The key role of this stage is to identify appropriate ISs [13][19]. EAP is an implementation plan [9]. In EA migration plan also known as transition plan EAP provides the process of using architectures for the is the essential strategy that will be employed for Transition utilizing ISs in order to support business and the plan in from the As-Is to the To-Be one.

The key role of this stage is order to implement architectures. It comprises the following using the proper implementation method [13][19]. It covers all aspects of the EA lifecycle- the planning for - Enterprise survey; enterprise understanding projects, the analysis of business - Current systems and technology architecture; requirements, the design of systems, the evolution of - Data architecture; systems, and the ongoing enhancements of all of the above.

It allows paths and pieces of content to be selected and extracted for - Implementation plan; application on specific projects [9][13]. Today's In , EAP has been changed and some items were there are several EA methods which they are introduced to added into the prior model. The intent of this change was to provide a plan for developing tailored ISs. The reason for structure of enterprise by ISs integrity [20]. EA adding governance into the new edition of EAP model was: implementing method can be independent or dependent to a through effective governance possible to become a real framework.

While EA framework tries to capture portfolio of approved transition plan projects. This refreshment helps to them, EA method tries to utilize models for developing strengthen and reconnect EAP to the continually evolving appropriate ISs and IT Infrastructure for enterprise [11][19]. EAP contains activities and processes transitioning, developing architecture contents, and in order to achieve To-Be architecture by considering four governing the comprehension of architectures.

Mentioned EA architectures including: Business, Data, Application, activities are fulfilled by employing an iterative cycle of and Infrastructure. It is also known as the Wedding Cake. It continuous architecture description and comprehension that covers two fist perspective of ZF [9]. The ZF prepares the broad description development. The ADM phases to trace designing and deciding on architecture ADM are [7]: suggests documenting of design rationale [7].

In contrast to more abstract methodology like business and IT views. Business Architecture Gartner, and TOGAF which were designed to solve general issue with EA development across a wide array of depicts the current architecture of business and enterprises, DODAF was designed to solve a wide array of analyzes gaps between it and desired one.

The DODAF method is Model-driven, that is specific Technology Architecture is employed to build up templates of data that are used to aggregate and the basis implementation.

It comprises eight sub- communicate data on a specific architectural issue. Opportunities and - Capability; Solutions comprises of assessment and choice of - Data and Information; implementing options. Migration Planning - Operational; concerns on prioritizing implementing projects in - Project; - Services; accordance with their dependencies.

Architecture Change supporting decision makers guide the development of EA Management concerns on future changes by using within the DOD whether the effort is on a strategic or repeated surveillance process in business and IT tactical level.

Gartner - Requirements Management provides the place Gartner methodology believes that EA is about bringing together three constituents: business owners, information for identifying and keeping requirements for other specialists, and the technology implementers. Bringing ADM Cycle phases.

TRM model base on success could be measured by pragmatic term [3]. Application, Application Platform and Communication Infrastructure and their interconnectivity depicts a system.

According to Gartner point of view EA project must be Moreover, it describes quality of services that organized by started with understanding enterprise direction on business, the system and the Standard Information Base in the EC not with finding its current position.

This activity needs to provides integrated information, management and ISs listen to the enterprise strategic plan and understanding how standards for architecture development [7]. The documentary did not introduce any ideas that were subsequently evidence cited strongly suggests that the Zachman adopted by the early or modern concepts of EA. For Framework, even if referred to, as in the cases of EAP instance, the organization of architecture according to and FEAF, did not significantly influence any EA different perspectives planner, owner, designer, builder, frameworks and methodologies in any real sense.

The and subcontractor and interrogatives what, how, and actual role of the Zachman Framework as the source of where recommended by the Zachman Framework was the basic concepts of EA seems to be overstated in the not adopted by the most prominent early and modern EA conventional wisdom.
