Abstract: A computer system, which is configured to support a work formed of a combination of tasks, manages work management information for storing logs each including identification information on a work, an object of the work, a combination of tasks for the work, and evaluation information indicating an evaluation obtained by a user for a result of the work. The computer system obtains, in a case where a new work is to be executed, logs including the same object as an object of the new work; calculates an evaluation value of the work corresponding to the logs based on the evaluation information included in the logs; selects a combination of tasks recommended for the new work from among combinations of tasks included in the logs, based on the first evaluation value; and presents the selected combination of tasks to a user of the new work.
