To evaluate operating effectiveness

To evaluate the operating effectiveness of controls, conducting control testing is essential. Control testing involves examining whether controls are operating as intended and are effective in mitigating risks. This type of testing assesses the design and implementation of controls to ensure they are functioning properly and achieving their intended purpose. Substantive testing, on the other hand, focuses on verifying the accuracy and validity of transactions and data, rather than the effectiveness of controls.References:
