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!

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.

What does this title mean? Chris and Fred discuss how some vendors make ‘startling’ claims regarding reliability from some small amounts of test data. So where does this 60th percentile some of us hear from time to time come from?

We have a reliability target for our system. But we’re not meeting it.
To avoid this scenario, what is something we can do in early development?
When we’re figuring out our concept, we can better learn about our options. We can work with Reliability Engineers to understand what we know, the risk in what we don’t know, and to prioritize reliability of the modules to be able to meet the reliability of our whole system.
We talk about using reliability allocation to help us choose reliability goals for modules of our product design. And we talk about its limitations.

Chris and Fred discuss whether you want to lay blame (i.e. sue) or improve reliability? Don’t be confused … accountability is important. But that doesn’t replace everyone ‘owning’ the end result.

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.
