Solution Services can be grouped into manageable, domain-specific service inventories, each of which can be independently standardized, governed, and owned. Application Inventory domain boundaries need to be carefully established. Impacts Standardization disparity between domain service inventories imposes transformation requirements and reduces the overall benefit potential of the SOA adoption. Principles Standardized Service Contract, Service Abstraction, Service Composability Architecture Enterprise, Inventory   An enterprise partitioned into domain service inventories, each representing a pre-defined domain.
