Control self-assessment (CSA) is a process where managers and work teams within an organization evaluate the effectiveness of their own internal controls and take responsibility for the design and functioning of those controls. It is a collaborative and participatory approach that typically involves workshops facilitated by internal auditors but does not involve traditional audit tests by auditors. Instead, the role of auditors in CSA is more about facilitation, guidance, and recording. Therefore, traditional audit tests to identify control weaknesses are not characteristic of CSA, making option C the correct answer.
