Simplicity design axiom: The complexity of the information appliance is that of the task, not the tool. The technology is invisible.
Donald A. NormanToo many companies believe that all they must do is provide a 'neat' technology or some 'cool' product or, sometimes, just good, solid engineering. Nope.

It requires designing the Total User Experience.
