Jeff Hay, PhD is the founder and CEO of RDI Technologies. He is the inventor and visionary behind Motion Amplification® and the Iris M™, which allows you to amplify and measure motion with the use of video. His products are moving industrial vibration to the visual spectrum. His passion is using his background in applied optical technology to change the way you see and measure motion in industrial applications.
In this episode we review sampling for design tests. We talk through a generic thought process for choosing a statistically relevant sample size and propose some basics that we can all learn about to better understand sampling.
Our goal is for us to be able to better talk through a sampling scenario with our quality and reliability engineering friends, and to better prepare for the information that they’re going to want to know when asked, “How many do we need to test?”
Michelle Ledet Henley is President of TMG Frontline Solutions where she has spent the past 25 years helping hundreds of organizations navigate the difficult waters of organizational change using a game-based simulation. Her enthusiastic facilitation style along with the innovative workshop design bring the workforce (even the most skeptical among them) energetically onboard with their site’s reliability improvement efforts. Co-authoring various articles and the book Level 5 – Leadership at Work, the sequel to the popular Don’t Just Fix It, Improve It, Michelle has become a thought leader on the emerging and often misunderstood topic of defect elimination.
Carl and Fred discussing the underlying mechanisms of failure, and how they impact our analysis and understanding of reliability.

It costs our customers to own our designed products. It costs them initially to purchase it, but it also costs them to use it, maintain it, repair it, and eventually dispose of it. And it costs our company in ways too, like processing, training requirements for customers, and warranty repair costs.
Life cycle costing can help our team choose between design alternatives, like alternate design options, features, manufacturing methods, or suppliers.
Carl and Fred take on the subject of Risk Priority Number, also called RPN, when used in FMEA. Is RPN a good way to prioritize risk in an FMEA, or is there a better way?

Good reliability requirements are going to drive our design decisions relating to the concept, the components, the materials, and other stuff. So, the moment to start defining reliability requirements is early in the design process. But, what makes a well-defined reliability requirement? There are five aspects it should cover: do you know what they are?
We’ll describe what makes a good reliability requirement and examples of common (but not good) requirements.
Kirk and Fred discussing a very important question in all of unreliability.

We have good requirements for the reliability of our design. We also have a preliminary design with ideas of how we’re going to manufacture it. Is our design idea good enough? Are there things we should do to improve its performance and reliability?
For a physical product, there are three general stages in its life cycle. In many cases the failure rates of physical products can be represented by a reliability bathtub curve. This curve is really a plot of a hazard rate function, also known as a failure rate function. We talk about data collection in the early design phase, what types of failures are typical for each phase, and design decisions we may make to improve our reliability, based on the failure rate function we plot for our system.
Chris and Fred discuss a real-world problem … how do we use reliability engineering tools to work out how select a hospital power supply system.
