A database stores as administration information of a program, source code identification information for identifying a source code representing the program, function unit identification information for identifying function units of the program which are defined by the source code, and an address of an administrator of the source code. An evaluation computer performs an evaluation process on a program to be evaluated to determine whether the program includes any error command or module, and when determining that the program includes an error command or module, obtains administration information of the program to be evaluated from the database and externally sends source code identification information and function unit identification information included in the obtained administration information to an address included in the obtained administration information.
