Migration strategy roadmaps, driven by strategic business priorities, merge high priority opportunities with associated target architectures.

Many opportunities are identified through simplification programs that reduce the diversity of solutions in any given capability area. These can be process, system and technology standardization programs, all requiring a planned migration approach to achieve the desired level of convergence. The Proact Toolkit provides a migration model that depicts systems and technology migration paths, and the related dependencies.

Implementing new capabilities identifies other opportunities. In either case, it is essential to understand the impact of proposed changes to the enterprise's capabilities. The Toolkit's framework views provide the ability to identify all the critical areas affected by any changes, which makes decision-making more effective and responsible.

Specifically, architects define a set of inter-related target architectures in all four views for each migration stage. This involves determining all inter-dependencies so that any decisions to adjust program mix or manage any slippages in program delivery can be made with full awareness of the impact to other programs. The migration strategy roadmap leads to the formation of programs and related projects that are aligned with the target architectures, for the next stage of migration. Any changes to these target architectures or to the staging of any dependent capability must be reviewed for architectural and business impact. In this way, Enterprise Architecture plays a valuable role in supporting the governance function for the Program Management Office.

The handoff to the Program teams consists of a roadmap, created in the Migration Model, that explains the planned changes in capabilities and the associated solutions over time. A related set of blueprints, in the form of target architectures, is also provided.
