It's a system. The deputy minister obviously can't look at every contract or every detail. However, they must see to it that someone is responsible for ensuring that controls are in place, that governance systems are in place, and that those controls are checked on a regular basis to make sure that they are working. A control never works 100%. Good controls will eventually uncover weaknesses. That is what good controls are about. They are there to ensure that departmental programs or initiatives are delivered in accordance with rules, policies and legislation.
