The enterprise life cycle is a key concept in enterprise architecture (EA), enterprise engineering [2] and systems engineering. [3] The Enterprise Architecture process is closely related to similar processes, as program management cycle or systems development life cycle, and has similar properties to those found in the product life cycle.
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 ...
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
PERA is a reference architecture that can model the enterprise in multiple layers and in multiple stages of the architectural life cycle. Initially PERA was part of the PERA methodology, which consisted of three main building blocks: [2] Purdue Enterprise Reference Architecture, Purdue Reference Model, and; Purdue implementation procedures manual
Fig 1. GERAM Framework: This set of components is identified in the first image and briefly described in the following. Starting from defined concepts to be used in enterprise integration (GERA), GERAM distinguishes between the methodologies for enterprise integration (GEEM) and the languages used to describe structure, contents and behaviour of the enterprise (GEML).
A framework provides a structured collection of processes, techniques, artifact descriptions, reference models, and guidance for the production and use of an enterprise-specific architecture description. [citation needed] Paramount to changing the EA is the identification of a sponsor.
