PROBLEM TO BE SOLVED: To enhance the possibility of being able to extract a workflow having a high utility value.SOLUTION: A computer is made to execute processing which calculates an update frequency due to each activity in each workflow on the basis of presence/no presence of update by each activity for each execution result of each workflow about each of a plurality of parameters used by a first workflow and a plurality of second workflows each obtained by adding one or more activities to the first workflow, extracts a first parameter from a plurality of parameters on the basis of a difference between an update frequency in the first workflow and an update frequency in the plurality of second workflows about each of the plurality of parameters, and extracts second workflow from among the plurality of second workflows on the basis of a difference between the value of the first parameter at the end of the first workflow and the value of the first parameter at respective ends of the plurality of second workflows. |
