Definitions[]
Data[]
Reliability means that
| “ | data are reasonably complete and accurate, meet your intended purposes, and are not subject to inappropriate alteration.[1] | ” |
General[]
Reliability is "the property of leading to consistent intended behaviour and results."[2]
Service[]
Reliability is
| “ | the probability that a service will perform its required function for a specified period of time under stated conditions.[3] | ” |
System[]
Reliability is
| “ | the likelihood that a system will perform its intended function within the context it was designed to operate within.[4] | ” |
| “ | [t]he ability of a system or component to perform its required functions under stated conditions for a specified period of time. It is often measured as a probability of failure or a measure of availability.[5] | ” |
| “ | the ability of a system and its parts to perform its mission without failure degradation, or demand on the support system.[6] | ” |
| “ | the ability of a system to perform and maintain its functions in routine circumstances as well as hostile or unexpected circumstances.[7] | ” |
Overview (Data)[]
A decision that computer-processed data are reliable does not necessarily mean that the data are error-free. Errors are considered acceptable in this circumstance: You have assessed the associated risk and conclude that the errors are not substantial enough to cause a reasonable person, aware of the errors, to doubt a finding, conclusion, or recommendation based on the data.
Overview (Service)[]
Reliability focuses on a system's ability to perform as intended, despite apparently random hardware and software failures.
