Abstract

Use Case Maps (UCMs) are a technique used to capture functional requirements and high level designs of complex systems composed of many features. Once you have chosen UCMs as part of your software development process, the question arises as how to most effectively use UCMs. This paper introduces patterns which provide guidance in selecting one of three major UCM styles depending on your software development context. The Individual Maps UCM style is most useful for rapidly and independently capturing a few key features of your system, features being optional or incremental units of functionality. The Standard Root Map UCM style is most appropriate if a small, evolving system consisting of interacting features needs to be documented. The Isolation and Integration UCM style is best applied to large, evolving systems with many interacting features.
