TOGAF is a framework – a detailed method and a set of supporting tools – for developing an enterprise architecture. It may be used freely by any organization wishing to develop an enterprise architecture for use within that organization. TOGAF is based on iterative process model supported by best practices and re-usable set of existing architectural assets.
TOGAF -The Open Group Architecture Framework.
An architecture in context of TOGAF can be defined 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.
Before you go further we need find answers to below questions
- What is an enterprise?
- Why do I need an enterprise architecture?
- Why do I need TOGAF as a framework for enterprise architecture?
According to TOGAF, an enterprise is a collection of organizations with common set of goals. An enterprise could be a as simple as a single organization or multiple organizations across globe linked under common ownership.
The purpose of enterprise architecture is to optimize across the business processes, integrated environment and support delivery of business vision or strategy.
TOGAF enables an enterprise to standardize and de-risk the architecture development processes and provide workable and economic solutions to address business issues.
TOGAF is divided into 7 parts
Part 1 Introduction
|This part provides a high-level introduction to the key concepts of enterprise architecture and in particular the TOGAF approach. It contains the definitions of terms used throughout TOGAF and release notes detailing the changes between this version and the previous version of TOGAF.|
|Part 2 Architecture Development Methods||This part is the core of TOGAF. It describes the TOGAF Architecture Development Method (ADM) – a step-by-step approach to developing an enterprise architecture.|
|Part 3 ADM Guidelines and Techniques||This part contains a collection of guidelines and techniques available for use in applying TOGAF and the TOGAF ADM.|
|Part 4 Architecture Content Framework||This part describes the TOGAF content framework, including a structured metamodel for architectural artifacts, the use of re-usable architecture building blocks, and an overview of typical architecture deliverables.|
|Part 5 Enterprise Continuum & Tools||This part discusses appropriate taxonomies and tools to categorize and store the outputs of architecture activity within an enterprise.|
|Part 6 TOGAF Reference Models||This part provides a selection of architectural reference models, which includes the TOGAF Foundation Architecture, and the Integrated Information Infrastructure Reference Model (III-RM).|
|Part 7 Architecture Capability Framework||This part discusses the organization, processes, skills, roles, and responsibilities required to establish and operate an architecture function within an enterprise.|
