A risk practitioner is a person who is responsible for performing risk management activities, such as identifying, analyzing, evaluating, treating, monitoring, and communicating risks. When an organization is implementing a project to automate the purchasing process, including the modification of approval controls, the task that is the responsibility of the risk practitioner is to verify that the existing controls continue to properly mitigate the defined risk. This means thatthe risk practitioner should ensure that the automation and modification of the approval controls do not introduce new risks or change the existing risk profile, and that the controls are still effective and adequate for the purchasing process. The risk practitioner should also monitor the performance and compliance of the controls, and recommend any improvements or adjustments as needed.
