ArchiMate — Migration: Plateaus, Gaps and Work Packages
The implementation and migration layer, which answers the question a landscape diagram cannot: what changes between here and there, and in what order. Plateaus are the stable states, a gap names the difference between two of them, and work packages deliver the things that close it.
Make it your own.
