It is valuable to understand a collection of capabilities within the enterprise. One part refers to the capability of the enterprise to develop and consume the architecture. The second part refers to the baseline and target capability level of the enterprise. Gaps identified in the Architecture Capability require iteration between Architecture Vision and Preliminary Phase to ensure that the Architecture Capability is suitable to address the scope of the architecture project (see Part III, 19. Applying Iteration to the ADM). Gaps, or limitations, identified in the enterprise's capability to execute on change will inform the architect on the description of the Target Architecture and on the Implementation and Migration Plan (see Part IV, 36.2.14 Implementation and Migration Plan) created in Phase E and Phase F. This step seeks to understand the capabilities and desires of the enterprise at an appropriate level of abstraction (see 20. Applying the ADM across the Architecture Landscape). Consideration of the gap between the baseline and target capability of the enterprise is critical. Showing the baseline and target capabilities within the context of the overall enterprise can be supported by creating Value Chain diagrams that show the linkage of related capabilities. The results of the assessment are documented in a Capability Assessment (see Part IV, 36.2.10 Capability Assessment).
