Abstract: A method for predicting an End of Line (EOL) quality of a product in an assembly plant is provided. The method includes performing a downstream test on a plurality of sub-components for determining a set of attributes. The method also includes receiving, by a control module, the set of attributes of the sub-components. The method further includes performing, by the control module, a root cause investigation on the set of attributes of the sub-components for identifying a subset of attributes from the set of attributes. The subset of attributes contributes to lowering the EOL quality of the assembled product. The method includes developing and validating, by the control module, dynamic prediction models based on the identified subset of attributes associated with the sub-components. The method also includes predicting, by the control module, the EOL quality of the assembled product based on the dynamically validated prediction model.
