Talking with Don Norman felt a little like tracing the roots of this whole season. I first came to his work through The Design of Everyday Things, and one reason I wanted him on the podcast was that so much of what he wrote about physical products maps directly to software. This conversation made that connection even clearer for me.
What stood out most is how often "user error" is really design error in disguise. Don told stories about everything from Three Mile Island to Unix text editors, and the pattern was the same: people were often doing the best they could inside systems that had already set them up to fail. That is such an important framing for product engineering because it shifts the question from "why did the user mess this up?" to "why did the product make this so easy to get wrong?"
Watch What People Actually Do
One of the strongest through-lines in the episode was observation. Don kept coming back to the idea that when lots of people are using a product in ways you did not expect, that is not just noise. It is a signal. Sometimes it means they found a new use case. Sometimes it means the product is forcing a workaround. Either way, if you want better products, you have to watch what people actually do instead of only defending what you intended.
I appreciated that because it connects product engineering to humility. You do not get the best insight by arguing users into your mental model. You get it by paying attention to the gap between the model in your head and the behavior in front of you.
The Scope Is Bigger Than Usability
Another thing I appreciated is that Don did not stop at usability. He talked about how design now affects not only individual interactions, but also the environment, culture, incentives, and the quality of life people experience at scale. That is a bigger frame than "make the interface clearer," but it feels like the right one.
By the end of the conversation, the question was no longer just how to make a product easier to use. It was how to make technology serve humanity better. That is what led Don to focus on Design for a Better World and the Don Norman Design Award, and I thought that gave the episode a meaningful ending: product engineering is not only about reducing friction. It is also about taking responsibility for consequences.
What I Am Carrying Forward
If I were reducing this episode to one practice, it would be this: spend more time observing real work before you decide what needs fixing. Watch the hesitation, the workarounds, the repeated confusion, and the places where people have quietly adapted to a bad system. Those are often the clearest clues about what the product really needs.
