But the one thing we do, which I think no one else does, is integrate hardware, software and services in such a way that most consumers begin to not differentiate anymore. They just care that the experience is fantastic.

Tim Cook, on collaboration at Apple.

Continuing:

And there can’t be politics. I despise politics. There is no room for it in a company. My life is going to be way too short to deal with that. No bureaucracy. We want this fast-moving, agile company where there are no politics, no agendas.

When you do that, things become pretty simple. You don’t have all of these distractions. You don’t have all of these things that companies generally worry about.

You don’t have silos built up where everybody is trying to optimize their silo and figuring out how to grab turf and all of these things. It makes all of our jobs easier so we’re freed up to focus on the things that truly matter.
