TOGAF

from Wikipedia, the free encyclopedia

The The Open Group Architecture Framework ( TOGAF ) provides an approach for the design, planning, implementation and maintenance of enterprise architectures . As the operational framework of the Government and Agency Frameworks group, TOGAF offers the Architecture Development Method (ADM), a process model for the development of technical architectures.

TOGAF is being further developed by the Open Group . The first version of TOGAF, published in December 1995, was based on the TAFIM (Technical Architecture Framework for Information Management) developed by the United States Department of Defense . On this basis, the Open Group further developed TOGAF; the current status is published on the Open Group's website.

The Open Group offers TOGAF free of charge for internal use to develop a company architecture.

Structure for describing the corporate architecture

When using TOGAF, the company architecture is usually modeled in the three domains of business architecture , information system architecture (consisting of application architecture and data architecture ) and technology architecture .

  • Business architecture: The business architecture considers the strategy, the organizational structure, the business processes and the business capabilities of the company. The business process architecture is the result of business process modeling .
  • Information system architecture:
  • Data architecture: In the data architecture, the data and their relationships, which are required for the implementation of business processes, are identified and described. This takes place in a model and a form of representation that is stable, complete, consistent and understandable for all parties involved (see data model ). The information architecture represents information, information groups and their information needs. Various roles that have the same information needs (e.g. controller) are summarized under information groups.
  • Application Architecture: Inside the application architecture are applications managed, which are necessary for the execution of business processes. In addition to the inventory management of all applications, the relationships and interfaces between the applications are also considered in the context of the application architecture. The applications are categorized based on their technical functionality and the information processed by them . These categories are relatively stable. The specific applications that are used within the categories are replaced more frequently. This change results from further technical developments and changed requirements.
  • Technology architecture : The technology architecture describes the architectural elements for setting up and operating the IT infrastructure . It defines the basis on which applications can be procured, integrated and operated.

These basic architectures can be supplemented by other architectures, depending on the perspective, for example the security architecture (description of the security processes , security systems and the tasks of the organizational units involved with which the information security suitable for the organization is achieved) and the operating architecture (operation and management of the software, Hardware and communication infrastructure).

Architecture development

Architecture Development Method (ADM) - The TOGAF architecture development process
Architecture Development Method (ADM) - The TOGAF architecture development process

TOGAF defines an architecture development process: the Architecture Development Method (ADM). The architecture is updated through the iterative execution of this process.

The process consists of eight phases: In phase A (architecture vision), the goals and the parties involved in updating the corporate architecture are defined. In phases BD, the respective actual and target architecture are described for the business, information system (application and data architecture) and the technology architecture. The decisive differences are worked out. In phase E, the projects that are necessary for the transfer of the actual architecture into the target architecture are defined. Phase F serves to describe the overarching cooperation between the individual projects; these agreements are monitored in Phase G. In phase H requirements and external influences are collected, they then serve as the basis for the next ADM run.
