2.4 Architecture Development Method The TOGAF Architecture Development Method (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. 4.1 ADM Overview The TOGAF ADM is the result of continuous contributions from a large number of architecture practitioners. It describes a method for developing and managing the lifecycle of an Enterprise Architecture, and forms the core of the TOGAF standard. • ADM is applied *Iteratively* throughout the *entire process*, *between phases*, and *within them*. • there should be *frequent validation of results* against the *original requirements*. • Each phase has *Inputs* amd *Outputs*. • The phases of the ADM cycle are *divided into steps* inside the phase.
