Practical Measurement Systems Analysis for Design – Work Smarter

podcast episode with speaker Rob Schubert

Gage R&R – this is mainly a quality tool, where 10% is a pass and 10-30% is “marginal.” What does that mean, or even better yet, how can I use gage R&R to provide meaningful results in a design environment where there are no specifications? In 30 minutes we will discuss how you can calculate Gage discrimination – the more useful result for a design situation, and even how to use it for destructive reliability tests.

Confidence in Reliability

podcast episode with speaker Chris Jackson

Reliability is a measure of your product or system. Confidence is a measure of you. But we often forget this. We often subject our new product, system or service to test after test until it reaches this thing called ‘required statistical confidence.’ But this is often an illusion. Which is great! Because if statistical confidence is often not ‘real’ confidence, then we don’t always have to resort to statistics to get confidence. In fact, those of us who exclusively rely on statistics are usually those who lack confidence in the product, system or service and need a security blanket to make them feel OK. This webinar talks about confidence from the perspective of the ‘process owner.’ The design team lead. The CTO. The junior engineer. And how you can get a much healthier version of confidence through the way we design and produce our ‘things’ so that when it comes time to test … we are (justifiably) supremely confident that we will absolutely dominate whatever statistical testing hurdle can be thrown our way. And this sometimes means we don’t need to deal with statistics at all!

Reliability and Maintenance

podcast episode with speaker Fred Schenkelberg

Both reliability and maintenance activities work to reduce failures and downtime. Perfect reliability of a system would eliminate the need for maintenance. Perfect maintenance would keep even poorly designed (reliability-wise) operating.

Together the work of reliability and maintenance professional can achieve more then each team working separately. Each brings a set of insights and skills to the conversation. Working together means improving the design of a system so it’s easier to maintain. It also means the day to day observations the maintenance teams make provides meaningful information to the reliability team.

Basic Mathematical Symbols and Stuff

podcast episode with speaker Chris Jackson

OK … we have all been there. We have all sat in some statistical presentation or read a document that contains mathematical symbols and statistical hieroglyphics that we don’t understand. And we pretend we do understand just so we don’t embarrass ourselves. And the people we don’t want to embarrass ourselves in front of are usually also pretending to understand those symbols and hieroglyphics as well. This webinar is a light (re)introduction into common mathematical symbols used in many engineering scenarios … including reliability. They can be really simple to understand, if you only know how. So if you see all manners of Greek letters or have to talk to someone who always uses the term ‘sigma’ … and you have no idea what they mean … then this webinar is for you.

Risk Decision Making, Frameworks, and Assessments

podcast episode with speaker Greg Hutchins

Disruption has been one of the major news items in 2022. Disruption results in risk. You can see ‘risk’ in almost every video, magazine, and blog. Russia invasion of the Ukraine. Supply chain disruption. Climate change. New business models. Reshoring. Inflation. Price of gasoline. Can you imagine $10/gallon gasoline.

Greg will answer the following:

What is risk based, problem solving and decision making in reliability engineering and quality?

What are risk PDCA, taxonomies, risk assessment, and risk management etc?

What are the two critical risk management frameworks for problem solving and decision making?

What are examples of risk assessment tools? [Read more…]

How to Take the Guess Work out of Expert Judgment

podcast episode with speaker Chris Jackson

Most humans can be quite technically minded. And sometimes we aren’t. Sometimes we expect every drug or medical procedure to be checked, approved, validated, tested on other people (et cetera) before we subject ourselves to whatever it is our doctor suggests. And other times we spend lots of money at casinos (note that I said ‘spend’ and not ‘invest’ or ‘win’). When it comes to reliability, we can sometimes be too technically minded. A reliability ‘number’ might not exist until our product has gone through exhaustive testing. Which can often be two years too late to do anything about if it turns out it doesn’t meet all our reliability dreams. So what can we do? Well … why spend money drying to generate information (through lengthy test) when you can just use the information stored in everyone’s brain? The most common answer (even if we don’t want to admit it) is that this sounds a lot like guess work. And guess work can sounds unprofessional. Or just wrong. But there are ways you can suck out information from a group of experts in a quantifiable and remarkably accurate way. Want to learn more? This webinar introduces you to some of the concepts that might interest you.

How to Check a Regression Fit

podcast episode with speaker Fred Schenkelberg

When fitting a line or curve to data, it’s a model. When modeling it worth remembering the George Box quote, “Essentially all models are wrong, but some are useful.” Yet, how do we separate a useful model from one that isn’t useful? One step in finding a useful regression model is to consider the residuals. BTW: Weibull analysis is another term for regression analysis. [Read more…]

What is Reliability Growth?

podcast episode with speaker Chris Jackson

Sounds simple right? And it is. Reliability growth literally refers to a process where we improve the reliability of a product, system or service. But sometimes we find ourselves in situations where it is expected that not only do we understand reliability growth … but measure it. And predict how much it will grow in the future. This is sometimes called Reliability Growth Testing (RGT) or Reliability Growth Planning (RGP) or Reliability Growth Prediction. And there are lots of equations and models for all these things. But do these models actually model the ‘real world?’ … can they work for you? … SHOULD they work for you? This webinar introduces you to the topic of reliability growth (both qualitative and quantitative) along with key concepts (like the Duane Failure Pattern) to help you work out if there is (or is not) a place for reliability growth in your organization.

Reliability and Safety

podcast episode with speaker Fred Schenkelberg

Is a reliable product safer? Are the safety elements of a product or system independent from its reliability performance? These and other questions speak to the complex relationship between reliability and safety.

What is Process Capability Analysis (PCA)?

podcast episode with speaker Chris Jackson

A ‘capable’ process is a really weak term for what we are dealing with here. In short, a process is considered ‘capable’ if it creates products that in spite of all the unavoidable natural variation in production still fall within the boundaries of what ‘good’ looks like. Perhaps instead of ‘capable’ we should say ‘amazing’! A ‘capable’ process will essentially create products that have a very, very small chance of being defective. So how do we get here? SPC can help. But how do we measure how ‘capable’ our process is? And can we use this measurement to (for example) work out how many Parts Per Million (PPM) defects you are likely to get? This webinar introduces you to the concept of process capability including well known indices like CPK along with what this means for your process. [Read more…]

Reliability and Quality

podcast episode with speaker Fred Schenkelberg

Some of my best friends are quality people. This is despite the notion that reliability is just one of many factors of quality, while I suggest reliability is all of quality and over time. There are a lot of similarities and common objectives with quality and reliability efforts. Plus, a few differences.

What is Statistical Process Control or SPC?

podcast episode with speaker Chris Jackson

You may have heard of Statistical Process Control (SPC), 6-sigma, Shewhart, the Japanese Economic Miracle, X̅ – R Charts … or perhaps none of them. So if you have heard of these things (and are confused by them) or if you are involved in ‘processes’ (especially manufacturing) then this webinar might help you out. [Read more…]

Why We Use Statistics

podcast episode with speaker Fred Schenkelberg

You may fondly, or most likely not fondly, your undergraduate course on probability and statistics. The calculations of various winning hands with card games was interesting and connected to the early ‘invention’ of probability and statistical methods, yet the jar with colored beads was rather boring.
