Quality assurance (QA) is the activity of providing, through an audit process, the evidence needed to establish that all activity is being conducted in accordance with the applicable requirements, standards and procedures. It should be carried out by a unit which is fully independent of the executive management who have responsibility for delivering the function being assessed. There should be appropriate means to ensure that response to findings is monitored and documented.
