Poster 4 of the TOGAF ADM Cycle Poster Series provides an overview of the common elements of Phases B, C & D. 

Phase B deals with the Business Architecture, developing a Target Business Architecture that shows how the enterprise can achieve the Architecture Vision, and makes a first-cut at identifying candidate Architecture Roadmap components.

Phase C takes these business perspectives as a starting point for describing the Information Systems Architectures, while phase D develops the Technology Architecture for the architecture project.
