What is Reliability Growth?
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.

Hierarchy of Engineering
Abstract
Chris and Fred discuss the ‘hierarchy’ of reliability engineering. Which is the hierarchy of the knowledge and terms we need to follow when we learn about reliability engineering. Is it possible to organize our thoughts in a better way?

SOR 738 Design Use of Cpk
Design Use of Cpk
Abstract
Chris and Fred discuss the use of this thing called ‘Cpk’ which is what we call a ‘capability index.’ This is a measure of how ‘capable’ a typically manufacturing process is, which helps us understand the percentage of defects we create. But reliability engineers often see this as something that ‘manufacturing teams’ or ‘quality people’ do. But is it?

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…]
SOR 732 Reliability Goals and Allocation
Reliability Goals and Allocation
Abstract
Chris and Fred discuss reliability goals … and how we ‘allocate’ them to components and subsystems. This is really important, as subsystems and components are often built and designed by different designers or organizations. So how do we translate system-level goals to MEANINGFUL lower-level goals?

Easy to Ask Hard to Answer
Abstract
Chris and Fred discuss questions that are easy to ask … but hard to answer. And these questions are often hard to answer because the person asking the question hasn’t thought about the REAL question they are trying to answer. So how many samples do I need for everything to be OK???

SOR 726 Statistics, Mechanisms, Facilitation
Statistics, Mechanisms, Facilitation
Abstract
Chris and Fred discuss how statistics, mechanisms, and other technical words that come from ‘reliability engineering’ in contrast to softer terms like ‘facilitation.’ This comes from discussions Chris has had during his Statistical Process Control (SPC) course that he has run previously. So what is the big deal about these words? Well … you can know everything there is to know about statistics and failure mechanisms – but if you can’t make things better then it is all for nothing!

Common Slope Assumption
Abstract
Chris and Fred discuss a ‘common slope assumption’ … which is something that only those of you with reliability engineering experience will have heard about. This is all about what we called ‘accelerated life testing’ where we increase stresses to accelerate failure. And software that is used to model accelerated life testing. Keen to learn more?
