ExtendedEnterpriseArchitectureMaturityModel(E2AMM)SMv2.pdf

IFEAD is an independent research and information exchange organization working on the future state of Enterprise Architecture.

The IFEAD Extended Enterprise Architecture Maturity Model (E2AMM)sm provides a path for enterprise architecture and procedural improvements within an organization. As the enterprise architecture matures, predictability, process controls and effectiveness also increase. Development of the enterprise architecture is critical because it provides the rules and definition necessary for the integration of information and services at the operation level across organizational boundaries. Enterprise architecture includes business tasks and activities and representations, and supportive technology components. At its fullest maturity, enterprise architecture becomes an extended-enterprise concept and prescribes the infrastructure for extendedenterprise businesses and provides the conditions and structures for allowing information to flow from organization to organization, just as radio waves flows through the radio and electricity flows through the wiring of a building.
