Stovepipe systems have been developed because of inconsistencies in planning architecture among stakeholders. Several countries are currently adopting enterprise architecture (EA) systems, such as Zachman AF (ZF), C4ISR AF, SBA, and FEAF, in order to solve various IS problems in the field of information technology, but enterprise architecture framework (EAF) legacy systems can be inadequate to solve problems arising from stovepipe systems. An EAF is required to satisfy aspects of both EA and system architecture (SA) inside a common information technology (IT) domain. This paper proposes a new enterprise architecture framework that will resolve the problems inherent in previous frameworks and their features.
