%T Incorporating Use\-Case Analysis in PCSC Method %A Chandran Elamvazuthi, Gordon A. Manson %E Patrick Nixon %B Proceedings of WoTUG\-18: Transputer and occam Developments %X Use\-case analysis is a simple but useful technique for driving the process of analysis in a meaningful manner. It is used, in one form or another, in various object\-orientated software development methods notably OOSE, Booch and OMT. In this paper, we explain how use\-case analysis has been incorporated into PCSC, a method based on the occam model for developing parallel software systems. To illustrate the usage of use\-case analysis in PCSC, we present a simple case study of a Character Sorting System.
