This is the complete text of Businessweek’s interview with Jonathan Ive and Craig Federighi, parts of which appeared last week. Every bit as revealing as the Cook interview. I get a real sense of the excitement these two have working with each other. Clearly, they love what they are doing. This from Ive:

I have always found—and I know the ID team has always found—that the discoveries you make when you are lucky enough to sit next to somebody who represents a completely different expertise, those discoveries can be really profound, and they’re really exciting.

Federighi on process:

We would prototype. We would review how it felt. Did it really work in the way we hoped it did once it was in our hands? We would get versions of it that we would live on, and then we would get together and we’d say, “I’m using it and I like this, but this bit is not coming together quite the way we wished,” and we’d iterate. So a lot of those conversations are just driven by perfecting the product together.

Ive on the emergence of parallax:

One of the things that we were interested in doing is, despite people talked about this being “flat,” is that it’s very, very deep. It’s constructed and architected visually and from an informational point of view as a very deep UI, but we didn’t want to rely on shadows or how big your highlights could get. Where do you go? I mean, there is only so long you can make your shadows.

It wasn’t an aesthetic idea to try to create layers. It was a way of trying to sort of deal with different levels of information that existed and to try to give you a sense of where you were.

There’s so much great stuff here. Interesting to hear their back and forth on complexity and collaboration, on working for Tim Cook, and the changes Tim Cook brought to Apple’s supply chain. Brilliant read.
