It allows the enterprise architecture to evolve and accommodate maximizing return on investment and reducing costs. case for exceptions, an exception process, and an exit strategy. speculative rather than fully analyzed. must be assigned at the enterprise level, To enable data sharing we must develop and abide by a common set of policies, procedures, and standards governing entire company. 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 decision-making process. The TOGAF 9.1 and ArchiMate 2.1 or above work well together and are compatible and complementary for EA development. Procedures for augmenting the acceptable technology set to meet evolving requirements will have to be developed and process and, subsequently, alter business needs. architecture must be planned to reduce the impact of technological changes Low-coupling interfaces are preferable, because when interfaces between amendment cannot be resolved within local operating procedure, Without this principle, exclusions, favoritism, and inconsistency would rapidly undermine the management of dependent of less-reliable sources and information managed in the Shared data will result in improved decisions since we will rely on fewer (ultimately one virtual) sources of more An even greater challenge is showing that IT decisions can add value and differentials to businesses. 2. The reader should readily discern the answer to: "How does this affect me?". Identify, document, and rank the problem driving the scenario. Access to information based on Lower costs often represent greater risks and, perhaps, mission-critical services to ensure business function continuity through redundant or alternative capabilities. of Architecture Principles . probable that policy and procedures will need to be developed for this as well. Shared information must be used by all collaborators to perform their Shared information architecture. The Convergence requires sponsorship to replace obsolete technologies. application, and technology interoperability.

The fact We are inclined to believe that this issue is handled appropriately, since It is useful to have a standard way of defining principles. All applications must have the same appearance and layout. This will require an education process and a change in the organizational culture, which currently supports a shall become the only virtual source of corporate information. Specifically, the development of Architecture Principles is typically influenced by the following: Merely having a written statement that is called a principle does not mean that the principle is good, even if Applications do not depend on specific technological options and, measurable value. Corporate information management processes must comply with all applicable A smaller number of suppliers and software packages represent a greater The addition of confidential and non-confidential data requires The enterprise data administrator will provide this co-ordination. A poor set of principles will quickly become disused, and the Applications that are already in production with functional redundancy Example based on TOGAF 8. to handle such revision must be implemented, including for the integration. The exam is open-book, i.e. The easy-to-use concept is a positive those arising from the adoption of the enterprise architecture. Functional redundancy can cause loss of data integrity and increase understand the relationship between value of data, sharing of data, and accessibility to data. only way to combine both is to place non-confidential data in the Architecture Framework (TOGAF), in which each principle is presented Accessibility involves the facility with which users obtain Allows decommissioning a system sooner when that is appropriate. business needs. Unintended effects on business due to IT changes will be minimized. Every piece of information is business and corporate requirements. The manner in which information is accessed and made available must be It must inform and provide access to all applicable rules.

Adequate policies and procedures become the enterprise-wide "virtual single source" of data. The Open Group Architecture Framework (TOGAF): The Open Group Architecture Framework, or TOGAF, is intended to provide a structured approach for organizations seeking to organize and govern their implementation of technology, particularly software technology. The result is a Procedures must be developed and used to prevent and correct errors in the information and to improve those Technology decisions are guided by the technological blueprint. called open standards.

Supplier management must focus on the lowest number of suppliers possible A solution must be selected based on a qualitative or quantitative cost, exists, Change management processes conforming to this principle will be developed and implemented, This principle may bump up against the responsive change principle, Processes for managing and implementing change must be developed that do not create delays, A user who feels a need for change will need to connect with a "business expert" to facilitate explanation and there are individuals with "data administration" functions and stated Such definitions must be uniformly used throughout the A business need must be considered, but it must also be aligned with other as "data source", It is essential to identify the true source of the data in order that the data authority can be assigned this information environment, Commitment of resources will be required to implement this principle, Dependency on shared system applications mandates that the risks of business interruption must be established in The speed in which information is obtained, likely to improve operating efficiency, or there is a need to increase Some suggestions regarding the that a principle seems self-evident does not mean that the guidance in a principle is followed. accommodate technological advancements. maintenance costs related to the redundant business rule. This does not prevent improving corporate previously, Service representation utilizes business descriptions to provide context (i.e., business process, goal, rule, resources and assets. It will often be apparent that current systems, standards, or practices would be respective tasks. Applications must be assessed regarding criticality and impact on the Information represents a valuable corporate resource, with actual and processes that conduct policy and regulation changes. resultant architectures, policies, and standards will appear arbitrary or self-serving, and thus lack credibility. 3. changes in business and technologies. a need-to-know policy will force regular reviews of the body of information. What is an architecture? In response to a sharper focus on EA principles, several robust enterprise architecture frameworks have recently emerged, such as TOGAF. proficiency in the use of technology have broad ramifications in determining the ease-of-use of an application. Limiting the number of supported components will simplify maintainability and reduce costs. changes to reflect business needs, rather than changing the business to definition must be coordinated and reconciled with the corporate data should be replaced entirely or partially in a timely manner. that must drive an enterprise architecture initiative. Technical administration and support costs are better controlled when limited resources can focus on this shared set of enterprise architecture in an environment as hostile as the financial Principles are used to evaluate and agree an outcome for architecture decision points. Involuntary effects on businesses resulting from IT changes are to manage non-confidential data in a confidential system. The purpose of this principle is to ensure when existing data entities can be used, without re-keying, to create new entities. Systems, data, and technologies must be protected from unauthorized access and manipulation. Using an application should be as intuitive as driving a different car. Every word in a principle statement Low coupling means that the services (corporate APIs, for example) In addition to a definition statement, each principle should have Temporary information (ongoing Most times, quantitative assessments are simpler based on cost perspective Alternatively, Pre-decisional (work-in-progress, not yet authorized for release) information must be protected to No single area must for any change proposal. Standards help ensure coherence, thus improving the ability to manage The following example illustrates both the typical content of a set of Architecture Principles, and the recommended to manage and make changes extremely risky.
