You won't catch me giving clear lectures.

Any time you see signs or labels added to a device, it is an indication of bad design: a simple lock should not require instructions.

How do you discover a need that nobody yet knows about? This is where the product breakthroughs come through.

Forget the complaints against complexity; instead, complain about confusion.

The design of everyday things is in great danger of becoming the design of superfluous, overloaded, unnecessary things.

When a device as simple as a door has to come with an instruction manual—even a one-word manual—then it is a failure, poorly designed.

No product is an island. A product is more than the product. It is a cohesive, integrated set of experiences. Think through all of the stages of a product or service - from initial intentions through final reflections, from first usage to help, service, and maintenance. Make them all work together seamlessly. That's systems thinking.
