The constant focus on improving production processes and the supply chain is an essential factor in the success of any company. In an industry like the automotive sector, better resource management can make a significant difference. This thesis analyzes the current material management model related to seating production at Lear Corporation's Caivano plant and defines precisely a Kanban system for the procurement of specific components. The project aims to transform the procurement model, which is based on push logic, into a pull model, which can respond dynamically to actual production demand. The thesis adopts a DMAIC (Define, Measure, Analyze, Improve, Control) approach for the implementation.
