The automotive industry, recognized for its technological advancement, faces challenges in maintaining product quality due to increasing variability in customer preferences, a dynamic competitive environment, and shorter product life cycles. A critical issue is the quality of components supplied by partners, which can be compromised when tools used in production exceed their lifespan. This study addresses the complexities of managing tool life across a vast supplier network, emphasizing the need for enhanced quality control measures that extend beyond the manufacturing plant. Through a case study methodology, this research focuses on developing a low-cost, SAP-based system to monitor and control the lifespan of critical tools used by suppliers. The system aims to proactively prevent defects by issuing early warnings before tools reach the end of their useful life. The study highlights key challenges, including disorganized documentation, outdated SAP systems, and the lack of quantitative data on quality issues. By integrating data from various sources, the proposed solution seeks to improve the quality performance of an automotive company and its suppliers, thereby ensuring product integrity and strengthening customer trust. The findings contribute to the ongoing discourse on supply chain quality management, offering insights into the effective extension of quality control to the supplier level.
