External audits are generally used for assessing various aspects of a company's performance, such as production efficiency, sales effectiveness, and customer satisfaction.
Step-by-step explanation:
External audits refer to the independent examination of an organization's financial statements, operations, or other aspects by an external auditor or auditing firm.
