Failure is a random process. But just because something is random, doesn't mean it isn't predictable. A lot of reliability engineering comes down to being able to understand how something fails. And this understanding needs to extend (in some cases) to being able to predict when a certain fraction of things will fail, or how many spares you need. And this means that you need a 'reliability life model.' If you have never heard of them before, or if you want a refresher, this webinar is for you.
