Use case driven structured analysis

Structured analysis is a widely used system modeling technique for understanding real world systems before they are built. It is based on functional decomposition of the problem domain. However, its inherent weakness is in identification and partitioning of a system's functionality. This paper proposes a use case driven approach to structured analysis. This approach makes it easier for model builders to find the functionality of a system and its partitioning it also matches well with structured analysis as it is top-down approach like the structured analysis. The approach is presented along with an example of its application.
