Defining Audit Types Based on Auditor-Auditee Relationships

At the core of auditing lies the relationship between the auditor and the auditee, which determines the classification of the audit type. This relationship impacts the audit’s objective, scope, and level of independence, which directly influences audit effectiveness and credibility in both exam and professional settings.

First-Party Audits (Internal Audits) are conducted by an organization on itself, typically by its own employees or internal audit teams. The goal is primarily self-assessment to ensure compliance with internal procedures and external standards. Since the auditor and auditee belong to the same organization, this audit is considered internal and focuses on continual improvement and regulatory adherence.

Second-Party Audits (Supplier Audits) are performed by an organization on its suppliers or contractors. Here, the auditor represents the client company, assessing the supplier’s compliance with contractual or regulatory requirements. This type of audit is external to the supplier but internal from the client’s perspective. It emphasizes vendor management and supply chain quality assurance, vital for purchasing decisions and risk mitigation.

Third-Party Audits (Certification or Registration Audits) are conducted by independent external bodies with no commercial interest in the auditee. These audits are impartial evaluations, often required to achieve or maintain certifications such as ISO 9001. The auditor is completely detached from the auditee, guaranteeing objectivity and broad acceptance of the audit findings in the marketplace and regulatory domains.

Analyzing Audit Types in Context: Internal vs. External

Understanding the distinction between internal and external audits helps clarify how first-, second-, and third-party audits operate in practice:

Internal context: First-party audits are a hallmark of internal auditing. The organization uses this type to monitor and improve its own processes, verify compliance, and prepare for external assessments. Internal audits typically focus on risk areas, process effectiveness, and management system conformance, providing feedback for continuous improvement.

External context: Both second-party and third-party audits happen externally relative to the auditee. However, they differ in the relationship and purpose. A second-party audit is customer-driven and often commercial, ensuring suppliers meet the client’s quality and contractual requirements. A third-party audit brings full independence by a neutral organization, often for certification, accreditation, or regulatory endorsement, providing credibility beyond the client-supplier relationship.

For auditors and candidates eyeing the CQA exam, distinguishing these audits is key since questions regularly probe your ability to interpret audit type applications, select appropriate audits, and recognize benefits and challenges associated with each type.

Real-life example from quality auditing practice

Imagine you are an internal auditor at a manufacturing company preparing for an ISO 9001 surveillance audit. Your role is to conduct first-party (internal) audits of production and quality control processes to identify any nonconformities before the external certification body arrives. During the audit, you notice a supplier’s raw material batch causing defects. You then recommend a second-party audit to be conducted by your company’s procurement team to evaluate the supplier’s quality system and compliance with your purchasing requirements. Subsequently, the external certification body performs a third-party audit to confirm your organization’s overall compliance with ISO 9001 standards.

This scenario highlights how the three audit types interplay in a practical quality management system, emphasizing their distinct roles yet complementary contributions to sustaining quality and compliance.
