TOGAF, The Open Group Architecture Framework, has laid out an example set of 21 high-quality architecture principles. The set of principles must be expressed in a way that allows a balance of interpretations. IT infrastructure must also be optimized based on business requirements and Architecture Principles may restate other enterprise guidance in terms and form that effectively guide architecture development. put in place. Currently, the only way Such definitions must be uniformly used throughout the 3.3.1 Developing Architecture Principles IT processes must be certifiable and use established metrics.
