Summary
Use Case Analysis provides an initial, high-level definition of how internal elements interact in order to satisfy the system's functional requirements and how they relate to each other statically. This is a fundamental activity on the way to design and development.
Use Case Analysis is supported via sequence diagrams. Instead of showing the interaction between actors and a monolithic system, the system is split into analysis level objects. The responsibilities of the system are divided among the analysis level objects, which are referred to as boundary, control, and entity objects, to achieve a finer grained sequence diagram.
