Prioritizing Product Quality Problems Using Quality Management Tools

Abstract In today’s competitive business environment, effectively analyzing, evaluating, and resolving product quality problems is critical to maintaining customer satisfaction, reducing financial losses, and preserving a company’s reputation. This study prioritizes internal and external quality problems in paperboard packaging using selected quality management tools. Product quality problems are categorized based on their frequency of occurrence and financial losses. Three quality management tools are used: the Pareto-Lorenz diagram, the matrix data analysis diagram, and the box plot. The Pareto-Lorenz diagram identified the key quality problems that generate the highest number of events and the greatest financial losses, consistent with the 80/20 rule. The matrix data analysis diagram divided the quality problems into four groups based on their combined impact, indicating critical problems for both categories. The box plot identified outliers and extremes, revealing quality problems with significantly higher frequency and financial impact than others. All quality tools used identified the overprint complaint with code 403 as critical. The results highlight the effectiveness of the quality management tools used in prioritizing product quality problems.
