SysML requirement diagrams: Banking transactional platform case study

Abstract

The aim of this paper is an investigation into the practicality of SysML Requirement Diagrams in requirement identification and specification for an Internet banking transactional platform. The research attempts to discover if SysML Requirement Diagrams can be applied not only for defining requirements in engineering domains, but also for conducting business cases. The paper is structured as follows: after the Introduction, the prerequisites of requirement specification in SysML are clarified in Section 2. Section 3 exemplifies the containment relationships in a banking transactional platform case study. A Requirement Diagram of a Money Transfer Service in both graphical and tabular form is developed and explained in Section 4, followed by Conclusions. The study has generated demand for more in-depth analysis of business requirements specification using other functionally related SysML/UML diagrams. © 2011 Springer-Verlag Berlin Heidelberg.
