A technique is provided that enables efficient determination of the executability of a workflow while considering changes in processing target data that are sequentially processed in the workflow. A workflow management apparatus includes: a processing result acquisition unit which acquires information about processed data that is processed in a processing unit of plural processing units; an execution condition acquisition unit which acquires information about an execution condition of processing in a processing unit located downstream from the processing unit for which the information about the processed data is acquired by the processing result acquisition unit; and an executability determination unit which determines whether or not the processed data with its information acquired by the processing result acquisition unit can be processed in a processing unit located downstream from the processing unit in which the processed data is processed, on the basis of the information about the execution condition acquired by the execution condition acquisition unit.
