Reliability predictions:

:* '''Help assess the effect of product reliability on the maintenance activity and on the quantity of spare units required for acceptable field performance of any particular system.''' For example, predictions of the frequency of unit level maintenance actions can be obtained. Reliability prediction can be used to size spare populations.

:* '''Provide necessary input to system-level reliability models.''' System-level reliability models can subsequently be used to predict, for example, frequency of system outages in [[Steady state (electronics)|steady-state]], frequency of system outages during early life, expected [[downtime]] per year, and system availability. <ref>{{cite web| url=https://www.tronicszone.com/ | title= Reliability Prediction| accessdate = 13 July 2015}}</ref>

:* '''Provide necessary input to unit and system-level life cycle cost analyses.''' [[Whole-life cost|Life cycle cost studies]] determine the cost of a product over its entire life. Therefore, how often a unit will have to be replaced needs to be known. Inputs to this process include unit and system failure rates. This includes how often units and systems fail during the first year of operation as well as in later years.

:* '''Assist in deciding which product to purchase from a list of competing products.''' As a result, it is essential that reliability predictions be based on a common procedure.
