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.

When you have trouble with things—whether it's figuring out whether to push or pull a door or the arbitrary vagaries of the modern computer and electronics industries—it's not your fault. Don't blame yourself: blame the designer.

AS for all those mistakes I make - they are on purpose - to teach you how to deal with them

It is relatively easy to design for the perfect cases, when everything goes right, or when all the information required is available in proper format

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

Products were once designed for the functions they performed. But when all companies can make products that perform their functions equally well, the distinctive advantage goes to those who provide pleasure and enjoyment while maintaining the power. If functions are equated with cognition, pleasure is equated with emotion; today we want products that appeal to both cognition and emotion.

In my opinion, no single design is apt to be optimal for everyone.
