By 1997, Zachman had renamed and refocused his ISA framework as an EA framework; it remained a classification scheme for descriptive artifacts, not a process for planning systems or changes to systems. The business mission is the primary driver. EA is also used in system development, IT management and decision-making, and IT risk management to eliminate errors, system failures and security breaches. According to CompTIA, these are the four leading Enterprise Architect Planning (EAP) methodologies: These are just four of the most commonly referenced and recognized EA methodologies, but others exist. TOGAF 9.1 White Paper An Introduction to TOGAF Version 9.1. EA helps businesses structure IT projects and policies to achieve desired business results and to stay on top of industry trends and disruptions using architecture principles and practices, a process also known as enterprise architectural planning (EAP). FEAF was a process much like TOGAF's ADM, in which “The architecture team generates a sequencing plan for the transition of systems, applications, and associated business practices predicated upon a detailed gap analysis [between baseline and target architectures].”. Environment (the external entities and activities monitored, supported or directed by the business). Organization of architects: guidance on the team structure and the governance of the team, including the skills, experience, and training needed. Finally the technology to implement the applications. Given IBM already employed BSP, Zachman had no need to provide planning process. Then the applications built to store and provide that data. This book emphasises the need for enterprise architects to focus on core business processes ("Companies excel because they've [decided] which processes they must execute well, and have implemented the IT systems to digitise those processes.") It introduced structured analysis, after information technology engineering, which features, for example, mappings of organization units to business functions and data entities to business functions. At that point, the processes in TOGAF, FEAF, EAP and BSP were clearly related. EA is especially useful for large businesses going through digital transformation, because it focuses on bringing legacy processes and applications together to form a more seamless environment. Infomet - conceived by Pieter Viljoen in 1990, Pragmatic Enterprise Architecture Framework (PEAF), This page was last edited on 11 November 2020, at 06:52. Enterprise Architecture Planning is a data-centric approach to architecture planning. You’ll also need hands-on experience working with computer systems, hard drives, mainframes and other architecture technology. TOGAF, ASSIMPLER, EAF) include most of the above. A view model is a framework that defines the set of views or approaches used in systems analysis, systems design, or the construction of an enterprise architecture. In 2001, the US Chief CIO council published A practical guide to Federal Enterprise Architecture, which starts, “An enterprise architecture (EA) establishes the Agency-wide roadmap to achieve an Agency’s mission through optimal performance of its core business processes within an efficient information technology (IT) environment." Enterprise architecture (EA) is the practice of analyzing, designing, planning and implementing enterprise analysis to successfully execute on business strategies. Enterprises may have millions of instances of data entities. Microsoft Excel and PowerPoint are the two most basic tools you’ll use for enterprise architectural planning. In 1987, John Zachman, who was a marketing specialist at IBM, published the paper, A Framework for Information Systems Architecture.

Camarinha-Matos, H. Afsarmanesh, Collaborative Networks: Reference Modeling, Springer, 2008. In 2013, TOGAF[19] is the most popular Architecture framework (judged by published certification numbers) that some assume it defines EA. The NIST Enterprise Architecture Model seemingly was the first publication that consistently used the term "Enterprise Architecture". To become an enterprise architect, you’ll need an undergraduate degree in computer science, information technology or a related field and at least 10 years of experience in IT or a related field. The Class, subject and entity forms a hierarchical view of data. Enterprise architects need several soft skills to be successful, including communication, problem-solving, critical thinking, leadership and teamwork. The data view starts with the data classes which can be decomposed into data subjects which can be further decomposed into data entities. "[10] However, in this article the term "Enterprise Architecture" was mentioned only once without any specific definition and all subsequent works of Zachman used the term "Information Systems Architecture".
