Our Cases with Use Cases

This paper presents our experiences of using use cases in real software projects. The projects, which deal with the development of various network management systems, multimedia platforms, and other such software, have been run at Nokia Telecommunications. All these projects have adopted our OMT-based object-oriented approach, which we call OMT++. First the paper shortly describes the OMT++ approach and how use cases fit into the method.
