The SAP Enterprise Architecture Framework (EAF) is a methodology and toolset primarily to support the effective adoption of SOA. It is based on The Open Group Architecture Framework (TOGAF) and specifically designed to support packaged solutions and Service-oriented architecture (SOA).
The TOGAF Architecture Development Method is a generic method for architecture development, which is designed to deal with most system and organizational requirements. However, it will often be necessary to modify or extend the Architecture Development Method (ADM), to suit specific needs.
SAP EAF is a complementary set of additions to TOGAF to support the specific characteristics of package and service-based architectures. SAP EAF was developed during 2007 by a team of SAP and Capgemini Enterprise Architects, most of whom were TOGAF 8.1 accredited practitioners. SAP EAF was formally launched at the SAP SAPPHIRE user conference in Atlanta, USA during 2007.
