7. Migration Efforts Domain Identities
Data Inputs & Outputs A datum is an element of information that is transferred from an connector, or received by a service, via a connector.
Services A service is an abstract unit of software instructions and internal state that provides a transformation of data via its connector.
Interfaces An connector is an abstract mechanism that mediates communication, coordination, or cooperation among services.
Technical Dependencies A dependency is a immutable condition that mandates cohesion to external hardware or software or embedding in an environment or other domain.

8. Migration Efforts
Domain Identities Technical dependencies are further split into divided domains unless the effort to split the domain dependency out weighs the cost to maintain the dependency.

9. Migration Efforts Distributed System Interfaces
Split the code base into multiple executables
Decouple the message data
Relax the binding between development teams
Publish “client code” executables

10. Migration Efforts Unified Version Control
Formalize the code base into code sets based upon the identified domains
Automate all code set build and deploy procedures
Includes database schemas
Includes run-time, work station, server and client environments

11. Migration Efforts Synthesize the business
Architect a business model not the features
Abstract out data dependencies not switch statements
Abstract out hierarchical dependencies not crusty concrete inheritances
Design the framework not the details of how it is implemented
Design unanimously not a methodology campaign

12. Migration Efforts Teamwork and Focus Team meetings Unified effort
