An Enterprise Architecture Framework Diagram is a classification scheme of architectures and their important artifacts. Enterprise Architecture in a Nutshell If you do a search on Google with the question “What is Enterprise Architecture?” you will find many articles telling you that there is no universally agreed-upon definition. Enterprise architecture identifies the structure and the strategy of the enterprise (the city function in our analogy). Enterprise architecture, when performed in a disciplined agile manner, is an important enabler of agile software delivery. In other words, Enterprise Architecture is not a business strategy, planning or management methodology. Therefore, any attempts to change or expand the city can go awry if the proper considerations have not been made – and do-overs are expensive. Enterprise architecture (EA) is a comprehensive operational framework that explores all of an organizations functional areas while defining how technology benefits and serves the organization's overall mission. Most organizations aren’t able to manage their enterprise architecture on their own. Enterprise Architecture frameworks typically include: Agile – An iterative approach to planning and guiding project processes.

Business Capability Modeling – A technique for the representation of an organization’s business anchor model, independent of the organization’s structure, processes, people or domains. Each framework possesses different strengths and weaknesses. Due to their scope, cities tend to have a lot of moving parts that operate well and in coordination with each other. Business architecture addresses the questions WHAT and WHO: For many years, it has been common to regard the architecture domains as layers, with the idea that each layer contains components that execute processes and offer services to the layer above. EA helps develop an understanding of where Big Data fits into operations and processes and prioritize these initiatives with data governance sources and analytics in mind. This plan makes it easier to manage and gives all staff the information they need. This could be data of the kind of account, employee or organization. There are different visions of what enterprise architecture actually means and a variety of standards for its representation. The TOGAF 9.1 specification clarified, that, "A complete enterprise architecture description should contain all four architecture domains (business, data, application, … Framework – Conventions, principles and practices for the description of architectures established within a specific domain of application and/or community of stakeholders.

Coronavirus (COVID-19) is an unexpected driver validating the effectiveness of EA in an organization. The four commonly accepted domains of enterprise architecture are: Business architecture domain – describes how the enterprise is organizationally structured and what functional capabilities are necessary to deliver the business vision. Enterprise architecture (EA) is a strategic planning initiative that helps align business and IT. Policies are used to direct decisions, and to ensure consistent and appropriate development and implementation of Processes, Standards, Roles, Activities, IT Infrastructure etc. Enterprise architecture is a strategic and comprehensive blueprint for how IT infrastructure will be used across an organization to help meet that organization’s goals.

Product Lifecycle Management – A philosophy, process, and discipline supported by software for managing products through the stages of their life cycles, from concept through retirement. It emphasizes the generality of interfaces (user interfaces and APIs) via five fundamental generic interface constraints: resource identification (e.g., uniform resource identifier [URI]), manipulation of resources through representations (e.g., HTTP), self-descriptive messages (e.g., Multipurpose Internet Messaging Extensions [MIME] types), hypermedia as the engine of application state (e.g., links) and application neutrality. To account for this, standardized EA methodologies are commonplace. Over the years, people have developed literally dozens of different frameworks, some of which are designed for a particular niche type of organization.Often, these frameworks view enterprise architecture in terms of layers. Has at least a supporting rationale and a measure of importance. In particular, they are a key element in a successful architecture governance strategy. WHO is executing defined business services or capabilities? SOA reduces redundancy and increases usability, maintainability, and value. This is true for several reasons: 1. An Architecture View consists of one or more Architecture Models. Examples of viewpoints: operational, systems, technical, logical, deployment, process, information. The scope of enterprise architecture includes: the people, business processes, information and technology of the enterprise, and their relationships to one another and to the external environment. The intent of enterprise architecture is to determine how an organization can effectively achieve its current and future objectives.

They attempt to address the basic challenge of assessing, aligning, and organizing business objectives with technical requirements and strategies such as the Zachman Framework, The Open Group Architecture Framework (TOGAF), NAF, DoDAF, MoDAF and etc. Usually delivered as a document or architectural model describing the business capabilities as they are, and the changes planned over the course of a future period of time. Enterprise architecture applies architecture principles and practices to guide organizations through the alignment of these architecture domains: business, information, process, and technology. The plan must comply with regulations – such as zoning laws – and be mindful of the city’s current state and its infrastructure. The term derives from the phrase “separation of concerns” as originally coined by Edsgar Dijkstra. Each project has a life cycle that typically includes specific project phases: initiation, planning, execution, and closure. Enterprise Architecture is a rigorous approach for describing the structure of an enterprise. Many EA frameworks combine data and application domains into a single information system layer, sitting below the business and above the technology (the platform IT infrastructure). Business architecture addresses the questions WHAT and WHO: WHAT is the organization’s business vision, strategy, and objectives that guide creation of business services or capabilities? The aim is to successfully execute business strategies. erwin Evolve provides organizations with a central source of truth and the ability to see how seemingly independent artifacts are actually interdependent.
