Announcements & Reminders
Greg Hutchins is starting a monthly webinar series under the Accendo Reliability webinar program. The first event is titled?Four Ways to Manage Supplier Risk , scheduled for June 6th.
Stay safe, stay flexible, and stay resilient.
Cheers,

PS: Since reading the Hitchhikers Guide to the Galaxy series of books, the number 42 has been a favorite number of mine. (and the phrase "Don't Panic," of course.)

Chris and Fred discuss a question by a listener regarding ALT or Accelerate Life Test design.
Chris and Fred discuss how software packages help us do reliability stuff … and how we trust them to do the right thing.
Statistical tools are a good way for us to make decisions and the results can act as proof for us. But, there’s a practical, engineering side to results, too. We need to evaluate the statistical significance along with the practical significance.
In this episode I discuss the state of steel metallurgy knowledge and the things this knowledge have enabled.
Sandeep Jadhav explains the concept of the Null alternate hypothesis as well as the producer’s risk or as he likes to call it, an overreaction in the simplest way possible.
My guest today is Dr. James Whitfield, an associate professor of physics at Dartmouth and author of Quantum Technology, A Theoretical Overview of the Possibilities.

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 … than 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. Listen to learn more about how to do this!

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.

If you have never heard of Reliability Centered Maintenance (RCM) then you need to know it is one of the most wonderful approaches to getting an optimal maintenance regime … if done well. And there are plenty of reasons it is not done well.
RCMs need to be taken seriously by organizations, resourced and trained for. And if they aren’t, then they are a waste of effort. But perhaps the biggest reason RCMs are doomed to failure is when they are completed too late. Why? Because if you need to do things like embed sensors to enable Condition Based Maintenance (CBM), then you need to think of this early. So what can you do? Embed your RCM in you Failure Modes and Effects Analysis (FMEA).
A FMEA is associated with ‘early’ design. And there are many similarities between an RCM and FMEA. In fact, the first 5 of the seven steps of a ‘traditional’ RCM are quite clearly a FMEA. And the last two steps are seen by many as also part of a FMEA, where the outcomes are better maintenance ideas. And … you don’t have to do the same thing twice if your RCM ‘sneaks’ into your FMEA.

Speaker: Greg Hutchins
Covid taught all of us the importance of managing suppliers, especially those from China and Asia. Risk became the top supply management concern over supplier delivery, quality, and cost. For example, just in time deliveries became just in case. Many common sense ideas of lean changed. Incoming, in process, and final inventories rose. Overall costs increased. Risk became the overarching concern for managing suppliers.
OEMs are now developing new operating models and sourcing models. ‘Make or buy’ decisions that were made 20 years or more ago are being reassessed. Sourcing decisions in China are being rethought. Domestic sourcing and reshoring are occurring rapidly
In this workshop, Greg Hutchins will discuss four ways to manage supplier risk, specifically: 1. Accept sourcing risks; 2. Diversify sourcing risks; 3. Share sourcing risks; and 4. Manage (control) sourcing risks.

Over the past few months, we’re received a few questions related to 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.
Send us your questions before the event, and we’ll have a prepared response. We’ll also have the chat and Q&A features turned on during the webinar (as always) so you can ask questions live. Plus, I’ll discuss the recent questions and how we answered them. This is an experiment on increasing engagement with our webinars and to prompt you and others to continue to send us your questions. If this goes well, we’ll be asking you for future Q&A focus areas.
Looking forward to seeing your questions related to ALT. It should be a fun conversation; see you there.
