ISO Internal Audit and Gap Assessment Services

A useful audit goes beyond confirming that documents exist. Vertex audits test implementation, records, process effectiveness and the quality of corrective action.

Audit scopes

  • Internal management-system audits
  • Gap assessments
  • Supplier and vendor audits
  • Compliance-focused reviews
  • Pre-certification readiness audits
  • Corrective-action follow-up
  • Integrated audits across multiple standards

Audit approach

  1. Agree scope, criteria and sampling.
  2. Review relevant documented information.
  3. Interview process owners and inspect records.
  4. Identify nonconformities, observations and improvement opportunities.
  5. Report evidence clearly.
  6. Track corrective actions and verify effectiveness where included.

These services are not the independent certification audit.
