Abstract:

This paper addresses the inherent difficulties of Large-Scale Software Development projects with respect to producing valid specifications and rigorous acceptance test data. The techniques presented here use the information provided by data flow diagrams DFDs to develop a mathematically precise model which identifies and quantifies the complexity of the processes within a system. This in turn will provide an accurate validation of the specifications against user requirements as well as the information from which acceptance tests can be derived. Author
