internalaudit_skill

Overview

This skill supports planning and executing an IATF 16949 internal audit programme across QMS, process, product, and layered process audits. It helps create audit schedules and checklists, document findings, classify nonconformances, and manage corrective actions to closure. Use it to align audits with clause requirements and customer-specific expectations.

How this skill works

The skill guides audit planning, builds clause- and process-based checklists, and structures evidence collection during on-site audits. It generates audit reports and findings with classification (Major, Minor, OFI) and produces corrective action workflows including containment, root-cause analysis, implementation, and verification timelines. It integrates with manufacturing process and A3 root-cause tools for technical checks and structured problem solving.

When to use it

• Plan or update the annual internal audit programme
• Create or tailor audit checklists for QMS, process, product, or LPA
• Conduct on-site process, product, or QMS audits
• Document audit findings, classify NCRs, or record OFIs
• Prepare corrective action plans and verification schedules
• Prepare for IATF 16949 certification or surveillance audits

Best practices

• Build a risk-based annual schedule covering all QMS processes within the audit cycle
• Use clause-based checklists for QMS audits and turtle diagrams for process audits
• Keep LPA checklists short and consistent across levels for rapid verification
• Collect objective evidence—records, observations, and interviews—and avoid opinion-only findings
• Classify findings clearly and assign containment, root cause, action owner, and verification date
• Verify corrective actions within defined timelines and track trends for systemic issues

Example use cases

• Generate an audit plan that covers all processes with frequency based on risk and past performance
• Create a process audit checklist using the turtle diagram prompts (inputs, controls, equipment, competence, outputs)
• Perform a product audit sampling per the Control Plan and record measurement evidence
• Execute a layered process audit with daily supervisor checks and monthly managerial review
• Produce an audit report with Major/Minor/OFI counts and detailed finding entries for corrective action
