What is the Lognormal Distribution and How does it Help Me
What is the Lognormal Distribution and How does it Help Me
podcast episode with speaker Chris Jackson
Some of you might have heard of the ‘bell curve.’ Some of you might have heard that the ‘bell curve’ is sometimes called the ‘normal distribution.’ There is a reason it is called normal … but that is not always obvious. But then there is the ‘lognormal distribution.’ What is this? … and how does it relate back to the ‘bell curve?’ There is a really good reason for this link. And the good thing is that all you need is just a little bit of knowledge about how something breaks (and is repaired) to help use the lognormal distribution to help you make lots of important decisions … easily!

Warranty Analysis for Repairable Systems
Abstract
Chris and Fred discuss how we do warranty analysis … which usually means trying to understand how many things fail during a warranty period (before you need to start paying for it …) Where do you start?

Getting Started with Vibration Testing
Abstract
Chris and Fred discuss how we get started with vibration testing. We are often told (or feel like) we need to conduct vibration testing on new products and components. But what does that mean? Where do we start?

Why don’t LED Lightbulbs last as long as they say they will?
Because the people that make them lie.
Not ‘obvious’ lying where lightbulb manufacturers calculate one reliability number and deliberately choose to put another number on their lightbulb packaging. But ‘insidious’ lying where they deliberately choose to measure the wrong thing to get a better number.

The Trouble with Habits
Abstract
Chris and Fred discuss the issues we often have with ‘habits.’ Habits can be good for us. But ‘bad habits’ are just that. Ever heard the excuse ‘but that’s the way we have always done it?’

What’s Wrong with Using FITs?
What’s Wrong with Using ‘FITs’ to Measure Electronic Component Reliability?
podcast episode with speaker Chris Jackson
Every industry has its own way of characterizing reliability metrics. For example, the ball bearing industry uses the metric ‘B_10’ to represent the time by which they expect 10 % of all ball bearings of a specific type to fail. Electronic component manufacturers use the term ‘Failures in Time’ of ‘FITs’ to describe the reliability of their products. But what is a FIT? And how can you use it to measure reliability? Did you know that many electronic manufacturers advertise ‘FIT values’ that imply a mean time to failure of over 1 000 years?

What’s the Difference Between FMEA and FMECA?
What’s the Difference Between FMEA and FMECA?
podcast episode with speaker Chris Jackson
And the answer is not ‘the letter C.’ A FMEA is a group activity that follows a logical (and time-proven) structure to effectively ‘brainstorm’ what are called ‘corrective actions’ for existing or likely problems in design and manufacture of products. Production teams that comprise designers, engineers, technicians and manufacturers typically have a wealth of existing knowledge and understanding of the product being developed. But some people will tell you that an FMECA is not an FMEA. And many government agencies, in particular, demand FMECAs over FMEAs. Interested to understand the difference (if any) between FMEAs and FMECAs? … and How can you make an FMECA work for you? Join us at this webinar!
