10 Reasons to Do Reliability

podcast episode with speaker Chris Jackson

Everyone ‘knows’ why we do reliability engineering … right? Customer experience. Organization reputation. Reduced warranty claims ten years from now. But these are boring reasons that really don’t motivate me to take reliability seriously now. Why should I invest so much time into an activity that benefits the ‘company’ or the ‘customer’ in the future but won’t make an immediate difference when my boss gives me a ‘gold star’ on my next performance appraisal? Besides, no one person is responsible for reliability, so any effort I invest in reliability will be ‘lost in the noise’ anyway. And, of course, reliability will increase the budget and schedule today. Right? [Read more…]

An Accelerated Life Testing Q&A

podcast episode with speaker Fred Schenkelberg

Over the past few months, we’ve received some questions about accelerated life testing. There are bound to be more questions as ALT can be confusing to plan, conduct, or interpret. Let’s get together and address your questions related to ALT. [Read more…]

Communicating as a Reliability Engineer

podcast episode with speaker Fred Schenkelberg

Creating a plan and generating information is part of reliability engineering, yet it’s not enough. To be a successful engineer, one must communicate well. This means we need to write, discuss, and present well. We are often called upon to examine failures and recommend solutions, examine a dataset and explain the finding, or conduct an experiment and detail the results. [Read more…]

What is ‘Supportability’ and How Does it Relate to Reliability?

podcast episode with speaker Chris Jackson

What is supportability? Is it working out how many spare parts you will need (and when)? No. Is it working out how many maintainers or technicians you will need to keep your system working? Still no. What about working out what tools these maintainers or technicians need? No again. But many people think that this is what ‘supportability’ is. ‘Supportability’ is actually a characteristic of your product or system. Is the ‘ability’ for it to be ‘supported.’ And this can mean different things in different scenarios. It is also not a ‘number.’ If you have two comparable systems, but one needs fewer spare parts, is easier to maintain, needs fewer tools, has lots of sensors that give plenty of warning for maintenance, and so on … then it might be more supportable. But the main thing you need to ‘think about’ regarding supportability is that because it is a characteristic of a product or system … it has to be baked INTO the design. Want to learn more about how to do this? Join us for this webinar.

Selecting a Reliability Method

podcast episode with speaker Fred Schenkelberg

A key element of reliability engineering is doing the right thing at the right time. When running an experiment or test, conducting an assessment, or performing an analysis, the method we use must fit the situation. Being busy does not add value; getting meaningful results does. [Read more…]

Where does the Bell Curve come from?

podcast episode with speaker Chris Jackson

Everyone has heard of the ‘bell curve.’ Sports show hosts, teachers, scientists, and a bunch of other people routinely use the term ‘bell curve’ to describe uncertainty. But do you know where it comes from? It is not just a ‘pretty shape’ that seems to work, It comes from a really cool physical phenomena that we find everywhere. So, the ‘bell curve’ naturally aligns with how our primitive human brain often tries to characterize or visualize uncertainty. The other really cool thing about the bell curve (and lots of other curves that look like bells) is that if we find it in our reliability data, it automatically tells us where to look in order to improve reliability. If you want a basic introduction to one of the most common statistical concepts with NO EQUATIONS … this is the webinar for you!

Building a Reliability Plan

podcast episode with speaker Fred Schenkelberg

This is an overview of the six steps to achieve high reliability from Carl and Fred’s book. Creating and executing a reliability plan that assists the team in designing, manufacturing, and supporting meeting reliability objectives takes effort. Let’s discuss the details of that effort so that you can focus on the critical steps. [Read more…]

What is Highly Accelerated Life Testing (HALT)?

podcast episode with speaker Chris Jackson

Some of you have heard of HALT (and I don’t mean someone asking you to stop). HALT is a very powerful form of testing that really helps us improve the robustness and reliability of new products. So what is HALT? HALT is a targeted test strategy to stress your amazing new product to (and beyond) its limits. Which means HALT will break your product (or prototype). Over and over again. Some people ask ‘so what … of course it was going to break when you pushed it that hard?’ But there is a method to this madness. And many organizations have used HALT to create amazing new products that are robust and reliable very quickly (with competitors struggling to understand why). Want to learn more? See you at this webinar!

The State of Reliability Education

podcast episode with speaker Fred Schenkelberg

We have many options to learn reliability engineering—books, magazines, newsletters, conferences, seminars, etc. We have options. Some options are better than others, depending on what you want to know. Likewise, some options are better than others, depending on what you want to share.

What is Accelerated Life Testing or ALT?

podcast episode with speaker Chris Jackson

Sounds simple … right? We simply test faster! Great! But what does this get us? Many organizations are faced with a dilemma when it comes to testing to MEASURE reliability. If we test an amazing new product in ‘at use’ conditions, it might take many years before it will fail. This is time we simply don’t have when it comes to product development. So, how do we test faster? One of the more obvious answers is to increase the stress. Turn the temperature up. Increase the vibration. Use more voltage. But how do we get this right? How can we know that (for example) one week of accelerated testing is equivalent to 10 years of actual use? This webinar will help introduce you to the idea of Accelerated Life Testing, or ALT, to help you and your organization make reliability testing a reality.

Design for Reliability – Stressors

podcast episode with speaker Michael Pfeifer

Any product is a collection of materials that have been engineered, shaped, and modified to become components and joints (e.g., weld and braze joints). The materials can degrade due to exposure to use conditions – steel screws corrode when exposed to water, some plastics become brittle when exposed to sunlight, and coatings on surfaces can wear away.

Components and joints will stop functioning as required if their materials degrade too much. This is a problem if it reduces or loses product performance before the end of a product’s expected life.

Identifying the conditions to which materials are exposed and selecting materials that can withstand the exposure are critical parts of designing products that have good reliability.

During this event, I will discuss identifying the conditions that can cause materials to degrade. [Read more…]

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.

Reliability Occurs at the Point of Decision

podcast episode with speaker Fred Schenkelberg

The reliability performance of a product or system exists because the decisions that occur during the creation of the product establish how well an item will survive without failure. The choice of material, finish, or technologies, along with all the other decisions involved, define how well a product performs, including its reliability. [Read more…]

What is the Weibull Distribution?

podcast episode with speaker Chris Jackson

Whether new to reliability or a veteran, you have probably heard about the Weibull distribution. It has almost mythical status amongst those who conduct reliability data analysis … or in other words – turning a jumble of dots (data points) into information that actually means something. So why do we ‘worship’ the Weibull distribution? What is so special about it? Whether you have been doing this for a long time or five minutes, you will get something out of this webinar that looks at one of the most popular tools for reliability analysis.

Focus on Failure Mechanisms

podcast episode with speaker Fred Schenkelberg

In my opinion, as I do not know if this is true or not, every product or system failure has a cause. Causes are not exactly the same as what we call ‘failure mechanisms’, yet they are related in many cases. One more term to consider is ‘failure mode’, which refers to the symptoms or results of a failure. [Read more…]
