Yes, that is exactly what Apple did with the iPhone. They wrote the interface then tested it over and over again and made optimisations on every iteration.. This was before it was released to the general public.

The article is talking about optimising before you can prove where the problems are... Apple had excellent testing which showed where a lot of issues were. Some issues may well have not been discovered until a wider audience had access though.

Testing can happen before you release a product you know? You new fangled startup MVP types only think good testing happens on paying customers. Fuck you guys.
