TOGAF - Architecture Development Method (ADM)

Architecture Development Method (ADM)

The TOGAF ADM provides a tested and repeatable process for developing architectures. The ADM includes establishing an architecture framework, developing architecture content, transitioning, and governing the realization of architectures.

All of these activities are carried out within an iterative cycle of continuous architecture definition snd realization that allows organisations to transform their enterprises in a controlled manner in response to business goals and opportunities.
