To solve the problem of conventional workflow systems that these do not allow for users' skills, implementing the same process whether the users' skills are sufficient or not, with the result that processes cannot be omitted even if the users' skills are sufficient, leading to wasteful operation.

An issue management function 142 acquires skills by requesting a skill decision function 143. The skill decision function 143 decides a user's skill by referencing a history table 145 and a skill decision table 146.
