Architecture process framework	A description of a process that develops a target architecture to meet some requirements, under some constraints, plans the move from the baseline state to the target state, and governs that change.
Architecture State	A baseline architecture describes a system in a state, perhaps operational, ready to be reviewed and/or revised. A target architecture describes a system in a state that is to be created and implemented in the future. An intermediate or transitional architecture defines a state of a system between baseline and target.
The Open Group Architecture Framework (TOGAF)	A well-known framework for enterprise architecture, centred on a process called the architecture development method (ADM).
Avancier Methodology (AM)	An architecture process framework designed more for solution architecture than enterprise architecture. The process is presented in 9 phases, though iteration and parallelism is expected. 1 Define precursors 2 Scope the work 3 Understand the baseline 4 Review non-functional criteria 5 Outline the target 6 Select and manage suppliers 7 Plan the migration 8 Hand over 9 Govern the migration.
