An execution log generation apparatus generates an execution log upon receiving, for each job operation, job operation data indicating content of a job operation performed in a job procedure from a job processing apparatus that performs job processes through job procedures. The execution log generation apparatus includes a definition file holding unit that holds a definition file in which job operations performed in the job procedures are defined along a flow of the job processes and the job procedures, and in which output items to be output as execution logs for the each job operation are listed in a common format; and an execution log output unit that selects, from the definition file, an output item corresponding to a job operation contained in the job operation data, and outputs, as an execution log, the same output item as the selected output item from the job operation data.
