Limitations of Reliability Prediction Models

 Reliability prediction models provide MTBF point estimates. Model inputs include base
component failure rates, environmental, quality, and stress factors.

Base failure rates use failure data from multiple sources, including industry field data, research
lab test results, and government labs.
 Environmental, quality, and stress factors may differ from field conditions.
 Predictions assume a constant failure rate which does not account for failures due to early life
quality issues or wear-out phenomena.

General Prediction Methodology

 VIDYO's default prediction methodology is Telcordia SR332, Reliability Prediction.
