The reliability growth process, applied to a complex system under development, involves surfacing failure modes, analyzing the modes and their causes, and implementing corrective actions (fixes) to detected any problems.

Accurate reliability prediction and control play an important role in the product cost-effectiveness and profitability.
Costs of a product service within the warranty period or under the service contract are the major expense and significant pricing factor. Proper spare part stocking and support personnel hiring and training also depend upon a good reliability predictions. On the other hand, missing reliability targets may invoke contractual penalties and even loss of business.
