Description

The S4 Service Functions view defines the behavior of a service in terms of the functions it is expected to perform. S4 is the key behavioral specification for services. Equivalent in nature to L4 - Logical Activities and R4 - Resource Functions, it specifies a set of functions that a service implementation is expected to perform.

Implementation

The S4 view can be represented using:

  • A S4 Service Functions Taxonomy diagram based on the UML Clas diagram.
