This document provides a summary of core concepts from the TOGAF Foundation chapter 2. It discusses categorization systems used to organize architecture building blocks and solutions. It also describes the Architecture Development Method (ADM) phases and iterations for developing architectures. Finally, it introduces architecture models which represent stakeholder views and concerns through different views and viewpoints. The document emphasizes that the TOGAF framework provides a repeatable process to build reference models and maturity of enterprise architecture over time.
