II. Purpose The main purpose of TOGAF is to serve as a complimentary EA method rather than compete with other frameworks. It enables an organization to design, evaluate and build the right architecture instead of one for all approach. It can be tailored to meet 11/17/2017
a specific business needs. This particular feature is what makes the TOGAF different from other frameworks. III. Scope The scope of the TOGAF depends on different considerations and usually includes business processes, strategic direction, mission, and IT components. In general, the framework identify the core and soft enterprise units before deciding the scope of the EA. The core enterprise units are those that are affected the most by EA and stand to gain the most from it. The soft enterprise units are those that will see certain changes in their capacity while working with the core units but not directly affected by the EA. TOGAF also consider extended units which are functions outside the organization EA scope but who work with the organization’s EA on some form. Stakeholders and governance are some of the consideration TOGAF makes before the EA is adapted. IV. Principles TOGAF principles are guidance an organization use through set of values, actions and results. The framework approach principles from three directions. The first approach is the enterprise principle. This approach deal with decision making throughout the organization’s enterprise architecture and set a proper guideline on how the organization’s mission objective can be achieved. It serves as an important component of the IT Governance strategy. The second approach is the architectural principles which deal with how IT resources and assets are used across the enterprise. The main purpose of the architectural principles is to insure the efficient and productive use of the organization’s IT infrastructure. The third principle approach is the Architecture which is the subset of the IT principle approach. It deals with the architectural processes including the planning, implementation and maintenance of the EA. TOGAF dictate that each principle approach directly aligns with the organization’s business objectives and key architectural drivers.
