There are many studies about the process capability indices which are used to study if a process can meet specification. Unfortunately, there are few studies about the product capability. So, the main aim of this thesis is to present an alternative to determine the product capability. It is important to determine if when the quality characteristics of a product are assembled the final product will still meet the specification. This study proposes an approach to determine the product capability using the C_pm to analyze the capability of the quality characteristic. Also, this thesis proposes the use of weight to determine the influence of the quality characteristic in the final quality of the product. This study was divided in four steps, the first one the definition of the product and quality characteristics that will be used. The second one is the simulation study where the estimators used to determine the process capability indices are defined. The third one is the characteristic study which presents the CPI and the yield for the characteristics analyze. The last step is the product capability study which presents the product capability for the product.
