Quality audit
A quality audit is a high level check, carried out by independent personnel in order to ensure that the project’s quality performance standards are being met
Most QA and QC systems would be subject to internal and external audit.
In a university for example,
student marks are assessed and checked by internal members of staff, and
all the results and recommendations are then subject to check by external examiners.
Some kind of audit process is essential if any QA or QC system is to operate effectively.
