What is a 'Fault Tree'?
What is a ‘Fault Tree’?
podcast episode with speaker Chris Jackson
If you have spent any time doing reliability engineering stuff, you will probably have heard of this thing called a ‘fault tree.’ You may have even used fault trees a lot. But it is amazing how many different reliability engineers have different ideas about how to use a fault tree best. Some think fault trees are strictly used to work out which combinations of components need to fail for the system to fail (system reliability modeling). Others think fault trees are really useful for helping us work out what the causes of failure are (root cause analysis). Both people are right. So why do we get these competing schools of thought? Join us for this webinar to learn more about how fault trees can help you … regardless of what you are trying to achieve.

What do you see in a 'Probability' Plot?
What do you see in a ‘Probability’ Plot?
podcast episode with speaker Chris Jackson
Some of you might have heard about probability plots like Weibull plots. Some of you might not. A Weibull plot is a really useful way of quickly looking' at data and being able to see' really useful things. This could be seeing that a system’s failure rate is decreasing over time which usually means there are manufacturing defects. It could be seeing that the rate of failure of a system is increasing over time which means the system is accumulating damage or wearing out. And lots of other things. So, let's look at a different sort of probability' plot and see what we can work out from it. And that means working out what we need to do to improve reliability. Join this webinar if you want to learn how to see really useful things in lines that you might not have appreciated in the past.

Confidence in Reliability
Confidence in Reliability
podcast episode with speaker Chris Jackson
Reliability is a measure of your product or system. Confidence is a measure of you. But we often forget this. We often subject our new product, system, or service to test after test until it reaches this thing called required statistical confidence.' But this is often an illusion, which is great! Because if statistical confidence is often not real' confidence, then we don't always have to resort to statistics to get confidence. In fact, those of us who exclusively rely on statistics are usually those who lack confidence in the product, system or service and need a security blanket to make them feel OK. This webinar talks about confidence from the perspective of the process owner.' The design team lead. The CTO. The junior engineer. And how you can get a much healthier version of confidence through the way we design and produce our things' so that when it comes time to test we are (justifiably) supremely confident that we will absolutely dominate whatever statistical testing hurdle can be thrown our way. And this sometimes means we don't need to deal with statistics at all!

Reliability and Maintenance
Reliability and Maintenance
podcast episode with speaker Fred Schenkelberg
Both reliability and maintenance activities work to reduce failures and downtime. Perfect reliability of a system would eliminate the need for maintenance. Perfect maintenance would keep even poorly designed (reliability-wise) operating.
Together, the work of reliability and maintenance professionals can achieve more than each team working separately. Each brings a set of insights and skills to the conversation. Working together means improving the design of a system so it's easier to maintain. It also means the maintenance teams’ day-to-day observations provide meaningful information to the reliability team.
Let's explore how these two related fields are bound together in many ways. What works well, and what could work better?

OK we have all been there. We have all sat in some statistical presentation or read a document containing mathematical symbols and statistical hieroglyphics we don't understand. And we pretend we do understand so that we don't embarrass ourselves. The people we don't want to embarrass ourselves in front of usually also pretend to understand those symbols and hieroglyphics. This webinar is a light (re)introduction to common mathematical symbols used in many engineering scenarios including reliability.
They can be really simple to understand if you only know how. So if you see all manners of Greek letters or have to talk to someone who always uses the term sigma' and you have no idea what they mean then this webinar is for you.

How to take the Guess Work out of Expert Judgment
How to Take the Guess Work out of Expert Judgment
podcast episode with speaker Chris Jackson
Most humans can be quite technically minded. And sometimes we aren't. Sometimes, we expect every drug or medical procedure to be checked, approved, validated, and tested on other people (et cetera) before subjecting ourselves to whatever our doctor suggests. At other times, we spend lots of money at casinos (note that I said spend' and not invest' or win'). When it comes to reliability, we can sometimes be too technically minded. A reliability number' might not exist until our product has undergone exhaustive testing. Which can often be two years too late to do anything about if it turns out it doesn't meet all our reliability dreams. So what can we do? Well why spend money trying to generate information (through lengthy tests) when you can use the information stored in everyone's brain? The most common answer (even if we don't want to admit it) is that this sounds like guesswork. And guesswork can sound unprofessional. Or it’s just wrong. But there are ways you can suck out information from a group of experts in a quantifiable and remarkably accurate way. Want to learn more? This webinar introduces you to some of the concepts that might interest you.

podcast episode with speaker Fred Schenkelberg
When fitting a line or curve to data, it's a model. When modeling, it is worth remembering the George Box quote, Essentially all models are wrong, but some are useful. Yet, how do we separate a useful model from one that isn't useful? One step in finding a helpful regression model is to consider the residuals. BTW: Weibull analysis is another term for regression analysis.
Residuals in regression analysis are the differences between the data and the model-predicted values. When the regression fits' the data, the residuals should represent the naturally occurring experimental (measurement) errors. These should be well-behaved differences that tend to fit a normal distribution centered on zero.
Let's explore what residuals are, where they come from, and how to evaluate them to detect whether the fitted line (model) is adequate. Not checking or using a poor model is a recipe for major errors when making decisions. Checking residuals is one step to validating a model, yet it's quick and easy to accomplish.
