Three stages in the development of quality:

Quality Control

It is the traditional method of maintain quality and involves detecting and cutting out components or final products which fall below set standards. This process takes place after these products have been produced. Quality control is carried out by Quality control department which inspects and tests the finished products. It may involve considerable waste as defect products are scrapped.

Quality Assurance

It occurs both during and after the event, and is concerned with trying to stop faults from happening in the first place. The business will make sure quality standards are set and then it will apply these quality standards in the production process. Quality assurance is the responsibility of the workforce, working in cells or teams, rather than an inspector.

Total Quality management (TQM)

Total Quality Management, TQM, is a method by which management and employees can become involved in the continuous improvement of the production of goods and services. It is a combination of quality and management tools aimed at increasing business and reducing losses due to wasteful practices.
