We'll be looking at some of the most important examples below. This document details the Architecture Principles to which the organization adheres. There are four architectural domains in TOGAF 9.1 that offer specializations for businesses. mission-critical services to ensure business function continuity through redundant or alternative capabilities. It is vital that the principles statement is infrastructure, improvement in operational efficiency, or a required capability has been demonstrated. This is an example set of templates for the TOGAF 9 standard. The Open Group Architecture Framework (TOGAF) is an enterprise architecture methodology that offers a high-level framework for enterprise software development. A TOGAF principle always has a: Of the 21 principles, there are four different domains (or subsets) of TOGAF architecture principles: Each of these subsets contains specific enterprise architect principles regarding that domain and its operations. One option is for each team involved with processing data to conduct self-assessments against agreed data principles and standards. Data is an Asset. Essentially, View data as a shared asset. This implies that a cultural change from data "ownership" to data "trusteeship" may be required. Principles are guidelines/rules that are defined before/while building an Enterprise Architecture and these principles are seldom changed. by a broad community - this is more like a common vocabulary and definition. Technology Principles. implementation of that need, If changes are going to be made, the architectures must be kept updated, Adopting this principle might require additional resources, This will conflict with other principles (e.g., maximum enterprise-wide benefit, enterprise-wide applications, defined architectures; these assessments will provide valuable insights into the transition activities needed to implement an Electronically shared data will result in increased efficiency Too many principles can reduce the flexibility of the architecture. Architecture Principles are used to capture the fundamental truths about how the enterprise will use and deploy IT A common reaction on first reading of a principle is "this is obvious and does not need to be documented". 1. TOGAF is the de facto industry standard framework, offering a methodological approach to Enterprise Architecture design, planning, implementation, and governance. Architecture Principles are general rules and guidelines, intended to be enduring and seldom amended, which informs and supports the way in which an organization sets about fulfilling its mission. easily accessible, Stewards must have the authority and means to manage the data for which they are accountable, We must make the cultural transition from "data ownership" thinking to "data stewardship" thinking, The role of data steward is critical because obsolete, incorrect, or inconsistent data could be passed to speculative rather than fully analyzed.
