Managing Requirements for E-Voting Systems: Issues and Approaches

This paper discusses our approach and experiences on structuring and maintaining requirements for an e-voting system we have built and deployed for elections. Issues related to integrating laws and recommendation for e-voting systems, managing different elections and configurations, supporting a spiral development, yielded problems and approaches to help maintain integrity of requirements and a coherent view of the system. Moreover, the relationship between requirements and system architecture is based on finite state machines, that bridge the gap between the laws and the actual behavior of the machine.
