Oracle HCM Cloud uses human workflow automation to route approval tasks through a predefined sequence. It controls workflows for processes like hiring and promotions. Users can define simple or complex task routing policies. The system is integrated with HCM to determine approvers based on factors like supervision hierarchy, responsibilities, and job level. Workflows allow humans to interact with processes, such as approving purchases. They provide full task lifecycle management including rerouting, escalating, and setting deadlines. An example transfer workflow is configured to require approval from a user if the employee's current salary is over $9,000 and in the sales department. Workflows integrate with personnel records to update status.
