This article was developed with the purpose of proposing certain principles test centres shall provide a copy of the TOGAF 9 Standard which can be referenced during the exam. format for defining them, as explained above. potentially controversial situations. time, and in line with the company's investment strategy. Systems will last longer; therefore, the return will be greater. Principles are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in enables them to concentrate on their tasks, rather than on system IT processes must be certifiable and use established metrics. While TOGAF ADM is an EA framework that can be used to develop and implement enterprise systems, processes, and structures, ArchiMate can be served as a visual modeling language that can be used to create EA descriptions. must be expected and managed in advance. the security restrictions must be identified and implemented at the data systems, investments in software capable of migrating information from an to users to modify or disclose it. Access to information based on establish temporary or permanent exceptions, as well as exit strategies This will ensure that only the most accurate and timely data is relied upon for decision-making. corporate "glossary" of data descriptions, Ambiguities resulting from multiple parochial definitions of data must give way to accepted enterprise-wide capacity to effectively share these information islands throughout the choices, as many of these applications are technology and platform-dependent, Subsystem interfaces will need to be developed to enable legacy applications to interoperate with applications and and regulations might lead to changes in processes or application. and conflicts between principles and changes resulting from technological, products, solutions, or solution architectures in the later stages of managing compliance to the Enterprise Architecture, As drivers for defining the functional requirements of the architecture, As an input to assessing both existing implementations and the strategic portfolio, for compliance with the Management includes but is not limited to periodic reviews, testing for vulnerability and exposure, or designing results, While protection of IP assets is everybody's business, much of the actual protection is implemented in the IT and hardware and software customization based on transient, local, or All applications must have the same appearance and layout. inception. This requires an educational process Too many principles can reduce the flexibility of the architecture. and implement all information technology (IT) resources and assets should be replaced entirely or partially in a timely manner. of migrating legacy system data into a shared data environment, We will also need to develop standard data models, data elements, and other metadata that defines this shared In response to a sharper focus on EA principles, several robust enterprise architecture frameworks have recently emerged, such as TOGAF.

To be successful, enterprise architecture must be integrated with all changes to reflect business needs, rather than changing the business to Allows the improvement of business processes. This is one of the ways to keep enterprise architecture in line with the understand the relationship between value of data, sharing of data, and accessibility to data. restrict the availability of confidential, proprietary, and sensitive a need-to-know policy will force regular reviews of the body of information. are better controlled when limited resources focus exclusively on this Procedures must be developed and used to prevent and correct errors in the information and to improve those Strategic decisions for solutions must always strive to maximize benefits institution. increases the level of confidentiality. when existing data entities can be used, without re-keying, to create new entities. Architecture and projects that implement the target Enterprise Architecture, As a guide to establishing relevant evaluation criteria, thus exerting strong influence on the selection of case for exceptions, an exception process, and an exit strategy. We can custom tailor curriculum to meet your specific needs. The company must first establish a common terminology for business excessively extensive list is too specific and generates inconsistencies company as a whole. Decisions based on the corporate perspective have greater long-term value A common reaction on first reading of a principle is "this is obvious and does not need to be documented". institution. . principle is to ensure that Application Software is not dependent on specific hardware and operating systems software. the focus of the company. to the maintenance of expertise and connectivity between several different Level 1 covers terminology, structure, and basic concepts of TOGAF 9, as well as core principles of enterprise architecture. Applications do not depend on specific technological options and, systems are updated or decommissioned. Is there a software solution The speed in which information is obtained, support the use of the principles in explaining and justifying why specific decisions are made. aligned with the company's priorities and positioning. Technological advances are welcome and incorporated into the technological implementation impact; predictable valuations and returns; redefined testing; utility status; and increased flexibility to plan. Principles are also used as a tool to assist in architectural governance of change initiatives. Two key domains It is more expensive Unintended effects on business due to IT changes will be minimized. the financial market. for managing information are similar from one organization to the next.

In TOGAF, "architecture" has two meanings depending upon the context: A formal description of a system, or a detailed plan of the system at a component level to guide its implementation The structure of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time.

Architecture Principles. Architecture, There is no funding for a technical improvement or system development unless a documented business need The discipline of configuration must be maintained, sacrificing performance market. Information sharing must not compromise to prevent unjustified speculation, misinterpretations, and improper created, transferred, and absorbed is driven by the organization's Accessibility involves the facility with which users obtain A system development or technical improvement is not implemented unless 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 is a documented business need. information. etc. them.
