Structure of the TOGAF Architecture Development Method (ADM). [1] The Open Group Architecture Framework (TOGAF) is the most used framework for enterprise architecture as of 2020 [2] that provides an approach for designing, planning, implementing, and governing an enterprise information technology architecture. [3] TOGAF is a high-level approach ...
Regional target operating model. A regional target operating model is a transformational project with solution covering across regions. It forms regional standards for implementation across regions. This type of model should capture the as-is of the organization design, business capabilities, business processes and supporting technology components.
The first use of the term "enterprise architecture" is often incorrectly attributed to John Zachman's 1987 A framework for information systems architecture. [11] The first publication to use it was instead a National Institute of Standards (NIST) Special Publication [12] on the challenges of information system integration.
An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system. A system architecture can consist of system components and the sub-systems developed, that will work together to implement the overall system. There have been efforts to ...
The Open Group's definition of solution architecture, as provided above, is accompanied by the following three from Scaled Agile, Gartner and Greefhorst/Proper.The Open Group does not recognize the role "solution architect" in its TOGAF skills framework; on the other hand, Glassdoor advertised 55,000 Solution Architect roles in August 2020.
In business and project management, a responsibility assignment matrix [1] (RAM), also known as RACI matrix [2] (/ ˈ r eɪ s i /; responsible, accountable, consulted, and informed) [3] [4] or linear responsibility chart [5] (LRC), is a model that describes the participation by various roles in completing tasks or deliverables [4] for a project or business process.
NIST Enterprise Architecture Model. NIST Enterprise Architecture Model (NIST EA Model) is a late-1980s reference model for enterprise architecture.It defines an enterprise architecture [1] by the interrelationship between an enterprise's business, information, and technology environments.
Systems design is a process of defining and engineering the architecture, methods, and interfaces necessary to accomplish a goal or fulfill a set of requirements. In open systems architecture, the design includes intentional provisions to make it possible to expand or modify the system at a later stage after initial operation.
