NPM reforms have become a global trend and performance management systems are considered suitable to enhance the decision-making process and accountability. The aim of the paper is to carry out a comparative study on the adoption of performance measurement tools in Italian and Spanish (medium-sized and large) local governments. It seeks to find out how widespread these tools are and how their usefulness is perceived. The results show differences between the two countries and that the presence of professional managers – experienced with performance measurement tools – positively affects the adoption of these tools. Moreover, performance measurement tools are perceived as a support for accountability purposes.
