The most important thing for mitigating ethical risk when establishing accountability for control ownership is to ensure that the performance metrics balance business goals with risk appetite. Performance metrics are the measures that evaluate the achievement of the objectives or the performance of the processes or controls.
Business goals are the desired or expected outcomes or results of the business activities or processes. Risk appetite is the amount and type of risk that the organization is willing and able to take. Ethical risk is the risk that arises from the violation or breach of the ethical principles or standards of the organization or the profession. To mitigate ethical risk, the performance metrics should balance business goals with risk appetite, meaning that they should not encourage or reward excessive or inappropriate risk-taking or unethical behavior, but rather promote and support responsible and ethical risk management and decision making. The other options are not as important as ensuring performance metrics balance business goals with risk appetite, as they are related to the documentation, communication, or monitoring of the processes or controls, not the evaluation or alignment of the performance metrics.
