This research aims to identify how to measure the level of success of a Public Private Partnership (PPP) projects using case
studies along Europe. The analysis is based on a Performance Measurement System (PMS) using a step-by-step approach.
Altogether 13 PPP road projects in the EU have been chosen to test the PMS. Two measurement approaches have been used to
analyse the performance of these case studies. Herein, altogether 29 performance measures (PMs) and 9 key performance
indicators (KPIs) that have been developed systematically have been considered. The first approach used has evaluated the
number of successful and failure performance measures in order to show different level of success in projects. In this approach,
the weighting used for the performance measures are considered equal. The second approach has been then used to weight the
PMs using a Delphi analysis first, and then to evaluate overall performance. The comparison of the results reveal that there are
dominant PMs and KPIs that determine the success of a project. The results illustrate how PPP projects may be evaluated to
extract conclusions about the success/failure of a project from a global view, showing the areas and elements that need to be
considered along this process.
