Paths to Learning Reliability

Abstract

Chris and Fred discuss about how to learn to be a reliability engineer. And ‘learn’ means different things. It could be experiential learning. It could be academic learning. It could be instructional or ‘mentorship’ learning. And you tend to be a particular type of a reliability engineer based on how you learn about reliability. But there are pros and cons for each approach. And sometimes, you just ‘stumble’ into a learning process when a company sponsors you to become their expert. There are so many different ways to learn about reliability. This podcast talks about some of the more common ways, and how each tailors to a certain learning path.

Introducing Accendo Reliability 2020

Abstract

Chris and Fred discuss the new challenges of reliability in the upcoming years. Accendo was originally setup to help reliability professionals in an objective and broad forum. And this appeared to fill a void. Trade magazines are over-bearing, with sponsor adds replacing well thought-out articles. Professional societies are becoming less and less relevant (but more expensive). And Accendo lists ‘competitor’ programs, blogs and articles where other organizations strictly focus on their products, courses, books and so on. So Accendo has become the only ‘one stop shop’ for the reliability engineering community who want to develop their skills.

Professional Tidier Marie Kondo … and How we Can Do the Same in Reliability

The Definition of Reliability and Quality

Abstract

Chris and Adam discuss how the definitions of ‘reliability’ and ‘quality’ align … or differ. What are the differences? Do these differences matter for all applications? Is there merit in arguing that there is a difference? Well … the answer to each question is both ‘yes’ and ‘no.’ Confused? Perhaps listening to this podcast might help. Because we should only use definitions that help us and our organization. In a way, using a definition that makes the most sense to your organization is not only acceptable, it is necessary. And many organizations have failed because they have never understood these differences.

HALT Versus ALT

Abstract

Chris and Adam discussing HALT and ALT. What are these? HALT stands for Highly Accelerated Life Testing. ALT stands for Accelerated Life Testing. They sound very similar. But they are not. HALT is a destructive test regime. In fact, a good HALT plan will involve that product failing many times. This is done by subjecting the product to stresses (vibration, thermal cycling et cetera) well beyond actual operating stresses. Some of the failures this creates will not be relevant. That is, they will simply never occur when the product is used ‘normally.’ But many failures are relevant. And by undertaking HALT, we now have a good idea of which failure mechanisms and modes are likely to occur when it is used normally. And this information is incredibly valuable to a design team. ALT on the other hand starts with a failure mechanism you know about. And in a short period of time, you can predict how long that failure mechanism will cause your product to fail when used normally.

Still confused? Well listen to this podcast.

Reliability Security Blankets

Abstract

Chris and Adam discuss ‘reliability security blankets.’ What are these? These are things that people or organizations do to give the illusion of ‘achieving something to do with reliability’ primarily to make them ‘feel’ better. Reliability security blankets tend to have little positive benefit. When we are focused on a feeling of ‘reliability goodness’ we quickly try to find the easiest way to get that feeling. Which leads us to standard or outdated methods, non-critical thinking, or (worst case) tests that are structured to ensure a system or product passes. Resources are sucked away from good reliability activities to create these reliability security blankets. If you think this applies to your organization, listen to this podcast.

A Brief History of Reliability

Abstract

Chris and Adam discuss a ‘brief history of reliability.’ There are many significant milestones in the history of mankind. The dawn of the iron age meant that instead of having tools that lasted a matter of days, humans could (in a very short period of time) create tools that lasted several human lifetimes. The Industrial Revolution of the 1800s taught us that we could ‘over-engineer’ a device so that it would last longer than its ‘useful life.’ There are many more different milestones and events that have defined reliability over time. And these have shaped how we deal with product and device reliability today. Learn more by listening to this podcast. ᐅ Play Episode

Dealing with the Occurrence of Failure

Abstract

Chris and Fred discussing how different organizations deal with failures. Failures are a ‘bad’ thing in that a system doesn’t do what you hoped it would. But what about failures that occur during the design or production process? This is different. If you have scope to improve your system, then failures that you can analyze in a laboratory or test bed are invaluable. They, more than any other event, will help you understand the vulnerabilities of your system. And you must actively seek vulnerability to improve reliability. But if you are looking for failures, you must first admit that your system is vulnerable. And that is difficult for many people to do.

The Recent Soyuz Rocket Failure and What We Can Learn

Abstract

Chris and Fred discussing the recent Russian Soyuz rocket failure. With the retirement of NASA’s space shuttle fleet, the Soyuz rocket and spacecraft are now the only viable way to launch humans into space. The 1960s Soyuz rocket propels the 1960s Soyuz spacecraft into orbit … and to be clear it is only the rocket that failed. The Soyuz spacecraft successfully aborted the launch keep the crew safe. The Soyuz rocket has long been the yardstick of rocket safety – it easily has the most impressive reliability track record. But should this recent failure change that perception? And how can the Soyuz system still be operating when other programs have come and gone, primarily due to safety and reliability? This podcast attempts to answer some of these questions.

The Russian Concorde – How Not to Design Reliable Aircraft

Abstract

Chris and Fred discussing the little known Tupolev Tu-144 or the Russian Concorde. It was developed as a direct competitor to the Anglo-French Concorde, and was also the first commercial aircraft to fly at a speed of Mach 2. It even looks like the Concorde. But there is a reason you have not heard of it. Yup … reliability. And there is much to learn. In fact, Chris decided to write an article about it which can be read here.
