LEAN MANUFACTURING IMPLEMENTATION THROUGH DMAIC APPROACH: A CASE STUDY IN THE GLASS TRANSFORMATION COMPANY

Manufacturing companies are constantly driven to minimize costs, maximize efficiency, and enhance production quality, as these factors are pivotal for maintaining a competitive edge in the market. Lean manufacturing is a pivotal strategy that plays a crucial role in assisting companies for achieving significant continuous improvement in performance through the elimination of all wastes of resources and time in the total business process. The main objective of this paper is to validate the results of implementing Lean manufacturing through the DMAIC concept. This study focuses on a case study conducted in a glass transformation company that aims to improve the flow within the production workshop by implementing pull systems and minimizing waste. To achieve this objective, a comprehensive literature review was conducted to examine different frameworks for applying the Lean method. The implementation of DMAIC has provided a better structure for the entire project, enabling the selection of appropriate improvement solutions and the use of the right Lean tools. This approach offers several advantages that are not present in other frameworks. The results of this implementation have shown a significant improvement in production planning, flow efficiency, and a substantial financial gain for the company.
