An internal audit may find issues in the quality system that the major audit may not have found. However, it would seem that this might not be effective. With an internal audit, the audit is completed by the quality employee working at the company itself. One factor to consider is the fact that the auditor might not be completely honest with their findings because they work at the same company and they do not want to make the company look bad. In addition, when a person who works at the company is reviewing their own work, they might overlook certain aspects because they have seen it before. With a major audit, it is an outside person reviewing the work, so they will look in more detail at the company.
