Rework and complaints can consume time and resources, but a claimed saving needs evidence. Certification itself does not establish a financial return or explain why a particular business result changed.
Questions to follow in an audit
- Which costs are included in the quality measure?
- How are rework and complaint records linked to those costs?
- Who checks whether an improvement remains effective?
Connect the records with practice
Compare a recorded problem, the action taken, the measurement method and subsequent results, including other changes that may affect the comparison.
These are illustrative audit trails, not findings about a named organisation, technical instructions or a guarantee of a particular result. The appropriate evidence depends on the activities, risks and agreed scope. The organisation remains responsible for its operations and legal obligations.
