    Control estadístico de procesos y su relación con la calidad del calzado formal para varones, producido en la ciudad de Ambato

    Companies in the footwear sector experience a loss of competitiveness caused by poor control in the production process, hence the statistical control of processes is a tool that has not been widely used in the productive sector, which has not allowed the management of costs and quality standards that the national market requires in the production of men's footwear. This is the analysis of the impact of statistical control on the compliance of quality parameters in footwear, which is achieved through descriptive research applied through a survey applied to 200 companies engaged in this productive activity in the city of Ambato; whose results show that companies do not use controls in the production process, in addition to not using statistical tools to track production historically, it is determined as necessary to apply controls in the production process that involves statistical control the production operators so that the compliance of final product standards can be improved that can be applied to solve the problems that afflict the sector, so that the product is standardized and the product with failures is reduced. From this it is concluded that it is necessary to implement quality manuals, which are proposed through a pilot for the footwear company Barona, which as a family company requires guidelines to raise awareness among managers and guide work to the employees. With the implementation of the manual, the basic tool for the development of quality management activities is provided, which will be the foundation to include the production control tools that ultimately allow the formation of a culture of quality in the organization and visible results that strengthen the application of the statistics of quality in the productive process of shoemaking.

    La calidad del proceso productivo y la aplicación del control estadístico en el sector de la confección textil

    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.
