A process for determining a root cause problem for an out-of-tolerance component manufactured by a plurality of operations performed on the component. The process can include providing manufacturing data from at least a subset of plurality of operations performed on a plurality of components and discovering an out-of-tolerance measurement on at least a subset of the plurality of manufactured components downstream from the plurality of operations. An auto-regression analysis between the out-of-tolerance measurement and the plurality of upstream operations can also be performed using the manufacturing data. A correlation between at least one of the upstream operations and the out-of-tolerance measurement can be found and the correlation can result in the identification of at least one upstream operation that is the root cause of the out-of-tolerance measurement. |
