If reliability engineering costs you money, then you are doing it wrong. But chances are that someone you work for looks at reliability engineering as a black hole of costs. This needs to stop!
Reliability engineering is about creating value. Or money. Or more missions. Or safety. But it would help if you showed how this will happen. [Read more…]

Have you ever wondered if your servicing intervals are ‘good’? Do you know what ‘good’ is? Are you servicing too much or too little? What happens if you service too much? Do you use some basic equations in textbooks and plug in numbers that seem too simple and basic, AND you don’t understand them (all at the same time)?
If you have asked yourselves any of these questions, then this is the webinar for you. A really simple, never done this before. Please join me in the discussion on what it actually means to optimize servicing intervals. [Read more…]
This is our fifth article about the 3 ways to do reliability allocation. We have been taken on a journey through the reliability design cycle, key steps for reliability allocation, allocation factors used to get these goals and key pitfalls. Now we finish off our conversation by looking at a few variations and applications. Allocating MTBF (… though we recommend against it), allocating availability, allocating maintainability (… another thing we recommend against) and allocating for different system reliability goals.
If you want to finish off your understanding of reliability allocation – read this!
Chris and Fred discuss what a leader, champion and manager are. Many textbooks, guidebooks and so-called ‘domain experts’ tell us what (for example) a ‘reliability leader’ is. In some cases the ‘reliability leader’ is someone who has little influence, and is more of an ad hoc ‘doer.’ Not a leader. Why is this? Listen to this podcast to hear more about this?

Chris and Fred discuss assumptions – and when you need to check if they are valid. And if you do need to … how do you check these assumptions? Reliability (and all sorts of other engineers) need to study variation and variance. We are often interested in when the first ‘5 percent’ of things will fail. So assumptions on the underlying failure (or random) process are crucial. Sound familiar? Listen to this podcast to learn more.

This is our fourth article about the 3 ways to do reliability allocation. The first three articles describe the reliability design cycle and how reliability allocation is a part of this cycle. Our last article focused on what options you, as a design team leader, have at your disposal when you realize that your components aren’t on track to meet their allocated goals (or doing something!) Now we talk about working out what these allocated goals are. And how to get them. And don’t worry – it is much easier than you probably think!

Ok. They say there are lies, damn lies, and statistics. At the heart of statistics are these intimidating functions like ‘probability density functions’ and ‘cumulative distribution functions.’
They mean something – but are practically useless unless they help inform a decision. And we, as engineers, are supposed to know what these functions mean. But have you ever sat in a meeting or presentation where you realized some gaps in your knowledge? … or perhaps you felt like you were given too many charts but not enough help to make your decision?
If you want a really easy introduction or review of these functions – then check out this webinar!

Chris and Fred discuss how we need to estimate monthly failure rates of a product. Like when bosses or directors want to know what the ‘failure’ or ‘return’ rate of a product is this month. But is this useful? How do we account for the number of products we have shipped? How old are the products when they fail? And how do we learn from these numbers? Can we even find a number?

This is our third article about the 3 ways to do reliability allocation. In the first article, we set the scene. We talked about the reliability design cycle that needs to be implemented to make sure what we do will actually work. Will actually matter. In the second article, we cover the six steps of reliability allocation. In this article, we go through the six steps of reliability allocation.
You should have already read these articles – and if you haven’t please do! Once we have our reliability design cycle up and running, there are six key steps to making reliability allocation happen. And this article is about the sixth step – doing something!

Chris and Fred continue the discussion on the history of reliability engineering. The discussion started with Chris and Adam (you can click here to listen to it) and kept going with Chris and Carl (and you can click here to listen to it). Between all of them, they came up with 8 reliability engineering epochs. Now it is Fred’s turn to work out what has been missed, and what all of this means what reliability engineering looks like in the future.

Chris and Carl continue the discussion on the history of reliability engineering. The discussion that started with Chris and Adam (you can click here to listen to it). In the short time they had to talk about it, they came up with 6 reliability engineering epochs. Now Carl is going to see if there is anything to add – and importantly – anything to learn.

Chris and Adam discuss the history of reliability engineering. Everyone (customer, manufacturer, builder) has different ideas of what reliability is. And this has changed throughout history. Perhaps we can learn something from what reliability engineering has also changed throughout history. As they say – those who don’t learn from history are destined to repeat it. This is the first of three podcasts that look at the history of reliability for this purpose: seeing what we can learn to help reliability engineering now and tomorrow.

This is our second article about the 3 ways to do reliability allocation. In the first article, we set the scene. We talked about the reliability design cycle that needs to be implemented to make sure what we do will actually work. Will actually matter. In this article, we go through the six steps of reliability allocation. You need to do the preparation work first. But … we are all about keeping it simple. Making it exhaustive and complicated means you are wasting your time.

Chris and Joe Bell from G2OPs talk about systems engineering and how it relates to reliability engineering. Joe and his team focus on Model Based Systems Engineering (MBSE) and was hoping to learn more about reliability and MBSE at the 2020 Reliability and Maintainability Symposium (RAMS). Was RAMS successful in helping out Joe? Listen to this podcast to learn more.
