The objective of this report was to implement the Statistical Quality Control techniques to improve the defective products index of the company Inversiones Industriales del Amazonas SAC, a company dedicated to the footwear industry, located in the district of El Porvenir in Trujillo . Within the Statistical Quality Control, there are different techniques and tools to apply to obtain improvements in quality and productivity in any field of industry; It is for this reason that, in order to solve the main problem found in terms of Quality within the company under study, which is the high index of defective products, two techniques are developed mainly, the first is, Letters of Control for Attributes and The second is the Acceptance Sampling Plan. The techniques mentioned above require the use of tools, for example, in the case of control charts, check sheets and control charts are used, and in this technique, an improvement was made in terms of labor where Applies Performance Evaluation; On the other hand, when applying Acceptance Sampling Plan, one of the causes that causes a high index of defective products is improved, which becomes the low quality of raw material, for which use is made of certain tools, such as Brainstorming , Scatter Charts, Ishikawa Diagram, and Supplier Evaluation Formats. All this is reflected in the improvement obtained when comparing initial indicators and those measured after the proposed improvements, which is shown below: • By implementing Statistical Quality Control Letters, the defective products were reduced by 25%, resulting in a monetary improvement of S /. 188.28 per month. • Through the application of the Statistical Quality Control Letters, a 100% improvement in the instability of the process was obtained, since an instability of 6% was found and reduced to 0% • When implementing Acceptance Sampling Plan, it was possible to reduce the index of defective products by 71.4%, resulting in a monetary improvement of S /. 416.51. • The project is viable, since through the Financial Economic Evaluation developed, a VNA of S /. 177 050.67 and a TIR of 152.74%.
