Something bigger is going on, more powerful than the adoption of a single school of thought. The secret isn't design thinking, it's "hybrid thinking": the conscious blending of different fields of thought to discover and develop opportunities that were previously unseen by the status quo.
Hybridity matters now because the problems companies need to solve are simply too complex for any one skillset to tackle.
Hybrid thinking is much more than gathering together a multidisciplinary team. Hybrid thinking is about multidisciplinary people. ... Hybrid thinkers [are] folks who can connect the dots between what's culturally desirable, technically feasible, and viable from a business point of view.
I think the key here is to recognize that hybrid thinking doesn't have to be any particular combination of thinkings, but represents an open-minded quest to bring many thinkings together.
Any new or new-to-us thinking (for example, design thinking is attracting a lot of interest in some circles) should generate some new sources of innovation and value. This is because new thinking is always implicitly combined with old thinking, and so we have hybrid thinking by default. The problem arises when the new thinking is given the full credit for any successful outcomes, because it then starts to become dominant and the hybridity (which was perhaps the true cause of the success) is weakened or altogether lost.
