What part of the TOGAF document provides a number of architecture development phases, together with narratives for each phase?

The Architecture Development Method (ADM) is a central component of TOGAF and focuses specifically on the processes required to develop and manage the architecture within an organization. It outlines a structured approach, divided into distinct phases, which guides practitioners through the architecture development lifecycle. Each phase is described in detail, including specific activities, deliverables, and outcomes expected during that phase.

This comprehensive narrative helps architects understand how to approach their work pragmatically, thereby facilitating structured and repeatable architecture development processes. By following the phases outlined in the ADM, organizations can ensure that their architecture aligns with business goals and effectively addresses stakeholder needs.

The other sections of the TOGAF document serve different purposes. The Introduction provides a broad overview of the framework but lacks the detailed, phase-specific content found in the ADM. The ADM Guidelines and Techniques section supplements the ADM by offering tips and recommendations for implementation, while the Architecture Content Framework establishes a structure for the deliverables produced during architecture development but does not detail the phases.
