The Design Dilemma: Dismay vs. Delight - Don Norman

What causes this mix of dismay and delight? Designers are trained as craftspeople, without any substantive knowledge of the content areas in which they do their work. My dismay comes from their lack of understanding and by the confidence with which they proclaim masterful solutions to the world’s problems. They often produce innovative, clever solutions, but with no evidence that they have actually addressed the most critical parts of the problem or that their solutions actually work. They are often unaware that others have toiled with those issues for decades, that the problems are deep and profound, and that no single approach, no matter how brilliant, will suddenly solve all the issues.
