BACKGROUND: One of the main steps of the B-BS protocol is feedback delivery. Although the effectiveness of feedback in improving performances is widely supported, there are only a few studies regarding the importance of timing in feedback delivery processes. AIMS: The purpose of this thesis was to evaluate whether the temporal placement of feedback affected safety workers’ performances in a manufactural factory and compare the effectiveness of different temporal locations of feedback. METHOD: Operational lines and warehouses of 2 different plants of Mitsubishi located in Pavia (Italy) were subjected to immediate feedback (post performance) or delayed feedback (during the weekly safety meeting). RESULTS: The results showed that both immediate and delayed feedback increased the percentage of safe performances carried out by workers. However, weekly feedback was more effective as it led to a higher number of safe operations than immediate feedback and in a shorter time.
CONTESTO Una delle tappe principali del protocollo B-BS è l’erogazione del feedback. Nonostante l’efficacia del feedback nell’ incrementare le performance di sicurezza sia ampiamente riconosciuta, in letteratura sono presenti pochi studi in merito a quale sia la tempistica di erogazione migliore. SCOPO L’obiettivo di questa tesi è stato valutare se la collocazione temporale del feedback sia in grado di modificare i comportamenti degli operatori in una industria manifatturiera e comparare l’efficacia tra feedback immediato e differito. METODO Le linee operative e i magazzini degli stabilimenti della sede Mitsubishi di Pavia sono stati sottoposti a feedback immediato, dopo il comportamento osservato, o differito, erogato dai Safety Leader in occasione delle riunioni settimanali di sicurezza. RISULTATI I risultati hanno evidenziato che sia il feedback immediato che il feedback differito sono in grado di aumentare la percentuale di comportamenti sicuri esibiti dai lavoratori.Tuttavia, il feedback differito si è rivelato più efficace perchè ha portato ad un aumento di comportamenti sicuri in un arco di tempo minore.
L'effetto del feedback immediato e differito sull'aumento dei comportamenti sicuri in una realtà industriale manifatturiera
