IT ENTERPRISE ARCHITECTURE
Enterprise Architecture using “TOGAF”

Оглавление

The main area for TOGAF application is the software infrastructure of the information system. It best suits for describing the integration components used to support a wide range of critical enterprise applications for business. The model can be described as:

• Business architecture overview;

• Description of the current system with the level of detail required;

• Identification and description of elementary architectural blocks to be used in the new architecture;

• Development of a draft technical report;

• Submitting the draft report for review.


TOGAF is positioned not as a reference model, but a “tool for developing information system architectures”. The primary function is to speed up and facilitate the process of developing the architecture of a particular organization, providing the possibility of future development. Let us consider building of the Enterprise Architecture based on the TOGAF methodology in more details, which in my opinion has several advantages:

• TOGAF approach allows you to build the entire architectural process – from the launch of the practice to the results.

• TOGAF is the de facto standard and has a certification program.

• TOGAF is absolutely free and has lots of open resources to download and use.

• TOGAF contains a complete set of tools for creating and developing architectural practices in an organization. There is a step-by-step process for developing a description of the Enterprise Architecture and a complete range of tools, templates, etc.

• TOGAF is compatible with other frameworks, for example, “Zahman Framework”. As an architectural process, the TOGAF model supplements the Zachman model classified as an architectural taxonomy. Zachman demonstrates how to classify the artifacts. The TOGAF model describes their creation.

Even though the TOGAF methodology and Zakhman infrastructure are merged into the “enterprise infrastructures” category, their principles, structures and competencies are different. TOGAF is a functional and dynamic infrastructure including guidelines for process use patterns. While the Zachman framework is a static architecture structure, it is the most effective one for applying the analysis and meta-analysis of infrastructure frameworks. Despite the significant differences in these frameworks, they can be used together.
