What Happens During an ISO Audit? Step-by-Step
ISO audits follow a well-defined structure to ensure every aspect of the management system is thoroughly assessed. This approach guarantees consistency and fairness in audit execution.
A typical ISO audit follows a structured process to ensure thoroughness and objectivity:
- Audit Planning – Scope, objectives, and schedules are defined. Lead auditors often trained via lead auditor courses take charge.

- On-Site Assessment – Real-time evaluations and staff interviews are conducted.
- Audit Report Generation – Findings are documented, including nonconformities.
- Corrective Action and Follow-Up – Gaps are addressed, and results verified in follow-up reviews.
Understanding Nonconformities & Audit Outcomes
Audit outcomes highlight whether a system is functioning as expected. Nonconformities indicate gaps that need to be addressed for the system to be fully compliant.
Auditors classify findings into categories that determine the urgency and nature of corrective actions:
- Major Nonconformity: Indicates serious non-compliance that must be addressed before certification.
- Minor Nonconformity: Small deviations that require correction but don’t halt certification.
- Observation: Suggestions or potential risks that may become issues if not addressed.
Professionals trained through iso 27001 lead auditor training course are better equipped to manage and respond to these findings effectively.
