A method for adjusting a condition for determining a quality of an inspection object in a quality determination device comprising a database, a processing unit, a user input unit, and an output unit, the method comprising: acquiring, by the processing unit, measurement values for structures of a plurality of inspection objects from the database; determining, by a quality determination unit in the processing unit, whether each of the plurality of inspection objects is good or defective by comparing error values of the measurement values with respect to design values of the structures with a reference value which is used for determining whether each of the plurality of inspection objects is good or defective; identifying, by the quality determination unit in the processing unit, one or more inspection objects in which a determination error has occurred, among the plurality of inspection objects; and determining, by a determination result generation unit in the processing unit, at least one candidate reference value to reduce the number of the one or more inspection objects in which the determination error has occurred, characterized by further comprising: generating, by the determination result generation unit in the processing unit, a graph comprising the reference value, the at least one candidate reference value, indicated by a candidate reference value indicator, and a result of determining whether each of the plurality of inspection objects is good or defective, and displaying the graph through the output unit, wherein the determining the at least one candidate reference value comprises determining, based on a range of good error values stored in the database, at least one of the values greater than or equal to a maximum value of the range of the good error values to be the at least one candidate reference value, and wherein the range of the good error values is estimated by a determination review device based on a distribution of the error values. acquiring, by the processing unit, measurement values for structures of a plurality of inspection objects from the database; determining, by a quality determination unit in the processing unit, whether each of the plurality of inspection objects is good or defective by comparing error values of the measurement values with respect to design values of the structures with a reference value which is used for determining whether each of the plurality of inspection objects is good or defective; identifying, by the quality determination unit in the processing unit, one or more inspection objects in which a determination error has occurred, among the plurality of inspection objects; and determining, by a determination result generation unit in the processing unit, at least one candidate reference value to reduce the number of the one or more inspection objects in which the determination error has occurred, characterized by further comprising: generating, by the determination result generation unit in the processing unit, a graph comprising the reference value, the at least one candidate reference value, indicated by a candidate reference value indicator, and a result of determining whether each of the plurality of inspection objects is good or defective, and displaying the graph through the output unit, wherein the determining the at least one candidate reference value comprises determining, based on a range of good error values stored in the database, at least one of the values greater than or equal to a maximum value of the range of the good error values to be the at least one candidate reference value, and wherein the range of the good error values is estimated by a determination review device based on a distribution of the error values. generating, by the determination result generation unit in the processing unit, a graph comprising the reference value, the at least one candidate reference value, indicated by a candidate reference value indicator, and a result of determining whether each of the plurality of inspection objects is good or defective, and displaying the graph through the output unit, wherein the determining the at least one candidate reference value comprises determining, based on a range of good error values stored in the database, at least one of the values greater than or equal to a maximum value of the range of the good error values to be the at least one candidate reference value, and wherein the range of the good error values is estimated by a determination review device based on a distribution of the error values.
