A Quality Assurance Certificate is issued when an audit has been conducted in accordance with the International Standard. This may be a part of a Quality Management System or of an integrated system with a number of standards, that has been the trend recently.
As oppose to having three manuals, they can now be merged into one, reducing the workload on staff and improve performance in the operations of the company. The Quality Assurance Certificate is valid for twelve months until another audit is conducted to ensure that the items are addressed as part of the standard.
Quality Management Systems does not aim to assure 'good quality' by the more fit for purpose definition, but rather to ensure that an organisation or product is consistent. This can be considered to have four main components: Quality Planning, Quality Control, Assurance and Quality Improvement. Quality management is focused not only on product service and quality, but also the means to achieve it.
Quality Management therefore uses Quality Assurance and control of processes as well as products to achieve more consistent Quality.
