Abstract

In order to fulfill the needs of its customers, the companies have been searching different ways to improve their production line. The alternative was to make an analysis using the capability indexes, avoiding the production of defective products and also unnecessary losses. The objective of this project is to check the diffusion of the application of techniques to evaluate the capability of process in the industries, and to this goal to be achieved, publications about the subject matter were found. After that, the study of the diffusion was made by key information. To greater credibility and reliability of this research, it was used the method of systematic literature review. It is a scientific procedure to investigate, to search and to analyze previous publications about a subject. Despite of the difficulty of finding relevant articles, the data showed that the study using the capability indexes – Cp and Cpk – increased over the years. It also proved that all data have normal distribution, and most results are about processes unable to produce within tolerance.
