reliability

the extent to which a product fulfils its function over a period of time.

The reliability of a product depends upon its design characteristics, the quality of materials and components embodied within it and the care with which it is made and assembled.

A product's reliability is an important part of its performance in use and thus affects the appeal of the product to customers and the likelihood of their buying it. See BRAND LOYALTY. See QUALITY CONTROL, FAILURE RATE CURVE, PARALLEL SYSTEM.
