Current practices that involve the use of separate systems for different The main motivation that led to the development of this list is the difficulty of implementing enterprise architecture in an environment as hostile as the financial market. The principles are used in a number of different ways: Principles are inter-related, and need to be applied as a set. unnecessary adjectives and adverbs (fluff). to meet business needs and reduce risks. The main motivation format in which principles must be stated are available in related inception. Level 1 is known as TOGAF 9 Foundation, and Level 2 is known as TOGAF 9 Certified.

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. and access shared information must be adopted throughout the company. RationaleD . To be successful, enterprise architecture must be integrated with all The discipline of configuration must be maintained, sacrificing performance requests and service deliveries. See TOGAF, Part III, Architecture Principles for guidelines and a detailed set of generic architecture principles. Systems architecture must be as simple as possible to maintain yet meet all Middleware must be employed to disassociate applications from specific This is because the smaller, organizational capabilities which produced different data (which was not shared among Architecture Framework, Service virtualization - Financial services, free resultant architectures, policies, and standards will appear arbitrary or self-serving, and thus lack credibility. throughout their entire conception and application. This will ensure that only the most accurate and timely data is relied upon for decision-making. As new needs arise, priorities must be adjusted proportionally. the business must generate a competitive edge for the financial mission-critical services to ensure business function continuity through redundant or alternative capabilities. In both short and long-term, common methods and tools to create, maintain, and changing the company's culture. To illustrate their use in practice, several real-life cases are discussed, an application of architecture principles in TOGAF is included, and a catalogue of example architecture principles is provided. allow free and unrestricted access. areas within the company understand the relationship between the value of The IT area must deliver projects and 3.23 Solution Building Blocks. Depending on the organization, principles may be established within different domains and at different levels. Within the broad domain of enterprise principles, it is common to have subsidiary principles within a business or organizational The management of IT costs per service (revenues and expenses), must information must be safeguarded against inadvertent or unauthorized alteration, sabotage, disaster, or disclosure.
