Administering control questionnaires to individuals with primary responsibilities in the process can yield valuable information about processes and controls. However, one significant drawback is that the information gathered may be limited regarding the actual functionality of the controls. This approach relies on the respondents' knowledge and perceptions, which may not accurately reflect the effectiveness of the controls in practice. Moreover, respondents might not fully understand the auditor's intentions or may provide biased or incomplete information, thereby limiting the depth of insights into how controls function in real-world scenarios.References:
