1. An information processing system including at least one information processing apparatus and also including at least one program respectively executing predetermined processes, the information processing system comprising a hardware processor and a hardware storage, wherein the hardware storage is configured to implement a first memory unit storing, for each application executing a sequence of processes using electronic data, flow information which defines program identification information for identifying the at least one program executing each process of the sequence of processes and an execution order of the at least one program, application (app) identification information identifying application (app) identification information, and flow identification information identifying flow identification information while associating the flow information, the application (app) identification information, and flow identification information; and a second memory unit storing first flow identification information identifying first flow information which defines the program identification information for identifying the at least one program executing each process of a first sequence of processes and an execution order of the at least one program, program identification information identifying the at least one program executing each process of a second sequence of processes, which is automatically executed in response to an error that occurs in the first sequence of processes, and second flow identification information identifying second flow information defining the execution order of the at least one program while associating the first flow information, the program identification information, and the second flow identification information, wherein the hardware processor is configured to implement a receiving unit receiving a request including the application (app) identification information, the first flow identification information, information related to electronic data used in the first sequence of processes from one apparatus among from at least one apparatus coupled to the information processing system; and a process executing unit automatically causing each program of the at least one program identified by the program identification information defined by the first flow identification information included in the request from among the flow information stored in the first memory unit in association with the application (app) identification information included in the request received by the receiving unit to be executed according to the execution order defined in the first flow information to execute the first sequence of processes the electronic data, wherein the process executing unit, in response to the error occurring in the first sequence of processes, automatically causes each program of the at least one program identified by the program identification information defined by the second flow information stored in the first memory unit to be executed in the execution order defined in the second flow information to execute the second sequence of processes using the electronic data.
