Maintaining a strong market position is a significant challenge for manufacturing companies, requiring them to meet customer demands through high-quality products while balancing the associated costs. Proper quality management is essential but incurs substantial costs, particularly in terms of production maintenance and prevention. This paper explores the relationship between quality costs and business growth, emphasizing the need for manufacturers to constantly evaluate financial performance in relation to unit production costs and quality maintenance expenses. The study highlights that integrating quality into the production process is a key strategy for preventing business growth inhibition due to escalating quality costs. While investing in quality management can drive business development by improving product quality, customer satisfaction, and operational efficiency, poor management of quality costs can hinder profitability and growth. The findings suggest that strategic handling of quality costs can foster sustainable growth, whereas mismanagement may lead to competitive disadvantages.
The increasing demands for product quality and production efficiency in the plastics industry necessitate the use of structured quality management tools. This study aims to identify critical defects in the production of water bottles using the Pareto-Lorenz analysis and Failure Mode and Effect Analysis (FMEA). The research was conducted in a company specializing in bottle manufacturing, where production incon sistencies were analyzed based on quality control reports. The Pareto-Lorenz method revealed that the majority of defects were attributed to issues related to material injection and assembly oversight. The FMEA analysis prioritized defects based on their severity, occurrence proba bility, and detection difficulty, assigning Risk Priority Numbers (RPN) to facilitate targeted corrective actions. Implemented solutions, such as enhanced quality control procedures and systematic employee training, resulted in a significant reduction in defect occurrence and improved production efficiency. The study confirms that combining FMEA and Pareto-Lorenz analysis is an effective approach for optimizing quality management in industrial settings, offering practical insights for manufacturers seeking to enhance product reliability and competitiveness.
