Checklist: prepare your ISO 9001:2015 internal audit

Before your ISO 9001:2015 internal audit, verify twelve points: scope defined, impartial auditors, current policy and objectives, risks up to date, controlled documentation, KPIs with data, previous nonconformities closed, complaints analyzed, competence backed by evidence, suppliers evaluated, management review completed, and corrective actions with an owner and a date.

• ☐ Audit scope and criteria defined and communicated
• ☐ Audit program approved and auditors free of conflicts of interest
• ☐ Quality policy and objectives current and known by staff
• ☐ Risk and opportunity matrix up to date
• ☐ Documented information controlled (versions, access, obsolete documents withdrawn)
• ☐ Process KPIs with data from the last 12 months
• ☐ Previous nonconformities closed with evidence of effectiveness
• ☐ Customer complaints logged with root-cause analysis
• ☐ Personnel competence backed by evidence (this is where your LMS shines: certificates and grades)
• ☐ Critical suppliers evaluated
• ☐ Management review for the period held, with agreements and follow-up
• ☐ Corrective action plan with owners and dates
