quality assurance is a general concept covering the way in which a business is organized so that the quality of the product is assured at all stages. As applied to a wine business, good quality assurance will ensure that the original potential of the grapes and wine is not lost on the way to the bottle. Quality assurance is the totality of all the management actions and procedures that set out to achieve this high standard, and therefore incorporates quality control.
An internationally recognized standard of quality management is ISO 9001:2008. This standard imposes a discipline that demands a uniformity of action throughout the business every time, all of the time.
