Roy's Technology Diary

In the previous article, we glanced through Enterprise Architecture as a whole and also discussed the need for an Enterprise Architecture Framework, like TOGAF. With this article we shall continue exploring TOGAF further, and discusses TOGAF's Architecture Development Methodology (ADM). The Architecture Development Methodology (ADM) The Architecture Development Methodology (ADM) provides a proven and repeatable process for developing architectures. The Scope The scope of ADM includes or encompasses the below listed activities, which are generally carried out in iterative cycles of continuous architecture definition and realization; thus aiding a controlled transformation of an enterprises in response to business goals and opportunities - Establishing an architecture framework Developing architecture content Transitioning Governing the realization of architectures Implementation Phases The implementation of ADM could be envisioned across the following phases - Preliminary Initiation...

Lately I've been studying/reading The Open Group Architecture Framework (TOGAF), and I simply could not resist from appreciating the structural approach that it introduces towards envisioning and capturing Enterprise Architecture. I therefore thought of initiating a series of articles herein, with the sole purpose of sharing, simplifying and promoting the framework especially amongst the architecture aspirants out there who follow and read my blog. This write-up, which is the first one in the series, intends to provide a brief overview on Enterprise Architecture and then further goes on to illustrate the need for an Enterprise Architecture Framework. Preface ISO/IEC 42010: 2007 defines "architecture" as: "The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution." TOGAF embraces but does not strictly adhere to ISO/IEC 42010: 2007 terminology. ...
