With an electoral roll of 850,000 voters that is ethnically diverse and a complex electoral geography due to a high percentage of mountainous area, its implementation is very valuable for a comparative analysis. The gradual implementation allowed for a systematic assessment, conducted by a large survey of voters and poll workers, who had used both voting methods (the traditional one and the new voting system). This paper presents this case study, emphasizing the goals pursued by this reform as well as some findings from this large undertaking. It concludes by documenting the lessons learned and examining the challenges ahead.enText/Conference Paper1617-5468
