A system for identifying a manufacturing tool causing a failure, includes a data generating module generating factorial effect data, based on information on a failure lot group by using an orthogonal array, a chart generating module generating a factorial effect chart based on the factorial effect data, a selection module selecting failure lots caused by the same reason for a failure from among the failure lot group, based on the factorial effect chart, and an identification module identifying a manufacturing tool used as a common tool for the selected plurality of failure lots, based on history information of the manufacturing tool group.
