The success of a company is directly linked to its economic objectives. One of the elementary objectives is to maximize profit by reducing the company's own costs in order to increase competitiveness in the market. State of the art is the function-oriented and unambiguous technical specification through the application of Geometrical Product Specifications (GPS). Linking costs related to the GPS system is currently only possible to a limited extent. This contribution presents an approach to quantify costs based on statistical tolerance analysis. The application is intended to determine the impact of a GPS-compliant specification in direct comparison to a non-compliant technical drawing by analyzing scrap rates. In this way, an assessment of the changes associated with the consistent application of the GPS system should be achieved. The results of the study show that a comparison is only possible to a certain degree due to the different characteristics. Based on this finding, an extended evaluation methodology is described.
