In general, the determination of more parameters for error prevention along the process chain is associated with higher costs. A compromise must therefore be found between the costs of prevention and the costs of errors that actually occur. Quality gates are a concept that sets inspection and decision points along the process chain to evaluate the quality of an (intermediate) product . Quality itself can be defined as a "… degree to which a set of inherent characteristics or features of an object fulfills requirements" . This set of characteristics can e.g. relate to a process or an (intermediate) product. A distinction must therefore be made between those two. It is however important to acknowledge the influence of the process parameters on the product features which is why both the process and product quality need to be considered. Especially for large-scale production inline inspections with automated evaluation are most suitable for potential decision making with regard to the control of downstream processes . The right determination of the most important parameters and features however can be based on experience and historical data using feature selection methods like recursive feature elimination .
