4.2. Use of Scenarios for evaluation of Business Drivers and Quality Attributes
From the elicited requirements, the most important business drivers of national e-voting in
South Africa are the need to (i) reduce the huge cost associated with the use of ballot papers, and the
distribution of electoral materials; (ii) increase the transparency of the electoral process; (iii) have a faster
procedure for e
fficient voting and counting; (iv) have credible results; (v) increase voters’ accessibility;
(vi) minimise carbon footprint; (vii) reduce the costs expended on elections; and (viii) increase
participation of voters. The panel of experts considered the attributes of security, performance, and
functional suitability as deserving of the highest priority because of the identified core business drivers.
Security deals with the ability of the system to mitigate threats that may be harmful to its operations,
performance is concerned with the speed and accuracy of system operations, while functional suitability
is assessed based on the level of auditability, availability, transparency, and verifiability of the system.
We derived specific scenarios to assess these important attributes (see Table
3
).
