What’s the difference between an Audit and an Assessment?
An audit is an examination of results to verify their accuracy by someone other than the person responsible for producing them. An assessment is a judgement made about the results.
Assessment goes further than an audit as it involves the determination of actions necessary to make the assessed entity compliant. Therefore, in assessing opportunities for improvement, you would not only identify such opportunities but also make some judgement on the benefits to be gained and the actions to be taken to realize the improvements.
