Why Redundant Systems Aren’t Always Redundant
podcast episode with speaker Chris Jackson
Redundancy has continually proven not always to be redundant. Whether the Fukushima nuclear power plant or United Airlines Flight 232, additional components or subsystems that are supposed to take over when others have failed don’t always work. Why is that? There are quite a few reasons … many of which we already know about. But time and time again, otherwise, smart people choose to ignore what we know about how to REALLY make things redundant in order to save costs, save thinking, or otherwise confuse efforts with outcomes. In this webinar, we will look at how redundancy is described in textbooks … and how it can go wrong in the real world.
This Accendo Reliability webinar was originally broadcast on 22 November 2022.

Reliability Apportionment and How to Do It
Reliability apportionment is a power tool to enable your team to make decisions while fully considering the reliability impact.

Fundamentals of RBD
Reliability Block Diagrams are a useful and simple tool to encourage reliability discussions and improved decisions.

Fundamentals of Physics of Failure
Let's consider physics of failure (PoF) models, how to use them, plus how to create them, as a central element of your reliability program.

Fundamentals of Monte Carlo Analysis
The Monte Carlo method is a relatively simple process that permits you to create models that include the naturally occurring variability.

3 Ways to Do Reliability Allocation
Having a reliability target for your product is great. But how does that help all the little design teams? Use subgroup targets.

Reliability Life Models
Failure is a random process. Which means we can't predict with absolute certainty when something will fail. Enter 'reliability life models.'

Why Redundant Systems Aren’t Always Redundant
Redundancy has continually proven to not always be redundant. Let's explore a few reasons this occurs. And, how to judge your system.
