Phase E, Opportunities and Solutions, is the specific phase within the TOGAF Architecture Development Method (ADM) where the gaps identified in the preceding architecture development phases (B, C, and D) are consolidated. During this phase, potential solutions are identified, and the necessary changes are grouped into logical work packages. This process forms the basis of the initial Implementation and Migration Plan and the Architecture Roadmap, directly associating the identified architectural gaps with the work required to address them.

A. Phases G and H: These phases occur after work packages are defined. Phase G governs the implementation of the work packages, and Phase H manages changes to the architecture post-implementation.

B. Phase F: Phase F, Migration Planning, finalizes the detailed Implementation and Migration Plan and prioritizes the work packages that were initially created and grouped in Phase E.

C. Phases B, C, and D: These are the core architecture development phases where gap analysis is performed to identify the differences between the Baseline and Target Architectures, not to group them into work packages.

Section 8.3

Phase E: Steps: Step 5 explicitly states

"Consolidate the gaps

solutions

and dependencies from Phases B

C

and D

and group the migration actions into work packages." This directly confirms that the association of gaps to work packages is a primary activity of Phase E.

Section 8.4

Phase E: Outputs: The "Implementation and Migration Plan" is a key output of Phase E. The description of this plan includes the "Work package portfolio

" which is the result of the grouping activity.

Gap Analysis: This section describes gap analysis as a technique used primarily in Phases B

D

and E. It notes that while gaps are identified in B

C

and D

they are consolidated in Phase E to form the basis for the Implementation and Migration Plan

which is structured around work packages.
