This thesis focuses on Continuous Improvement as a management system capable of driving Operational Excellence in an industrial context. The aim of this thesis is to analyse the role of a structured and well-defined Continuous Improvement system in achieving sustainable results and ensuring that improvement practices are maintained, embedded, and transferred over time across the organization. The first part presents the theoretical foundations of the study, with particular attention to World Class Manufacturing (WCM), Lean Thinking and its main tools, and Six Sigma methodologies. These approaches are analysed to provide a comprehensive understanding of the Continuous Improvement framework and its practical application within the company selected as a case study operating in the FMCG sector. The thesis then examines the structure of the improvement system proposed by the literature, highlighting the Critical Success and Failure Factors, with particular attention to standards definition and a performance measurement system, with an overview on Cost Deployment. Subsequently, it describes the practical activities carried out within the company to implement and sustain improvement initiatives. Emphasis is placed on the long-term sustainability of the process and on the mechanisms that ensure continuous performance enhancement over time. Throughout the work, theoretical concepts are connected with real examples and experiences, providing a comparison between academic models and industrial practice, as well as a concrete representation of how Continuous Improvement systems can be implemented in a manufacturing environment.
La presente tesi si concentra sul Miglioramento Continuo come sistema di gestione in grado di promuovere l’Eccellenza Operativa in un contesto industriale. L’obiettivo della tesi è analizzare il ruolo di un sistema di Miglioramento Continuo strutturato e ben definito nel raggiungimento di risultati sostenibili e nel garantire che le pratiche di miglioramento siano mantenute, integrate e trasferite nel tempo all’interno dell’organizzazione. La prima parte presenta i fondamenti teorici dello studio, con particolare attenzione al World Class Manufacturing (WCM), al Lean Thinking e ai suoi principali strumenti, nonché alle metodologie Six Sigma. Tali approcci vengono analizzati per fornire una comprensione completa del quadro di riferimento del Miglioramento Continuo e della sua applicazione pratica all’interno dell’azienda selezionata come caso di studio, operante nel settore dei beni di largo consumo (FMCG). La tesi esamina poi la struttura del sistema di miglioramento proposto dalla letteratura, evidenziando i fattori critici di successo e di fallimento, con particolare attenzione alla definizione degli standard e a un sistema di misurazione delle performance, con una panoramica sul Cost Deployment. Successivamente, descrive le attività pratiche svolte all’interno dell’azienda per implementare e sostenere le iniziative di miglioramento. L’accento è posto sulla sostenibilità a lungo termine del processo e sui meccanismi che garantiscono un miglioramento continuo delle prestazioni nel tempo. Nel corso del lavoro, i concetti teorici sono collegati a esempi ed esperienze reali, fornendo un confronto tra modelli accademici e industriale, nonché una rappresentazione concreta di come i sistemi di miglioramento continuo possano essere implementati in un ambiente produttivo.

Abstract
This thesis focuses on Continuous Improvement as a management system capable of driving Operational Excellence in an industrial context. The aim of this thesis is to analyse the role of a structured and well-defined Continuous Improvement system in achieving sustainable results and ensuring that improvement practices are maintained, embedded, and transferred over time across the organization. The first part presents the theoretical foundations of the study, with particular attention to World Class Manufacturing (WCM), Lean Thinking and its main tools, and Six Sigma methodologies. These approaches are analysed to provide a comprehensive understanding of the Continuous Improvement framework and its practical application within the company selected as a case study operating in the FMCG sector. The thesis then examines the structure of the improvement system proposed by the literature, highlighting the Critical Success and Failure Factors, with particular attention to standards definition and a performance measurement system, with an overview on Cost Deployment. Subsequently, it describes the practical activities carried out within the company to implement and sustain improvement initiatives. Emphasis is placed on the long-term sustainability of the process and on the mechanisms that ensure continuous performance enhancement over time. Throughout the work, theoretical concepts are connected with real examples and experiences, providing a comparison between academic models and industrial practice, as well as a concrete representation of how Continuous Improvement systems can be implemented in a manufacturing environment.| File | Dimensione | Formato | |
