Identify Architecture Roadmap components by looking at gap between baseline and target business architectures
Approach
General - Business Architecture is prerequisite to other architectures
Developing the Baseline Description - Use existing architecture documentation. Can include missing capabilities, new value streams, etc.
Applying Business Capabilities - Map capabilities to orgs, value streams, IT, etc. Relationship maps and heat maps are common tools.
Applying Value Streams - Offer context into why capabilities are needed
Applying the Organization Map - Relationship between key orgs. Provides org context for the EA effort.
Applying Modeling Techniques - Can use various models like: activity models, use-case models, class models, etc. Provide insight into how the org operates.
Architecture Repository - Consider resources from the repository
