A computer system executable method is provided for managing resources in an automated workflow system for manipulating a work item, the work item being stored in a database of work items for subsequent execution by an operator and meeting a predetermined criteria. A first definitional data item is stored in a memory, the first definitional data item affecting how the workflow system processes work items meeting the predetermined criteria. A directive is received from an administrator to remove the first definitional data item from the memory. A mark is set, the mark being associated with the first definitional data item to indicate that the first definitional data item is to be removed from the memory. If a second definitional data item is normally able to be made dependent on the first definitional data item, the mark is used to prevent the second definitional data item from being made dependent on the first definitional data item after the mark was set. The mark is used to prevent the first definitional data item from affecting another work item if the other work item failed to meet the predetermined criteria until after the mark was set. The work item is processed until the work item no longer meets the predetermined criteria. It is determined whether any other definitional data items are dependent on the first definitional data item. Depending on the outcome of the determination, the first definitional data item is removed from the memory.
