How Many Do We Need To Test?

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…

The Way We Test Matters

We can look at test methods like a product in and of itself. Because tests also have requirements and need to produce usable results, we validate against those requirements. Validating our test method also ensures that they are precise and accurate. We talk about things to consider when looking at product tests: tying test methods to the…

What is ‘Production Equivalent’ and Why Does it Matter?

We’re in the middle of our design process and we’re getting some of the first parts in hand, from prototyping or benchtops or our manufacturing cell. Let’s test them and finish our verification testing! Maybe we shouldn’t. We talk about the concept of production equivalent: what it means and when it’s important to consider. Transcript Expand…
