Esta dissertação teve como objetivo a aplicação de metodologias Lean numa oficina de manutenção automóvel, com o intuito de melhorar processos e reduzir desperdícios. O estudo foi realizado na Carclasse Lisboa, onde se analisou o fluxo de trabalho e se identificaram oportunidades de melhoria. Através da observação direta e da análise de dados foi possível propor soluções baseadas em ferramentas Lean, tais como a gestão visual e padronização de processos. Com base na análise foram propostas várias melhorias, entre as quais o desenvolvimento de uma ferramenta de gestão de estacionamento, que visa melhorar a alocação das viaturas de acordo com o tipo de serviço e a duração das reparações. A ferramenta facilita a organização dos veículos, atribuindo lugares mais próximos ou distantes consoante a complexidade do trabalho, reduzindo assim o tempo de movimentação. Apesar de não ter sido possível implementar todas as soluções propostas durante o período do estudo, devido a um curto tempo para a aplicação das mesmas, as análises indicam um elevado potencial para a redução de desperdícios e a melhoria do desempenho operacional. O estudo também destaca os desafios de implementação em empresas com técnicos experientes, que podem resistir a mudanças nos processos estabelecidos. Conclui-se que a adoção de uma cultura de melhoria contínua e a implementação das metodologias Lean poderão trazer benefícios significativos às empresas, com impacto direto na produtividade e na satisfação dos clientes.
Abstract The aim of this dissertation was to apply Lean methodologies in a car maintenance workshop in order to improve processes and reduce waste. The study was carried out at Carclasse Lisboa, where the workflow was analysed and opportunities for improvement were identified. Through direct observation and data analysis, it was possible to propose solutions based on Lean tools such as visual management and process standardisation. Based on the analysis, several improvements were proposed, including the development of a parking management tool, which aims to improve the allocation of vehicles according to the type of service and the duration of repairs. The tool makes it easier to organise vehicles, assigning spaces closer together or further apart depending on the complexity of the job, thus reducing movement time. Although it was not possible to implement the proposed solutions during the study period, the analyses indicate a high potential for reducing waste and improving operational performance. The study also highlights the challenges of implementation in companies with experienced technicians, who may resist changes to established processes. It concludes that adopting a culture of continuous improvement and implementing Lean methodologies could bring significant benefits to companies, with a direct impact on productivity and customer satisfaction.
