1. An information processing method implemented by an information processing system including a first information processing apparatus including a first processor and a second information processing apparatus including a second processor, and a terminal apparatus including a third processor, comprising: displaying a setting screen for defining a workflow implementing a plurality of processes in a set order in a logic flow area of the setting screen; setting a plurality of defined processes and the order of executing the defined processes via the setting screen; setting, with respect to each of the defined processes, a host device of a selected process from among the first information processing apparatus and the second information processing apparatus in a physical flow area of the setting screen; creating a work flow information further defining the defined processes, order of executing the defined processes, and the host device by connecting task icons with an arrow indicating an order of performance and connecting the task icons disposed in the logic flow area with host device icons disposed in the physical flow area with a line so as to associate the task icons and the host device icons with each other; and acquiring data of a target process to be executed according to the work flow information so as to start the process of the work flow information, determining, based on a host device of each defined process further defined with the work flow information stored in a storage, a respective defined process to be executed by one of the first processor and the second processor from among defined processes further defined with the work flow information, and executing the respective defined process determined to be executed by one of the first processor and the second processor, respectively.
