Process audits are commonly carried out on a quarterly basis to ensure consistent compliance, process stability, and improvement. However, frequencies vary based on risk and industry, ranging from daily/weekly for high-risk processes to annually for low-risk, established, or, as mentioned in TCO Certified, 12-to-36-month cycles.
