Internal audit

Plain-language summary

Audit your own system at planned intervals: does it meet your requirements and the standard's, and is it effectively implemented — with objective auditors, defined criteria, results to management, corrections without delay, and records.

What the clause is really asking

Conduct internal audits at planned intervals; plan the programme considering importance, changes and previous results; define criteria/scope per audit; select auditors ensuring objectivity and impartiality (no one audits their own work); report to relevant management; correct and take corrective action without undue delay; retain programme and result records.

What auditors look for

Auditors audit your audit programme: risk-based planning (problem areas audited more?), full coverage over the cycle, auditor independence, finding quality (real findings or polite ticks?), and the speed/closure of resulting actions. A programme that never finds anything draws suspicion, not praise.

Typical evidence

Audit programme/schedule with rationale; audit plans and reports; auditor independence evidence; finding and corrective action records with closure.

How to comply — recommendations

Schedule by risk, not by calendar convenience: double frequency on processes with complaints or changes. Cross-audit between departments for independence. Track finding closure age as a KPI — an audit system is judged by what happens after the report.

Common nonconformities

Same areas audited annually regardless of performance; auditors auditing their own department; findings open for months; audits producing nothing but 'opportunities'.
