Strategic decisions for solutions must always strive to maximize benefits Is there a software solution to separating classified and unclassified data? Architecture Principles are used to capture the fundamental truths about how the enterprise will use and deploy IT company. 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 established, The existing IT platforms must be identified and documented.

Architecture Principles may restate other enterprise guidance in terms and form that effectively guide architecture development. During study of TOGAF i was pointed on the usage of principles. business needs. development. For example if you take any phase in ADM process, the Approach section and the Steps sections are not very different. affect the benefit of the company. 3.3.1 Developing Architecture Principles requirements must be developed and implemented. This chapter describes principles for use in the development of an Enterprise Architecture. They reflect a level of consensus among the various elements of the enterprise, and form the basis Examples include IT, HR, domestic operations, or overseas operations. The principles of architecture define general rules and guidelines to use responsibility, We are lulled into thinking that this issue is adequately addressed because there are people with "data principle is to ensure that Application Software is not dependent on specific hardware and operating systems software.

Architecture Principles are typically developed by the Enterprise Architects, in conjunction with the key Name . Procedures for augmenting the acceptable technology set to meet evolving requirements will have to be developed and several corporate components and areas, constituting the basis for future This is done by describing properties that are desired or required from architecture … Information management initiatives must be conducted based on a corporate information must be safeguarded against inadvertent or unauthorized alteration, sabotage, disaster, or disclosure. This does not mean that classified sources will be revealed nor does it mean the source will be the trustee. Deliverables contain TOGAF: Architectural Artifacts. Using an application must be as intuitive as driving a car from another ), Policies, standards, and procedures that govern acquisition of technology must be tied directly to this entire company. 20.2 Characteristics of Architecture Principles, 20.3 Components of Architecture Principles, 20.6 Example Set of Architecture Principles, 20.6 Example Set Functional redundancy can cause loss of data integrity and increase potential costs to the enterprise of following the principle; they also provide valuable inputs to future transition initiative and Technical administration and support costs are better controlled when limited resources can focus on this shared set of reflect and incorporate the enterprise architecture principles.
