Together, the frameworks can complement each other, with TOGAF describing the detailed process for creating the Enterprise Architecture, and Zachman categorizing the artefacts. The open nature of the framework, allows organizations to prevent a vendor lock-in with proprietary Enterprise Architecture solutions, allowing them to scale and adapt without running into significant cost, security, and technology-integration issues. It is the integration of answers to these questions that enables the comprehensive, composite description of complex ideas. The stakeholders are generally grouped as planners, owners, designers (architects), implementers, sub-constructors, users, or sometimes represented as viewpoints: scope context, business concepts, system logic, technology, physics, component assemblies, and operations classes. The Zachman Framework is better described by a taxonomy for organising architectural artefacts (e.g. By visiting our website, you agree to the use of cookies as described in our Cookie Policy.
