Quality management ensures that an organization, product or service is consistent. It has four main components: quality planning, quality control, quality assurance and quality improvement. Quality management is focused not only on product and service 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.
Quality management is a recent phenomenon but very important for an organization. Advanced civilizations that supported the arts and crafts allowed clients to choose goods meeting higher quality standards rather than normal goods. In societies where arts and crafts are the responsibility of master craftsmen or artists, these masters would lead their studios and train and supervise others. The importance of craftsmen diminished as mass production and repetitive work practices were instituted. The aim was to produce large numbers of the same goods.
