insights INSIGHT
Embrace Randomness in Failures
Failure times of identical components vary due to invisible manufacturing differences.
This randomness is natural and must be embraced in reliability engineering.
insights INSIGHT
Probability and Reliability Curves
Probability density and reliability curves visualize failure likelihood and survival over time.
These curves represent the same info but aid different types of analysis.
insights INSIGHT
Mean Time to Failure Misleading
Mean time to failure balances the probability density curve but doesn't reflect reliability accurately.
Different failure mechanisms produce distinct signature curves despite sharing the same mean.

Weibull probability plotting is perhaps the most widespread data analysis tool used in reliability and quality engineering. Some of you might have used it. Some of you might know that it magically' creates straight lines out of failure data, and the slope and location of that straight line sort of means something. Good reliability engineers know what these straight lines mean, what it means if the lines aren't straight, can do things like look at these lines to optimize maintenance regimes, work out if we quality control issues (or not), and lots of other things. And the good news is if you know how to use Weibull probability plotting you don't need to use complex equations! This Accendo Reliability webinar was originally broadcast on 22 April 2025.
