Investing into information system involves a lot of money. Just like in planning to build a house, information systems within an enterprise would need planning and designing.
A framework that outlines the detailed method and set of supporting tools used for developing enterprise architecture is known as The Open Group Architecture Framework (TOGAF). With TOGAF, organizations are able to design, evaluate and build the architecture appropriate for their organization. The members of The Open Group developed the TOGAF. The used of TOGAF is free to any organization.
TOGAF has four types of architecture or framework commonly accepted as subsets of an overall architecture:
1. Business Architecture – describes the business strategy, governance, organization, and key business processes.
2. Data Architecture – explains the organization’s logical and physical data assets and data management resources structure.
3. Applications Architecture – supplies the blueprint for the individual application systems to be set up, their links, and their relationships to the core business processes of the organization
4. Technology Architecture – explains the logical software and hardware capabilities required to support the deployment of business, data, and application services within the organization. This covers IT infrastructure, middleware, networks, communications, processing, standards, etc.
Any organization that wishes to undertake or plans to undertake the design and implementation of enterprise architecture will benefit from the use of TOGAF. They are ensured of a design and a procurement specification, which will facilitate the open systems implementation, thus enabling organizations to reduce risk due to the benefits of the open systems. TOGAF is the most common sense, practical, prudent, and effective method in the development of enterprise architecture.
