1. A computer system for determining a condition of category division of a key performance indicator (hereinafter, referred to as a KPI) from multiple pieces of workflow execution information, each of the multiple pieces of workflow execution information having at least one set of a type of the KPI and a value associated with the type, the computer system comprising: a memory; and a processor in communication with the memory, wherein the processor is configured to: divide the multiple pieces of workflow execution information into a division number for the type of the KPI wherein the multiple pieces of workflow execution information belong to multiple groups associated with the type of KPI; generate a graph for each of the multiple groups after the division into the division number, from workflow execution information belonging to the multiple groups; calculate graph edit distances for any two graphs; generate a new group by merging two graphs having the shortest graph edit distance; calculate a graph edit distance between the new group and another graph; repeat the generation of the new group and the calculation of the graph edit distance between the new group and another graph until the graph edit distance is more than a certain fixed edit distance; determine, in response to the graph edit distance for the new group being more than the certain fixed edit distance, a threshold value, wherein the threshold value defines the new group as the condition of the category division; displaying the new group and the threshold value to a user; accessing, by the user, a help page on a webpage; identifying, by the processor, that the help page is associated with workflow execution information relating to the new group associated with the type of KPI; automatically detecting a threshold value for the type of KPI in response to identifying the help page being associated with workflow execution information relating to the new group associated with the type of KPI; and displaying the help page to the user in response to determining that the type of KPI is above the threshold value.
