What Is Difference Between External Audit and Internal Audit: Explained With FAQs

What is external audit in the pharmaceutical industry?

An external audit is typically scheduled or unannounced, designed to assess and verify compliance with both national and international pharmaceutical regulations and standards. The successful completion of such an audit may lead to critical outcomes, including certifications, regulatory approvals, and the granting of operational licenses, ensuring adherence to industry best practices and legal requirements.

What is an Internal Audit in the pharmaceutical industry?

An internal audit in the pharmaceutical industry is a thorough and independent evaluation of a company’s operations, processes, and systems to ensure compliance with internal procedures, regulatory standards, and quality requirements. Conducted by the company’s internal audit team, these audits are a key component of a robust quality management system. They play a vital role in identifying potential risks, non-conformities, and areas for improvement, ultimately driving enhancements in product quality, safety, and operational efficiency. By proactively addressing these findings, internal audits help safeguard regulatory compliance and support continuous improvement across the organisation.

What Is Difference Between External Audit and Internal Audit?

The following are the 5 main differences between External Audit and Internal Audit:

1. Purpose and Scope:

• External Audit: Conducted to assess compliance with national and international regulatory requirements, ensuring the company meets industry standards and legal obligations. It often focuses on broader issues like certification, licensing, and approval processes.
• Internal Audit: Aimed at evaluating internal processes, systems, and procedures to ensure compliance with company policies and internal standards. It is more focused on continuous improvement and risk management.

2. Independence:

• External Audit: Performed by third-party, independent auditors who are external to the company. Their objective is to provide an unbiased assessment of the organisation’s compliance.
• Internal Audit: Conducted by employees or internal teams within the company. Although independent from daily operations, they are still part of the organisation and work toward internal improvement.

3. Frequency:

• External Audit: Typically scheduled at regular intervals, often annually or as required by regulatory bodies, and can be either planned or unannounced.
• Internal Audit: Conducted more frequently, often as part of a continuous or periodic quality management system. Internal audits are planned based on the company’s internal policies and risk assessments.

4. Outcome and Impact:

• External Audit: The outcome can lead to external certifications, regulatory approvals, or operational licenses, which are crucial for market access and legal compliance.
• Internal Audit: The outcome focuses on identifying inefficiencies, non-conformities, and opportunities for improvement. It may not result in formal certifications but it supports internal quality control and process optimisation.

5. Focus Area:

• External Audit: Primarily focused on ensuring compliance with regulatory standards, industry guidelines, and laws such as Good Manufacturing Practices (GMP), Good Clinical Practices (GCP), or Good Distribution Practices (GDP).
• Internal Audit: Concentrates on the effectiveness of internal controls, risk management, and the overall performance of business operations, including adherence to internal policies and procedures

Conclusion

Both internal and external audits are integral to maintaining high standards in the pharmaceutical industry. Internal audits help companies identify areas for improvement, ensuring compliance with internal procedures and regulatory requirements while driving continuous enhancement in product quality and operational efficiency. External audits, on the other hand, provide an objective review, verifying adherence to national and international standards, and often result in essential certifications, regulatory approvals, or operational licenses. Together, these audits foster a culture of accountability, compliance, and quality, ultimately ensuring the safety and efficacy of pharmaceutical products in the market.
