Sažetak
Quality control is central to any manufacturing company. From the manufacturer's point of view, quality is related to technological design and the making of the finished product the purpose of which is to meet the consumer's needs. From the consumer's perspective, quality is often related to value, usefulness, price or the time within which a product or service can be supplied. Each quality control process can be improved in the course of time in order to enhance its quality as well. In the global market, with all the uncertainties and fierce competition, companies need to change and adjust their business strategies very fast in order to meet the customers' preferences. Faced with educated customers and new competitors, manufacturing companies have to continuously consider their methods of production and change them if they want to make sure they will survive in the market. A very efficient way to continuously improve business processes is the application of the Six Sigma methodology. The Six Sigma methodology is a business strategy as well as a quality control methodology, which represents the application of formalized systems with the purpose of achieving maximum customer satisfaction at minimum total cost. This paper is based on the hypothesis that the application of the Six Sigma methodology can improve the existing quality of finished products and reduce quality control costs. The hypothesis has been tested in a company competing in the highly competitive global market for motor vehicle spare parts. Due to the application of the DMADV approach, the brake discs manufacturer managed to accelerate the process of final control of finished products by 35%, and reduce quality control costs by 50%. The entire quality control process was analyzed using the project approach, and in five stages of the DMADV approach a new automated plant for quality control of finished products was designed and set up. Control automation has removed the need for manual labour, and productivity has risen by 48%. The new quality control process is resistant to internal variability and is to a high degree tied to consumers' demands.
