TOGAF Practice Exam 2025 – The All-in-One Guide to Master The Open Group Architecture Framework!

The TOGAF ADM (Architecture Development Method) model is categorized as a prescriptive model because it provides a structured approach and detailed guidelines for developing an enterprise architecture. This method outlines phases, deliverables, and key activities that organizations should follow to establish, implement, and maintain an architecture framework effectively.

As a prescriptive model, TOGAF ADM aids architects and stakeholders by offering a clear roadmap for architecture development, emphasizing best practices and standardized approaches that lead to successful outcomes. The prescriptive nature ensures that the focus remains on providing actionable steps and methodologies that can be consistently applied across various projects and organizations. This is particularly valuable for achieving alignment between business needs and IT capabilities.

While descriptive models provide an overview or representation of a process without specific guidance, normative models set standards or benchmarks to be followed—TOGAF ADM does not fit either of these categories. Informal models, on the other hand, lack the structured methodology and detailed processes that TOGAF ADM offers. Hence, the categorization as a prescriptive model underscores its role in guiding organizations in a systematic and repeatable manner through the complexities of enterprise architecture development.
