This contribution discusses the challenge to put research findings into practice in the field of crime prevention, namely to safeguard the integrity of public contracts. In 2008, Transcrime developed a risk-assessment model to support law enforcement against organized crime (OC). The aim was to provide a tool for highlighting the public contracts, which, according to different criteria, showed a higher risk of infiltration by OC. This chapter presents the model, its advantages, its limitations, and the issues related to its possible implementation. It concludes that, although this pioneer attempt did not succeed, this experience helped to develop further research in the field. In the meantime, the public administration progressively acknowledged the approach of risk management as a valuable tool for preventing crime.
