    Phytosanitary quality control in export products is fundamental to ensure customer satisfaction and product quality, therefore, this research focused on evaluating the performance of quality control during lot inspection at SISA GREEN FLOWERS. The research applied the DMAIC (Define, Measure, Analyze, Improve and Control) methodology with a quantitative approach to address the quality problem. The problem was defined using Pareto diagrams, brainstorming and flow charts. Measurement developed systematic sampling to generate 135 subgroups to develop control charts of critical variables. The analysis used Ishikawa diagrams and 5W technique. Finally, the proposed improvement seeks to solve the root cause of defective product acceptance. Quality defects were analyzed using critical quality variables (CTQ's). Consequently, the results of the study show that the defect "presence of mites" presents problems with the variable "compliance with phytosanitary protocols for mites" because it showed a level of 0.6291 sigma. The defect "affections by thrips" was evaluated integrally, obtaining 0.7067 sigma. As for defects related to "stem deterioration", the variable "stem appearance" was identified as having a level of 0.7204 sigma. All variables generate out-of-specification products. Finally, the quality level turns out to be very low, affecting the company's reputation and generating possible significant financial losses, estimated at around $4137,13 for each shipment of products to customers abroad.
