I just had to share this written by Tim Brown, CEO and president of IDEO. It's the breakdown of the mindset of a design thinker. Published by Harvard Business Review.

Contrary to popular opinion, you don’t need weird shoes or a black turtleneck to be a design thinker. Nor are design thinkers necessarily created only by design schools, even though most professionals have had some kind of design training. My experience is that many people outside professional design have a natural aptitude for design thinking, which the right development and experiences can unlock. Here, as a starting point, are some of the characteristics to look for in design thinkers:

Empathy.

They can imagine the world from multiple perspectives—those of colleagues, clients, end users, and customers (current and prospective). By taking a “people first” approach, design thinkers can imagine solutions that are inherently desirable and meet explicit or latent needs. Great design thinkers observe the world in minute detail. They notice things that others do not and use their insights to inspire innovation.

Integrative Thinking.

They not only rely on analytical processes (those that produce either/or choices) but also exhibit the ability to see all of the salient—and sometimes contradictory—aspects of a confounding problem and create novel solutions that go beyond and dramatically improve on existing alternatives. (See Roger Martin’s The Opposable Mind: How Successful Leaders Win Through Integrative Thinking.)

Optimism.

They assume that no matter how challenging the constraints of a given problem, at least one potential solution is better than the existing alternatives.

Experimentalism.

Significant innovations don’t come from incremental tweaks. Design thinkers pose questions and explore constraints in creative ways that proceed in entirely new directions.

Collaboration.

The increasing complexity of products, services, and experiences has replaced the myth of the lone creative genius with the reality of the enthusiastic interdisciplinary collaborator. The best design thinkers don’t simply work alongside other disciplines; many of them have significant experience in more than one. At IDEO we employ people who are engineers and marketers, anthropologists and industrial designers, architects and psychologists.
