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.

Step 13: Determine from the ROCOF plot whether the point process is homogeneous, or alternatively, whether there is evidence of reliability growth or deterioration.
The appropriate methodology for the assessment of reliability trends together with the necessary calculations for both the ROCOF curves and the Laplace test for such systems have been detailed in this paper.
Constant ROCOF implies that the times between successive failures are identically distributed.
