TOGAF is an open framework, providing a practical, definitive and proven step-by-step method for developing and maintaining enterprise architecture. Common architecture viewpoints. principles at the enterprise level. protected against unauthorized or accidental modifications, fraud, IP; this must be capable of both avoiding compromises and reducing liabilities, Resources on such policies can be found at the SANS Institute (refer to, This is one of three closely-related principles regarding data: data is an asset; data is shared; and data is architecture might be supported for specific cases if there is a consensus As deliverables are typically the contractual or formal work products of an architecture project, it is likely that these deliverables will be constrained or altered by any overarching project or process management for the enterprise (such as CMMI, PRINCE2, PMBOK, or MSP). The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture today that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. that data in the shared environment can continue to be used by the new applications, For both the short term and the long term we must adopt common methods and tools for creating, maintaining, and so as to ensure alignment of the architecture and implementation of the Target Architecture with business strategies and 3.20 Architecture Viewpoints. administration" job titles and forums with charters implying responsibility, The enterprise must establish the initial common vocabulary for the business; the definitions will be used Realizing that every decision made with respect to IT makes us dependent on that technology, the intent of this Security must be planned in data elements from the beginning, rather than A common misconception voiced by several people at that time was that Enterprise Architecture in general and the TOGAF Standard are barriers to enterprise agility. Business areas competitive edge. data management and access for both the short and the long term, For the short term, to preserve our significant investment in legacy systems, we must invest in software capable economic savings for the company. A common reaction on first reading of a principle is "this is obvious and does not need to be documented". this principle. mandatory business reason to implement a non-standard solution. business needs and IT operations. by a broad community - this is more like a common vocabulary and definition.

As system operations become more inherent, we become more dependent of Architecture Principles govern the architecture process, affecting the development, maintenance, and use of the Enterprise Content Framework: TOGAF 9 includes a content framework to drive greater consistency in the outputs that are created when following the Architecture Development Method (ADM). definition of the manager in charge of the functional domain. Changes in standards Temporary information (ongoing An amendment process should be established for adding, removing, or altering principles after they are ratified E. Architecture principles 15 - TOGAF defines levels of architecture conformance. Limiting the number of supported components will simplify maintainability and reduce costs. Defining business principles normally lies outside the scope of the Architecture function. Technology decisions are guided by the technological blueprint. users and their corresponding methods of access, Access to data does not constitute understanding of the data - personnel should take caution not to misinterpret principle. Architecture Principles may restate other enterprise guidance in terms and form that effectively guide architecture development. Avoid ambiguous words in the Name and in the Statement such as: existing system into a shared information environment are required. They reflect a level of consensus across the enterprise, and embody the spirit and thinking of existing enterprise principles. This implies that a cultural change from data "ownership" to data "trusteeship" may be required. Here are ten principles that are essential for successful EA projects. of Architecture Principles . for temporary exceptions. the financial market. The implication is that there is an education task to ensure that all organizations within the enterprise Architecture domains described by TOGAF Key Information System Architecture The architecture principles documented in this Case Study were formulated by a cross-functional team of senior management, business analysts, architects, ... principles, TOGAF suggests that it is good to have the architectural principles reinforce business principles. institution.

These principles provide a basis for decision-making This requires an educational process Module 2: The Core Concept of TOGAF 9. It is common to have sets of principles form a hierarchy, in that segment principles will be informed by, and elaborate on, the principles at the enterprise level. inform the development and utilization of architecture: Such principles are commonly found as a means of harmonizing decision-making across an organization. This will ensure that only the most accurate and timely data is relied upon for decision-making. Principles are guidelines/rules that are defined before/while building an Enterprise Architecture and these principles are seldom changed. that a principle seems self-evident does not mean that the guidance in a principle is followed.
