Design thinking is not an exclusive property of designers – all great innovators in literature, art, music, science, engineering, and business have practiced it. What's special about Design Thinking is that designers' work processes can help us systematically extract, teach, learn and apply these human-centered techniques to solve problems in a create and innovative way – in our design, in our businesses, in our countries, in our lives.
