The TOGAF ADM is an iterative cycle of eight phases The method turns as a ring, but it is iterative, not a single pass: you iterate within a phase, loop back between phases, and repeat the whole cycle, re-entering at the phase that fits rather than restarting at A. Requirements Management is two-way with every phase.
The TOGAF ADM is an iterative cycle of eight phases
The TOGAF architecture development method as a ring of eight phase panels around a central Requirements Management hub. A Preliminary Phase panel enters at Phase A, Vision, then clockwise arcs run through B Business, C Information systems, D Technology, E Opportunities and Solutions, F Migration planning, G Implementation governance and H Architecture Change Management, closing back to A. The method is iterative, not a single pass, and two-way spokes join the hub to every phase.
A Vision The Architecture Vision and remit
B Business The business architecture
C Information systems Data and application architecture
D Technology The technology architecture
E Opportunities and Solutions Solution options and work packages
F Migration planning The implementation and migration plan
G Implementation governance Delivery held to the architecture
H Architecture Change Management Keeping the live architecture current

Preliminary Phase Principles and the architecture capability
TOGAF applies the ADM iteratively through four overlapping cycles, not as a single pass:
Context (Preliminary and A) · Definition (B to D) · Transition Planning (E and F) · Governance (G and H)
