Abstract:
1. A quality improvement system using an FMEA table, the system comprising: a defect data collecting unit configured to collect defect data about a defect in a manufacturing or inspection process; an FMEA table update unit configured to update the FMEA table online based on the data collected by the defect data collecting unit; and a work instructing apparatus that displays a work instruction to an operator, wherein the FMEA table includes a failure mode, the number of occurrences of the failure mode, and an effect caused by the failure mode; wherein the FMEA table update unit includes an FMEA table editing unit to edit the FMEA table, the FMEA table editing unit configured to edit the number of occurrences of the failure mode when a row including a set of an occurred failure mode and an effect corresponding to the occurred failure mode is previously defined in the FMEA table, and to insert the row into the FMEA table when the row is not defined in the FMEA table; wherein the FMEA table update unit includes a failure mode estimate unit configured to estimate the failure mode based on the effect that corresponds to the defect data collected by the defect data collecting unit, wherein the failure mode estimate unit has association data that indicates association between the defect data and the failure mode; wherein the failure mode estimate unit is configured to estimate the failure mode respective to the defect data collected based on the association data wherein the FMEA table includes the work instruction that corresponds to the failure mode, wherein the FMEA table update unit notifies the work instructing apparatus of the work instruction, wherein the work instruction includes a first work instruction and a second work instruction; wherein the first work instruction includes an emergency action for the manufacturing or inspection process and a specific work instruction about treatment of a product being manufactured; wherein the second work instruction includes a work instruction in relation to a work standard of the manufacturing process; wherein the failure mode estimate unit controls the work instructing apparatus to display the defect data based on the FMEA table when the defect data collecting unit detects the defect data and the failure mode estimate unit identifies a corresponding work instruction or the failure mode; and wherein the work instructing apparatus includes a control unit for inputting by an operator a result showing whether a work corresponding to a displayed work instruction has been done or not and for recording the result into the FMEA table, the system further comprising:
