Show activity on this post. <<extend>> use cases are used when you want to provide point in a use case where you can later add new functionality, and not to show optional operations. Any use case can be optional, they only show functionality that the system provides to the user and do not show ordering or causality. A use case represents a user goal that can be achieved by accessing the system or software application. In Visual Paradigm, you can make use of the sub-diagram feature to describe the interaction between user and system within a use case by creating a sub-sequence diagram under a use case.You can also describe the use case scenario using the Flow of Events editor.
