This study examines the implementation of an error catalogue as an innovative tool within the quality management framework of a manufacturing organization. The motive behind the research lies in addressing the critical need for effective quality management strategies that can systematically reduce defects and enhance customer satisfaction. Existing literature highlights the importance of quality management; however, there is a noted scarcity of studies focusing specifically on the practical application and impact of error catalogues within diverse organizational contexts. The methodology employed in this research involved a case study approach, where quantitative data—such as defect rates and customer complaints—were collected pre- and post-implementation of the error catalogue, complemented by qualitative assessments of employee engagement through interviews and surveys. Findings indicate a reduction in defects and a decrease in customer complaints within six months post-implementation. Additionally, the error catalogue fostered a culture of continuous improvement, empowering employees to actively participate in error identification and remediation processes. This underscores the value of systematic error management as a means to achieve quality excellence. By providing insights into both quantitative and qualitative improvements associated with the implementation of an error catalogue, this study contributes to the literature on quality management tools and offers practical implications for organizations seeking to enhance their quality assurance practices.
