Quick Answer

A quality audit is a structured review that checks whether work, a process, or a product meets a defined standard. It can be internal, run by a company's own team, or external, run by a certification body or client. Findings are logged as conformances or non-conformances, and any gap drives a corrective action through to verified closure.

What is a quality audit?

A quality audit is a planned, evidence-based review that compares what is actually happening against a defined standard, whether that is a written procedure, a customer requirement, or a certification such as ISO 9001. It is not a casual walk-around: it follows a scope, uses a checklist tied to the standard, and produces documented findings that can be defended later.

Audits fall into two broad types. Internal audits are run by a company's own trained staff to catch gaps before anyone external does. External audits are run by a certification body, regulator, or client. In both cases the output is the same shape: each requirement is judged as a conformance or a non-conformance, and every non-conformance becomes owned work that has to be closed with evidence.

How a quality audit works in practice

A manufacturer schedules an internal audit against ISO 9001. The auditor works through a checklist mapped to the standard's clauses, sampling records, observing the process, and photographing evidence. Where a requirement is met, it is logged as a conformance. Where it is not, a non-conformance report is raised describing the gap and its severity.

Each non-conformance then drives a corrective action with an owner and a due date, and often a root cause step so the same gap does not recur. At the next audit, the auditor samples those closed actions to confirm they were genuinely resolved. This loop, from finding to corrective action to verified closure, is what makes an audit programme improve quality rather than just record its state.

How Inspectly360 handles quality audits

Inspectly360 delivers audit checklists mapped to your standard, with conditional logic that forces evidence on failed items and raises a non-conformance and corrective action automatically. Findings carry photos and timestamps, and closure requires evidence rather than a single tick, so an auditor's sample stands up.

Managers track open and overdue non-conformances by site and owner, and trend recurring findings to target root causes. See the Audit Management Software feature page for the full loop, and book a demo to map your internal audit programme.

Frequently Asked Questions

What is the difference between an internal and external quality audit?

An internal audit is run by a company's own trained staff to check its processes against a standard and catch gaps before anyone external does. An external audit is carried out by an independent party, such as a certification body, regulator, or major customer, and often decides whether a certificate is granted or kept. The mechanics are similar: both sample evidence against defined requirements and log conformances and non-conformances. The difference is independence and consequence. Internal audits are a chance to fix problems privately, which is why a strong internal programme is the best preparation for an external one, since the findings an external auditor would raise have already been closed.

What happens when a quality audit finds a non-conformance?

The non-conformance is recorded with a clear description of the gap, the requirement it breaches, evidence such as photos, and a severity rating. It then drives a corrective action with an owner and a due date, and for significant findings a root cause analysis so the underlying reason is addressed rather than just the symptom. Closure should require evidence, not a single checkbox, and high-risk items often need a second person to verify. At the next audit, the auditor samples those closed actions to confirm they held. This chain from finding to verified closure is exactly what an external auditor examines, so keeping it linked and evidenced is what makes the programme defensible.

How does a quality audit relate to ISO 9001?

ISO 9001 is a quality management standard, and auditing is one of its core requirements. Certified organisations must run internal audits on a planned schedule and are subject to external surveillance audits by their certification body. The audit checklist is typically mapped to the standard's clauses so every requirement is covered, and findings feed the corrective action and management review processes the standard also requires. In effect, quality audits are the mechanism by which an ISO 9001 system proves it is working. Software that ties audit checklists to the clauses, and links findings to tracked corrective actions, makes both the internal programme and the external audit far easier to evidence.

How often should quality audits be carried out?

Frequency depends on risk, the standard, and the maturity of the process being audited. Certification schemes usually set a minimum, such as covering the whole system at least once a year through a planned internal audit programme, with external surveillance audits on their own cycle. Higher-risk or less stable processes warrant more frequent checks, while stable ones can be audited less often. The schedule should be risk-based rather than uniform, focusing effort where problems are most likely or most serious. Consistent scheduling also builds a trend line over time, so recurring findings become visible and the programme can target the areas that keep failing rather than auditing everything at the same shallow cadence.

What makes audit findings hold up under scrutiny?

Findings hold up when they are specific, evidenced, and traceable. A finding should name the exact requirement breached, describe what was observed, and carry evidence such as a photo or a sampled record, rather than a vague note. It should then link to the corrective action taken and the proof of closure, so the whole chain from problem to resolution can be followed. Auditors challenge findings that rest on opinion or that close with no evidence, because those cannot be defended if disputed. Digital audit tools help by forcing evidence on failed items, timestamping records, and preserving an audit trail, so a finding raised months ago can still be shown exactly as it was captured.
