Abstract

A work-flow support having: a processing wait task storage unit that temporarily stores a task execution request and a rule interpretation execution unit executes a task corresponding to the execution request stored in the rule interpretation execution unit under the execution of another task according to rules. The rule interpretation execution unit and the task history storage unit manage history information about each task which has initiated its execution. The rule interpretation execution unit allows a task connection information storage unit to store therein connection information for connecting history information about the task corresponding to the execution request and another task to be executed to one another. When the history information about a task corresponding to a new execution request stored in the processing wait task storage unit is already stored in the task history storage unit, the rule interpretation execution unit notifies the corresponding history information to a request source of the new execution request and reflects the history information about the task corresponding to the new execution request and the history information about the already-stored task on connection information as history information about the same task.
