Reliability and Volume
Abstract
Dianna and Fred discuss reliability and volume, comparing high-volume products with low-volume high-stakes products.
Key Points
Join Dianna and Fred as they compare reliability strategies for NASA’s one-of-a-kind lunar instruments versus mass-produced consumer electronics.
Topics include:
- why the definition of reliability remains constant for the customer
- how risks shift from craftsmanship and environmental uncertainty in low-volume projects to manufacturing variability in high-volume production
- which standard reliability tools work for every project, and which tools lose their edge when you only have a sample size of one
Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.

In Reliability and Volume, Fred and Dianna explore the distinct challenges engineers face when working on opposite ends of the production spectrum.
Dianna describes her recent tour of a NASA facility where only a single lunar environment monitoring station is being prepared for launch. This extreme low-volume project requires deep technical craftsmanship and a focus on surviving specific environmental stresses like solar radiation and lunar dust.
While the stakes are high for a single unit, the fundamental goal of ensuring the product works for the end user remains identical to high-volume manufacturing.
In contrast, high-volume production introduces the threat of manufacturing and vendor variability. When millions of units are distributed, even a small percentage of defects can devastate a company’s reputation and financial bottom line.
Fred and Dianna discuss how tools like FMEA and accelerated life testing apply across both domains, though methods like process control charts are specialized for mass production.
Ultimately, engineers use reliability to reduce uncertainty and apply it to help teams make informed decisions, no matter how many units are being shipped.
