    The low level of quality control in company processes presents a challenging problem when critical aspects of these processes are neglected. In this context, this investigation focuses on analyzing the quality of products manufactured by the company TEXCODI CÍA. LTDA. The research was based on the DMAIC (Define, Measure, Analyze, Implement, Control) methodology, adopting a quantitative approach. Samples were collected during a month in the labs, using systematic random sampling of 20 subgroups with the highest-rented product of the company in question. The investigation determined that the cutting and assembly stages were key points for quality control during the process. It was established that these stages presented critical problems in quality control, corresponding to the reception of inadequate raw materials and the lack of proper equipment maintenance. The study results showed that the critical variables for quality control were: inadequate dimensions (with a 70.5% error rate), and loose threads (with a 53.8% error rate). The quality control metric in the cutting and assembly stages yielded 1.57 and 2.61 sigmas, respectively, which is well below the industry standard of 3 to 4 sigmas. In conclusion, the company lacks a quality control process capable of achieving sigma levels on par with the textile industry. This negatively impacts the quality of their products and results in a loss of credibility, clientele, and competitiveness in the market.
