<p>The objective of this work was to reduce costs associated with the quality of an avocado production company in the province of Virú in Peru. We began by diagnosing the production area of the company, and the identified causes were the lack of training for harvest personnel, lack of training for machine operators, shortage of personnel due to overproduction, and lack of nutrients during the production period. The indicators for each cause were analyzed using statistical control and quality management tools. Tools such as Quality Function Deployment (QFD) with its Quality House, Failure Mode and Effects Analysis (FMEA), and the DMAIC Six Sigma methodology were used to reduce costs. At the end of the research, the results were positive, with a reduction in monetary losses associated with each root cause and an improvement in the statistical behavior of the investigated indicators. The Z-Score increased in each of the 4 indicators. The initial loss was $112,771.04, and the improved loss was $49,401.16, resulting in a benefit of $63,369.88.</p>
