Internal audit
Examine the organization’s system against defined criteria and its own planned arrangements.
Primary outcome · Internal assurance and improvementManagement-system auditing
QSE auditing should use a defined scope, criteria, sampling approach, and reporting method to produce supported findings the organization can act on.

Choose by decision need
The objective determines the criteria, evidence, sampling, independence, competence, report, and appropriate next action.
Examine the organization’s system against defined criteria and its own planned arrangements.
Primary outcome · Internal assurance and improvementEvaluate a supplier against agreed requirements, scope, evidence, and customer priorities.
Primary outcome · Supply-chain decision supportCompare the current condition with named requirements to identify implementation work.
Primary outcome · A structured view of gapsAssess whether the system and evidence appear ready for the next external milestone.
Primary outcome · A readiness position—not certificationA traceable method
The method makes clear what was examined, how conclusions were reached, and where responsibility moves after reporting.
Confirm objective, scope, criteria, sites, processes, timing, access, independence, and reporting expectations.
Interview people, observe work, review records, and sample evidence in relation to the defined criteria.
Compare evidence with criteria, test significance, and distinguish findings from advice or assumptions.
Communicate findings, clarify required response, and transfer corrective-action ownership to the client.
Independence and boundaries
Objectivity depends on competence, impartiality, disclosed relationships, and separation from responsibility for the work being audited.
Audit outputs
Confirmed objective, scope, criteria, dates, participants, and sampled areas.
Findings linked to applicable criteria and supported by sufficient evidence.
Clear distinction among conformity, nonconformity, observations, and improvement discussion as agreed.
Summary conclusions, unresolved limitations, and corrective-action handoff expectations.
Protected records and distribution consistent with confidentiality agreements.
Prepare the audit
Share the audit objective, named criteria, scope, sites or suppliers, relevant processes, target timing, previous findings, language or access constraints, and any QSE involvement that could affect independence.
Audit duration, team competence, sampling, travel, report format, finding classifications, follow-up, and commercial terms require confirmation.
