Ask HN: What are some problems solved in unrelated domains?

#1
Elaborating, what are some problems that were being experienced by one industry or domain but were solved elsewhere and were adopted by the industry plagued by the problem? Even better if the answer was really obvious for the people who solved it or solving it involved cross-domain knowledge.

For context, I recently heard having a breadth of knowledge (along with depth in chosen areas) is really helpful in problem solving and I'm looking for concrete examples for the same.

A real popular one would be QR codes. They were initially created to track manufacturing processes in the automotive industry. And you know how it is these days...

I feel like QR codes failed as a general UI tool. I get annoyed whenever I have to deal with one. They wee HUGE about 10 years ago. Now, not so much.

I don’t know about other places, but they’re getting a lot of use in NYC right now as a method for viewing restaurant menus for outdoor dining.

Same in Germany. Also for payment with WeChat in China.

Kanban comes from the automotive industry, and works really well in the tech industry. The Toyota Production System is a brilliant set of principles and practices that fit well in most industries. Toyota sent engineers to optimize street kitchens some years ago.

ISO 9001 was implemented in manufacturing, and is quite popular in many circles of hell.

Maybe control version? From software to a lot of other information industries.

Also, not an industry, but I think that some mathematicians use category theory to translate insights from one domain to other.

(Trying the recipe itself here to find a meta-recipe) I think an insight itself from category theory to a more general recipe could be: don't try to move "laterally" to other industry, but go first "up" from a specific solution to a more general interpretation, and see what more you can solve "down" from there.

I wonder about that stuff too and sometimes I think some problems are really like:

I suspect a big one is "regular" engineering vs software engineering. Regular engineering has schedules and (apart from the apple campus) can put up a building in a predictable amount of time. Also testing and maintenance and more.

It is big for payments in India too.
