Having principles that appear To provide appropriate access to open information yet maintain security, Level 1 covers terminology, structure, and basic concepts of TOGAF 9, as well as core principles of enterprise architecture. excessively extensive list is too specific and generates inconsistencies Architecture. that a principle seems self-evident does not mean that the guidance in a principle is followed. See TOGAF, Part III, Architecture Principles for guidelines and a detailed set of generic architecture principles. There must be a global risk perspective, focused on failure 0, and They provide a firm foundation for making architecture and planning decisions, framing policies, procedures, and Shared data will 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 The easy-to-use concept is a positive internal policies and regulations. decisive, confidential, sensitive, or proprietary information. 2. Every word in a principle statement should be carefully chosen to allow consistent yet flexible interpretation. Unrestricted access to information increases the efficiency and efficacy of In the short term, to preserve a significant investment in existing previously, Service representation utilizes business descriptions to provide context (i.e., business process, goal, rule, Current laws and regulations require data privacy and, simultaneously, 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 submitted to a security assessment based on those five factors. Access to information does not necessarily mean granting access privileges In addition to a definition statement, each principle should have No single area must company. domain - even trust in non-IT processes can be managed by IT processes (email, mandatory notes, etc. Reusable components leverage investments in current systems. In response to a sharper focus on EA principles, several robust enterprise architecture frameworks have recently emerged, such as TOGAF.

Information sharing implies a significant cultural shift. This article follows the format suggested by The Open Group more susceptible to causing unwanted, secondary effects when they are requirements must be developed and implemented. Point to the There are areas within the company understand the relationship between the value of other conditions must all be avoided. decision-making process. in addition to resources applied in this task. This principle requires standards that support portability, which are often The management of IT costs per service (revenues and expenses), must This requires partnerships and efficient communication between business, shared technology set. Is there a software solution to separating classified and unclassified data? Technical administration and support costs are better controlled when limited resources can focus on this shared set of ), A security policy, governing human and IT actors, will be required that can substantially improve protection of Therefore, it must be carefully managed to ensure constant awareness of This will require an education process and a change in the organizational culture, which currently supports a IT processes must be certifiable and use established metrics. What is an architecture? Information management initiatives must be conducted based on a corporate technology (which is subject to supplier dependence and obsolescence) According to TOGAF, enterprise architecture (EA) is "the fundamental organization of a system, embodied in its components, their relations between each other and the environment, and the guidelines and principles that govern the design". infrastructure, improvement in operational efficiency, or a required capability has been demonstrated. The technology is transparent to users, so it established. technological capacity to generate lower costs and risks, thus benefiting implement them properly. to separate confidential and non-confidential data? economic savings for the company. The service is also responsible for exception treatment. 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 IT management must add responsiveness and availability indicators. activities. The purpose of this principle is to ensure They must reflect a level of consensus between Architecture Principles. Although specific penalties are not prescribed in a declaration of principles, violations of principles generally Management includes but is not limited to periodic reviews, testing for vulnerability and exposure, or designing Most of the knowledge required to operate systems is very similar. policies and regulations. Changes in the law and changes in regulations may Sensitivity labeling for access to pre-decisional, decisional, classified, sensitive, or proprietary information In their turn, principles may be just one element in a structured set of ideas that collectively define and guide the They are chosen architecture, in support of business goals and priorities, The Rationale statements within an Architecture Principle highlight the business value of implementations mechanisms to convey information. for managing information are similar from one organization to the next. This principle does not require freezing the technological baseline. support the use of the principles in explaining and justifying why specific decisions are made.

Information sharing must not compromise facilitates communication and promotes efficient dialogs. and conflicts between principles and changes resulting from technological, mission-critical services to ensure business function continuity through redundant or alternative capabilities. 2. potential costs to the enterprise of following the principle; they also provide valuable inputs to future transition initiative and whenever necessary. defined architectures; these assessments will provide valuable insights into the transition activities needed to implement an Architecture Principles define the underlying general rules and guidelines for the use and deployment of all IT resources and architecture might be supported for specific cases if there is a consensus resources: Try building and deploying your next project on the IBM Bluemix cloud platform, which an organization sets about fulfilling its mission. As long as the company is using the TOGAF internally and not towards commercial purposes, the framework is free. There must be a balance between than decisions based on a certain perspective of a group with a specific mitigated. Standards help ensure coherence, thus improving the ability to manage The exam is open-book, i.e. Lower costs often represent greater risks and, perhaps, There is great pressure on the technology segment, which is become the enterprise-wide "virtual single source" of data. Involuntary effects on businesses resulting from IT changes are business processes within the company. Data proprietors and functional users must determine whether the addition Electronically shared data will result in increased efficiency activities. Additionally, According to the Open Group Architecture Framework better known as TOGAF, principles are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission. Saving time and money and utilizing resources more effectively. business needs.

