Negli ultimi decenni, studi e ricerche hanno sostenuto l’importanza economica degli investimenti in OHS (Operational Health and Safety), tuttavia, applicazioni pratiche di questi studi hanno documentato come sia aleatorio e contenuto il risultato di investimenti in sicurezza. Questo fenomeno ha portato le piccole medie imprese a prediligere interventi con ritorni superiori e facilmente prevedibili, nella fattispecie investimenti legati alla produttività. Questa ricerca intende colmare il divario tra studi scientifici e implementazioni pratiche, sviluppando un nuovo strumento per l’analisi e lo sfruttamento delle interdipendenze tra OHS e produttività, al fine di ottenere una stima più accurata dei benefici degli interventi di sicurezza sul lavoro. Lo strumento si concentra sulle sinergie ed i trade-off tra le due dimensioni (OHS e produttività) e, in seguito ad una stima quantitativa e semi-quantitativa degli effetti, è in grado di supportare il management con un processo più efficacie di intervention design. Lo studio richiede un approccio multidisciplinare al fine di gestire interventi misurati in dimensioni diverse. In particolare, la ricerca è basata sulla analisi di molteplici fonti e casi di studio e ha portato alla creazione di un innovativo framework per la analisi integrata e lo sviluppo di nuovi interventi. Le fasi principali dello studio sono l’analisi degli indicatori di performance attiva (Leading KPI) e di performance passiva (Lagging KPI), in quanto permettono di definire accuratamente le interdipendenze trai diversi fattori. Infatti, le relazioni tra OHS e produttività richiedono uno studio integrato dell’intero processo. Infine, per validare la ricerca, sono stati condotti diversi casi di studio e il framework è stato presentato ed analizzato presso una azienda internazionale.

Abstract
In the last years, studies and researches asserted the economic value of OHS (Operational Health and Safety) investments, however real life applications, as well as independent studies, proved that the expected return of safety interventions is hardly ever predictable or comparable with productivity related investments. This phenomenon led small-medium companies to favour other higher returning interventions. This research intends to fill the gap between literature and companies, developing a tool for analysing and exploiting the relationships between operational health and safety and productivity, in order to achieve a more accurate estimation of the overall return. The tool addresses the trade-off and synergies between the two dimensions (OHS and productivity) and after a quantitative and semi-quantitative effects estimation, is able to support the management with a more effective process design. The study requires a multidisciplinary approach in order to couple and compare interventions measured in different ways. In particular, the research was built on multiple sources and case studies, and led to the development of an innovative and comprehensive evaluation and design framework. The core steps of the framework are the division and analysis of leading performance indicators and lagging performance indicators, resulting in a more accurate definition of the interdependences between factors. Indeed the relationships between OHS and productivity dimensions require a new integrated evaluation process. Finally, to validate the tool, the framework was applied to many case studies and proposed to an international company, providing and extensive test to the new tool.File | Dimensione | Formato | |
