    In the present research work is detailed in a comprehensive manner the application of Statistical Quality Control (SQC) in the process of making T-shirts and their impact on customer satisfaction (quality). Throughout the study, the statistical comparison of the effect of the SQC on the main variables of purchase impact on the client is made, such as the final lengths of the garment of the main components of the garments: sleeves, length and width, between: 1. The state or initial situation of the quality of shirts (process without the implementation of statistical quality control) and 2. The improved condition of the quality of shirts (process, after the implementation of statistical quality control). For this purpose, the calculation of the process capacity indexes is taken as a function of the permitted variability and the objective value defined in the design specifications (voice of the client), among them: the Potential Capacity of the process (Cp), the Potential inverse potential (Cr), Potential capacity with respect to process centering (Cpk), Process centering (K), Taguchi index (Cpm) and comparing them in the two instances mentioned above (process without statistical control of the quality and process implemented the statistical control of the quality). The elaboration and comparison of the graphic quality tools is included in this stage: statistical control chart and the process capacity normality histogram. The results are evident, since a considerable improvement of the quality of the process was obtained, as the percentage and the number of defective units were reduced, basically based on the reduction of the variability and the centering of each process, and the influence is statistically demonstrated of statistical quality control to improve customer satisfaction. As a final part, a Statistical Quality Manual for continuous variables is designed, applied to the company's T-shirt production process, based on the DMAIC continuous improvement methodology, which incorporates tools such as: statistical control chart Xbarra, chart R, the histogram of process capacity, automatic sheets for calculating capacity indexes, among others, with the aim of maintaining the improvement achieved and ensuring compliance with the quality of quantitative variables.
