Lean Manufacturing (LM) practices have gained popularity as a means to achieve high-quality products while reducing costs and delivery times. However, the implementation of LM can be challenging, with a high failure rate. This paper aims to explore the perspectives of employees and managers on LM practices implemented in an automotive company. The research involved primary and secondary data analysis, combining observation, interviews, and a questionnaire survey. The survey assessed knowledge and skills, impact on quality improvement, motivation, supervisor support, control, and engagement in LM development. The results highlight the importance of management commitment and support in achieving successful LM implementation. Moreover, the study emphasises the positive impact of LM practices on employee motivation and the overall quality of processes and products. The PDCA cycle emerged as the most impactful tool, along with other recognised tools like Poka Yoke, Andon, Kaizen, Visual Management, and the 5S method. The findings contribute to understanding the implementation and effects of LM practices, providing insights for companies seeking improvement through Lean Manufacturing methodologies.