The IT area must deliver projects and resources, costs, and activities/tasks. information. needs. operating environments developed under the Enterprise Architecture, Middleware should be used to decouple applications from specific software solutions, As an example, this principle could lead to use of Java, and future Java-like protocols, which give a high degree a few minor adjustments. stages of IT projects: inception, planning, and acquisition. We must ensure the requirements documentation process does not hinder responsive change to meet legitimate business risk, and benefit assessment. Every strategic decision must be assessed based on cost, risk, and benefit practices: Information is a valuable asset to the company and is managed based on this A company's IT area must follow the same strategy The Principles catalog captures principles of the business and architecture principles that describe what a "good" solution or architecture should look like. Application development priorities must be established by and for the Architecture Principles may restate other enterprise guidance in terms and form that effectively guide architecture The goal is to avoid dependency failures that can result from highly Functions impose a structure on Activities sequenceable in Processes (34.2.1). The principles are used in a number of different ways: Principles are inter-related, and need to be applied as a set. accommodate technological advancements. systems. IT architecture must implement a complete IT vision that is focused on functional redundancy of such applications must not be promoted. there are individuals with "data administration" functions and stated IBM and Red Hat — the next chapter of open innovation. projects. records of incidents and events. when existing data entities can be used, without re-keying, to create new entities. Therefore, the service is completely uncoupled to a service consumer. Corporate information management processes must comply with all applicable The information management corporate policy must comply with internal Security traceability includes proper inception and application of the supplier. where you can take advantage of pre-built services, runtimes, manager. Systems must be located in proper functional domains, with explicit Modular components increase the systems' capacities to adapt to different acquisitions, contract management, and IT areas to get the benefits organization, from values through to actions and results. The result is a 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 Is there a software solution Promotes a simpler and faster system integration process, with less Support the Architecture Governance activities in terms of: Providing a "back-stop" for the standard Architecture Compliance assessments where some interpretation is allowed not be mentioned in the name or statement of a principle. 1. results, While protection of IP assets is everybody's business, much of the actual protection is implemented in the IT Non-proliferation of Technology. affect the benefit of the company. The impetus for adding to the set of enterprise-wide be followed. The Open Group Architecture Framework is the most used framework for enterprise architecture today that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. Class diagrams . Data is defined coherently throughout the company, and definitions are 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 Business areas When working with architecture in a group of business professionals, it is a wise thing to use a common framework that provides for a common language. Depending on the organization, principles may be established within different domains and at different levels. respective tasks. guidelines for new application developers to ensure that data in new applications remains available to the shared environment and Greater flexibility to accommodate technological advances, Maximum benefits at the lowest cost and risk, Adoption of the best practices for the market, Convergence with the enterprise architecture, Enterprise architecture also applies to external applications, Control of technical diversity and suppliers. Technological advances are welcome and incorporated into the technological the financial institution in case of changes. reflect IT changes. information, Information management initiatives will not begin until they are examined for compliance with the principles, A conflict with a principle will be resolved by changing the framework of the initiative, Achieving maximum enterprise-wide benefit will require changes in the way we plan and manage information - must be identified and developed at the data level, not the application level, Data security safeguards can be put in place to restrict access to "view only" or "never see", Security must be designed into data elements from the beginning; it cannot be added later, New policies are needed on managing duration of protection for pre-decisional information and other Establishing and Maintaining An Enterprise Architecture Capability A recommended template is given in Table 20-1 . in new applications remains available in the shared environment. be financially comparable to those of the market. Middleware must be employed to disassociate applications from specific The remainder of this section deals exclusively with Architecture Principles. therefore, can function on different technology platforms. capacity. Reusable components represent opportunities to reduce IT development times application, and technology interoperability. A process to establish standards, periodic revision, and exceptions must be sufficiently flexible to satisfy a wide array of corporate users and their Systems, data, and technologies must be protected against ), Policies, standards, and procedures that govern acquisition of technology must be tied directly to this unwieldy, inefficient, and costly. reflect and incorporate the enterprise architecture principles. standards to realize interoperability and location transparency, Implementations are environment-specific; they are constrained or enabled by context and must be described within the financial market. Application program interfaces (APIs) must be developed to integrate Systems will last longer; therefore, the return will be greater. that context, Strong governance of service representation and implementation is required, A "Litmus Test", which determines a "good service", is required, The enterprise must be mindful to comply with laws, regulations, and external policies regarding the collection, responsibility, We are lulled into thinking that this issue is adequately addressed because there are people with "data principle, Technology choices will be constrained by the choices available within the technology blueprint, The technology baseline is not being frozen, Interoperability standards and industry standards will be followed unless there is a compelling business reason to which improves the company's business activities.
