Application of Quality Tools in Solving a Production Problem

Abstract

The article focuses on the issue of automotive products. The product is a component necessary for the proper functioning of the engine in a car. The application of various quality tools represents the identification and subsequent elimination of defects to improve the manufacturing process. The aim was to reduce the proportion of complaints related to product malfunction and to increase the overall control of the manufacturing process. This includes activities such as identification, analysis, and elimination of the root cause of the claimed product function. Standard tools used to identify and analyse the root cause of the problem such as Ishikawa, Pareto, 4Wh1 were used. It usually focuses on inventory reduction, machine optimization, process synchronization. In addition to basic quality tools, process capability or microscopic analyses were also used. The system quality management tool of auditing was also used. The root cause of the problem was identified. Measures were subsequently taken and savings of more than EUR 50,000 were achieved.
