TOGAF: OFFERS TECHNIQUES TO SUPPORT THE APPLICATION OF THE ADM.

TOGAF reflects the structure and content of an architecture capability within an enterprise.

TOGAF covers the development of various related types of architecture. These various types of architecture are commonly accepted as subsets of an overall enterprise architecture, all of which TOGAF is intended to support.

 

Central to TOGAF is the Architecture Development Method (ADM), The architecture capability operates the method. The method is supported by a number of guidelines and techniques. This produces data to be stored in the repository, which is classified according to the Enterprise Continuum (documented in TOGAF, Part V). The repository is initially populated with the TOGAF Reference Model.

TOGAF embraces and extends this definition. In TOGAF, “architecture” has two meanings depending upon the context:

1. A proper description of a system, or a detailed plan of the system at a component level to guide its implementation

2. The structure and formation of components, their inter-relationships, and the principles and guidelines governing their design and evolution over time

 

The ADM is the major component of TOGAF course and provides guidance for architects on a number of levels:

• It provides a number of architecture development phases (Business Architecture, Information Systems Architectures, Technology Architecture) in a cycle, as a complete process template for architecture development activity.

• It provides description of each architecture phase, describing the phase in terms of objectives, approach, inputs, steps, and outputs. The inputs and outputs sections provide a definition of the architecture content structure and deliverables (a detailed description of the phase inputs and phase outputs is given in the Architecture Content Framework).

• It provides cross-phase summaries that envelop requirements management.

 

TOGAF course provides a number of guidelines and techniques to support the application of the ADM. The guidelines concentrate on adapting the ADM to deal with a number of usage scenarios, including various process styles (e.g., the use of iteration) and also particular specialty architectures (such as security). The techniques support specific tasks within the ADM (such as defining principles, business scenarios, gap analysis, migration planning, risk management, etc.)  TOGAF course also provides a model for structuring a virtual repository and provides methods for classifying architecture and solution artifacts, showing how the different types of artifacts develop, and how they can be leveraged and re-used. This is based on architectures and solutions (models, patterns, architecture descriptions, etc.) that exist within the enterprise and in the industry at large, and which the enterprise has collected for use in the development of its architectures.

It also includes a set of resources, guidelines, templates, background information, etc. provided to assist the architect establish an architecture practice within an organization.

 

 

As an independent supplier of training, the knowledge academy has the ability to quickly adapt to changing client needs by adopting state-of-the-industry development and delivery technology. This adaptive and agile nature has confirmed to be critical for survival in a technology driven world — where learners demand to consume training when and where they want (desktop or mobile) on the devices they choose to use.
