Design is all but communication. Everything in this world talks to you – through its looks, through its behaviours, through its responses to the actions you apply to them. A product that conveys ambiguous, misleading, or plain wrong messages about its purpose or use confuses and pushes away. Conversely, a product that uses familiar signals to communicate its purpose creates a sense of familiarity and trust.

By and large, any product transfers knowledge of someone who knows a great deal about the problem to someone who knows little. Clear communication is essential to bridge that enormous gap.
