capability granularity

The quantity of functionality encapsulated by a specific service capability determines the level of corresponding capability granularity. For example, a Get capability that retrieves an entire business document may be considered coarse-grained, whereas a GetHeader capability that only retrieves a subset of the business document is more fine-grained.

Regardless of the overall level of service granularity, a service can contain a combination of fine and coarse-grained capabilities.

Capability granularity represents one of four types of design granularity, the other three being service, data, and constraint granularity. Each of these granularity types is affected differently by the application of service-orientation design principles.
