Abstract

This article aims to present the impact of the use of quality tools in reducing claims and losses in a large yogurt company in the state of Paraná. The study demonstrates the practical application of quality tools such as PDCA Cycle, Brainstorming, Pareto, hypothesis testing, graph Ishikawa, Benchmarking and 5W2H implemented by multidisciplinary teams, with the goal of identifying deviations and opportunities for process improvement. Through the proposed work, focused on the process with greater opportunities to gain line, we observed the application of PDCA cycle for the creation and maintenance of a cycle of continuous improvement in the process, which, aided by tools such as Pareto, test hypothesis and graph Ishikawa, directing the research enabled the stabilization and meeting the targets proposed in th e defined line. At the end of the work were clear advantages of structured implementation of quality tools and systematization of actions directed at the causes of deviations identified, a view that there were significant reductions of 41% in the number of complaints and 73% in the number of losses. The methodology applied proved to be effective and capable of extension to other production lines.
