PROBLEM TO BE SOLVED: To provide a traceability management device capable of reducing an amount of work for setting traceability data if a document is revised.SOLUTION: A upstream document 71 before revision and an upstream document 72 after revision stored in an electronic document storage device 7 are compared by comparison means 81 on a region-by-region basis of traceability data 91 so that a character change rate will be obtained, while a downstream document 73 before revision and a downstream document 74 after revision are compared by the comparison means 81 on a region-by-region basis of the traceability data 91 so that a character change rate will be obtained. Further, the character change rates are determined by setting means 82 and then new traceability data is set on a region which needs to be changed as the result of determination.SELECTED DRAWING: Figure 1 |
