Reliability has sometimes been classified as "how quality changes over time." The higher the correlation value meaning that the instrument is more reliable. Finally, we make a plea for a return to terminology for ensuring rigor that is used by mainstream science. Praktische Beispielsätze. Simply improving the inherent reliability does not always ensure that the operational reliability improves (unless the plant is modified so that the overall system continues to function satisfactorily when a failure occurs - eg by fitting standby equipment). For instance, a cloud solution may be available with an SLA commitment of 99.999 percent, but vulnerabilities to sophisticated cyber-attacks may cause IT outages beyond the control of the vendor. To consider why information should be assessed 2. 16 Approved for Public Release, Distribution Unlimited, GDLS approved, log 2008-04, dated 02/11/08.
