Scientists are always skeptics.

I think a successful company is one where everybody owns the same mission. Out of necessity, we divide ourselves up into discipline groups. But the goal when you are actually doing the work is to somehow forget what discipline group you are in and come together. So in that sense, nobody should own user experience; everybody should own it.

If you think of the product as a service, then the separate parts make no sense - the point of a product is to offer great experiences to its owner, which means that it offers a service. And that experience, that service, comprises the totality of its parts: The whole is indeed made up of all of the parts. The real value of a product consists of far more than the product's components.

Our information lives will be better served when we are free to get to our information from wherever we are, with any device available.

What makes something simple or complex? It's not the number of dials or controls or how many features it has: It is whether the person using the device has a good conceptual model of how it operates.

We delude ourselves if we believe that skilled behavior is easy, that it can come about without effort. We forget the years of tuning, of learning and practice it takes to be skilled at even the most fundamental of human activities: eating, walking, talking, reading, and writing. It is tempting to want instant gratification - immediate expert performance and experiential pleasure - but the truth is that this primarily occurs only after considerable amounts of accretion and tuning.

If people keep buying poorly designed products, manufacturers and designers will think they are doing the right thing and continue as usual.
