The title of the article I read is “What is Design Thinking anyway?” It explains that the Design Thinking concept had appeared and evolved during the last decade, and uses Tim Brown of IDEO definition: “[Design Thinking] a discipline that uses the designer’s sensibility and methods to match people’s needs with what is technologically feasible and what a viable business strategy can convert into customer value and market opportunity.”
Basically, Design Thinking applies the most basic designer’s tool to business: the abductive reasoning. Where the deductive logic reasons from the general to the specific and the inductive logic reasons from the specific to the general, abductive reasoning doesn’t look for data to find new ideas. It wonders first, challenges what’s existing or accepted explanations and creates. It is the logic of what might be.
However, the author warns us about this kind of reasoning. We must not use only abductive “logic”, risking to lose sight of what is possible and useful (in a business), but find a balance between all these forms of reasoning. Only then, a business might find the competitive edge.
If we take InnoCentive as an example, we can see how the creators of the website have thought "out of the box". Yes, they use the crowd sourcing system and it has been done before. But never at such a scale.
Whereas, crowd sourcing has been used in certain areas, for certain circumstances, InnoCentive uses it for a very large selection of themes. Any business can uses it and any "crowd" as well. They took an accepted practise and challenged it.
