The manufacturing sector in the UAE plays a pivotal role in the national economy, contributing approximately 12.1% to the country’s GDP in 2024. With over AED 330 billion in industrial output and more than 800,000 workers employed across thousands of facilities, the emphasis on regulatory compliance and operational efficiency has never been greater. Understanding how to do internal audit of a manufacturing company is not just about regulatory adherence; it is a strategic function that enhances product quality, mitigates risks, and drives continual improvement.

Internal audits are essential for maintaining quality, ensuring adherence to ISO standards, and sustaining the long-term viability of operations. In the UAE, these audits are influenced by both global standards and local regulatory authorities such as the Ministry of Industry and Advanced Technology (MoIAT) and Emirates Authority for Standardization and Metrology (ESMA). As the UAE’s manufacturing landscape evolves in 2024 and 2025, knowing how to do internal audit of a manufacturing company effectively is critical to aligning with industry-specific requirements, digital transformation initiatives, and sustainability goals.

Understanding the Regulatory and Operational Context in the UAE

To conduct a successful internal audit, manufacturers must begin by acknowledging the regulatory environment. UAE manufacturers are mandated to align with ISO 9001 for quality management, ISO 14001 for environmental practices, and ISO 45001 for occupational health and safety, with certification costs ranging from AED 3,000 to AED 25,000 depending on scope. Furthermore, compliance with ESMA directives and MoIAT policies—which include participation in 71 international technical committees—is crucial, especially when handling sensitive sectors such as food, chemicals, electronics, or pharmaceuticals.

The push toward digital manufacturing, smart factories, and Industry 4.0 has accelerated post-pandemic, with national targets to boost manufacturing output by 30% and add $6.8 billion to GDP by 2031. This necessitates a shift in audit approaches. Internal audits must now encompass digital compliance (e.g., cybersecurity controls, now included in >70% of UAE audits), data integrity checks for MES systems, and calibration record validation—areas where 35% of manufacturers report gaps. Alongside traditional quality metrics, auditors must evaluate Industry 4.0 readiness, supplier traceability (critical for 45% of high-risk sectors), and alignment with MoIAT’s Smart Manufacturing Program, which has actively onboarded enterprises since February 2022.

9. Prioritize Audit Findings
   Classify issues into:

   • Critical risks

   • Major gaps

   • Minor issues
     Focus efforts based on risk-based auditing principles.

Step 3: Reporting Phase

10. Compile Audit Report
    Include:

    • Executive summary

    • Evidence-backed findings

    • Root cause analysis (e.g., 5-Why, Fishbone Diagram)

    • Corrective action recommendations

11. Include Relevant Benchmarks
    Reference UAE-specific metrics like:

    • Inventory turnover ratio (6.5x/year)

    • Downtime averages (5%)

Step 4: Follow-Up Phase

12. Track Corrective Actions (CAPA)
    Monitor and verify completion of all corrective and preventive action items.

13. Integrate Results into Management Review
    Use audit findings to:

    • Inform strategic decisions

    • Adjust future audit plans and risk assessments

14. Conduct Ongoing Training
    Ensure auditors are continuously updated on:

    • ISO 9001 audit techniques

    • UAE-specific compliance standards

Quantitative Insights and National Benchmarks

Manufacturing audits in the UAE benefit from a growing set of quantitative benchmarks. First-pass yield rates in high-performing UAE factories reach 98%, while the average hovers around 94%. Inventory turnover is improving, especially in sectors like food processing and pharmaceuticals, with some achieving 8.5 times annually.
