Our Process
How It Works
A proven three-stage audit methodology. TQS conducts the audits — certification is issued by QRS (Quality Register System).
Gap Analysis
Our auditors evaluate your existing systems against ISO requirements, pinpointing exactly where you stand and identifying non-conformities that must be addressed before certification.
Certification Audit
TQS conducts the Stage 1 documentation audit followed by the Stage 2 on-site audit, examining your management system in full and verifying conformity to the standard.
Certify & Maintain
Upon successful audit completion, your internationally recognised certificate is issued by QRS (Quality Register System). TQS then performs ongoing surveillance and re-certification audits to keep your certification active.
