What is meant by the term Quality Assurance?
   
Quality Assurance is the term used by manufacturers, to describe the ‘administrative system’ put in place, to ensure that quality control (checks carried out by workers on a product / component) can be carried out effectively. Quality Assurance should ensure that staff training, administrative procedures and quality monitoring of the product at various stages of manufacture, is to the highest standard. Customer surveys will be carried out to ensure customer satisfaction, all part of quality assurance. Furthermore, the British Kite Mark and European CE Mark, may be applied to products that satisfy British and European quality standards.
 
What is meant by Quality Control?
 
Quality Control refers to the checks carried out on a product by workers, during stages of its manufacture. These checks may include, simply ensuring that components are positioned correctly, or that they are the correct type and size. A final quality check should include, testing the product to ensure it is to the correct standard, before it is distributed to the retailer / customer. A combination of visual checks and automated checks (by sensors and computers) are usually carried out.
 
Example: A guitar is manufactured for a customer. Many stages are involved in the making of the guitar. Four of the stages of manufacture are seen below. Each of the stages includes a quality check, to ensure that substandard components are rejected and that only accurately made components are assembled, to form the final guitar.
 
 
 
 
How do Quality Control and Quality Assurance differ?
 
Quality Assurance is the system of administrative procedures, set up to ensure that effective quality control on the production line can be carried out. This includes the training of staff, so that they know how to recognise substandard work / products.

Quality Control is, carrying out regular checks on the production line, as a product is manufactured. Substandard components / products are rejected, ensuring that only products of the correct standard are distributed to the customer / retailer.
