Num artigo extremamente importante para os interessados em Design Thinking, de Don Norman.
[Designers have developed a number of techniques to avoid being captured by too facile a solution. They take the original problem as a suggestion, not as a final statement, then think broadly about what the real issues underlying this problem statement might really be (for example by using the "Five Whys" approach to get at root causes). Most important of all, is that the process is iterative and expansive. Designers resist the temptation to jump immediately to a solution to the stated problem. Instead, they first spend time determining what the basic, fundamental (root) issue is that needs to be addressed. They don't try to search for a solution until they have determined the real problem, and even then, instead of solving that problem, they stop to consider a wide range of potential solutions. Only then will they finally converge upon their proposal. This process is called "Design Thinking."
Although I still stick to my major point that design thinking is not an exclusive property of designers—all great innovators have practiced it—I now do believe that designers have a special claim to it.
...what we call design thinking is practiced in some form or other by all great thinkers, whether in literature or art, music or science, engineering or business. But the difference is that in design, there is an attempt to teach it as a systematic, practice-defining method of creative innovation. It is intended to be the normal way of proceeding, not the exception.
We need to question the obvious, to reformulate our beliefs, and to redefine existing solutions, approaches, and beliefs. That is design thinking.
