This study presents the findings of the x-index – a public procurement benchmarking tool – which measures and evaluates the performance of municipalities in public procurement and compares it with best practices. The findings are grouped into three categories, based on the size of the municipalities to provide an objective representation. x-index is based on a statistical model containing 9 sub-indexes, each of which assesses several dimensions of public procurement, and which jointly focus on the areas of transparency, competition, and efficiency. The x-index includes all 38 municipalities of Kosovo and covers their procurement activities in the period January- December 2018, consisting of 2649 contract award notices, in total worth over €179 million. The index is constructed based on objective criteria. Data for the construction of the index were obtained from the official e-procurement platform and other official statistics.
