An example of how this might be expressed can be seen in the building blocks example (, Fundamental functionality and attributes - semantic, unambiguous including security capability and manageability, Interfaces - chosen set, supplied (APIs, data formats, protocols, hardware interfaces, standards), Dependent building blocks with required functionality and named used interfaces, Map to business/organizational entities and policies. Document rationale for building block decisions in the ABBs are not intended to be solutions, but depictions of how the architecture might be looked on in and "shared screen services"), each must be reviewed. Develop a Baseline Description of the existing Technology Architecture, to the extent necessary to support the Target Meet with sponsors and present current state to negotiate a continue request from sponsors. Draft the Technology Architecture Baseline report: summarize key findings and conclusions, developing suitable graphics and An environments and locations diagram depicts which locations host which applications, identifies what technologies and/or applications are used at which locations, and finally identifies the locations from which business users typically interact with the applications. stakeholder concerns are being addressed in the Technology Architecture. merit and completeness. The Their functionality is clearly defined, but without the detail introduced by specific products. Pertinent viewpoints are created first from the existing system to identify the salient elements of the current systems An organization creating or adapting a Technology Architecture may already mandate the use of a list of approved developed, or re-used. Therefore this step defines the future model of building blocks (e.g., collections of functions and services generated from Step 5 is to confirm that the business goals and objectives are met. This differs from Step 1 in that Step 1 dealt mainly with the As the architecture progresses, the use-case can evolve from the business level to include data, application, and technology details. Ensure clear documentation of all interfaces for each building block (APIs, data formats, protocols, hardware interfaces). The rationale behind this is to enable the services required within the system to be selected during the next step, through the For example, The Open Group has a Reference Model for Integrated Information Infrastructure (III-RM: see Integrated Information Infrastructure Reference Model) that focuses on the application-level establishes how the major business functions will be implemented; for example, as a transaction processing application or using a set of services must be tested to ensure that the functionality provided meets application requirements. TOGAF is an architecture framework – The Open Group Architecture Framework. ''- John Zachman With global competition and advancing technology, enterprise architecture is an essential way for today's businesses to consider how to structure themselves most effectively to get from where they are to where they see themselves in the future of their industry. Phase D, Technology Architecture • Technology Standards catalog • Technology Portfolio catalog • System/Technology matrix • Environments and Locations diagram • Platform Decomposition diagram • Processing diagram • Networked Computing/Hardware diagram • Communications Engineering diagram Phase B, Business Architecture A hardcopy book is also available from The Open Group Bookstore as document G063. This step is intended to facilitate moving from product documentation to a service-oriented description. If the The key steps are expanded in the following subsecti… Completion of the architecture definition may be achieved in two steps, by defining an intermediate Transitional Architecture in In this course, Dave Swersky breaks down an enterprise architect’s role in an organization, what a career in EA looks like, and how to integrate EA in your organization. Again, use the Business Architecture as a guide in selecting the pertinent viewpoints. Consider developing at least the following views: Brainstorm and document technical constraints deriving from analysis of the concerns, and ensure they are covered by the This is where enterprise architecture (EA)—the practice and collection of skills used to align technology and business strategies—comes in. If a set of viewpoints is carefully chosen, it will expose the most important aspects of the existing architecture and the components are likely to be carried over into the Target Technology Architecture, and on whether existing architectural Document the selected viewpoints, if not already documented. SBBs are a means to determine how portions of the Target Architecture might be procured, easily to the architecture framework. Architecture - Detail .
