TOGAF iteration cycles run as a loop, not a one-way line
The ADM runs as four iteration cycles that pass work round a ring: Capability frames Development, Development feeds Transition Planning, planning is held by Governance, and Governance reopens the next round. The planner picks how many phases run inside each cycle.
Iteration is the point of the ADM. Capability, Development, Transition Planning and Governance are cycles you revisit, not stages you finish. Drop the closing edge and the architecture is a one-off document that ages the day it ships.
