Abstract: A case management method that reduces the number of manual operations, prevents manual errors, guarantees updated data, and enables knowledge of the present location of a storage file. In the case management method, case information involving a processing deadline is input to the management computer. At least one event, which is a task including a single operation and involving the processing deadline or a task including a series of operations and involving the processing deadline, is generated. Workflows, which are series of operations performed in a section that is determined beforehand in accordance with the type of generated event, are stored in a database. A predetermined workflow is selected from the stored workflow. An event pool storing the generated event in association with the selected predetermined workflow is generated in the database.
