 (EAP), which he defines as “the process of defining architectures for the use of information in support of the business and the plan for implementing those architectures”. Spewak’s approach to EAP is similar to that taken by DOE in that the business mission is the primary driver. That is followed by the data required to satisfy the mission, followed by the applications that are built using that data, and finally by the technology to implement the applications. This hierarchy of activity is represented in the figure on the right, in which the layers are implemented in order, from top to bottom.

Based on the Business Systems Planning (BSP) approach developed by John Zachman

, EAP takes a business-oriented approach to architecture planning to provide data quality, access to data, adaptability to changing requirements, data interoperability and sharing, and cost containment. The ultimate goal of an Enterprise Architecture is to define practical and implementable application and technology projects along with those projects required to prepare the organization for its future IT environment. This view counters the more traditional view that applications should be defined before data needs are determined or provided for.

His approach to Federal Enterprise Architecture has helped organizations with modeling, business strategy planning, process improvement, data warehousing, and various support systems designs, data administration standards, object-oriented and information engineering methodologies, and project management. The Enterprise Architecture Planning (EAP) methodology is beneficial to understanding the further definition of the Federal Enterprise Architecture

Dr.Spewak was a founding Partner of Enterprise Architects, Inc. Along with his two partners, Frank Digaetano and Stephan DeVocht, Steve taught several generations of Enterprise Architects and performed many consulting assignments for Fortune 500 clients, US and Canadian Federal Government organizations, as well as State, Local and Tribal government bodies. Since the publication of his seminal book, he and his partners introduced enhancements to the EAP methodology such as updates for technology architecture, expansion of implementation requirements, and methods for calculating planning project duration and effort. They also developed a planning tool (EAP Toolset Templates, and the StratTac Group LLC Planning Templates, to assist organizations EAP efforts.
