Combinatory play seems to be the essential feature in productive thought ~ Albert Einstein
No combination has such volatile innovative potential as that which ignites when expertise from disparate disciplines collides.
As an example, what do cartography and mammography have to do with one another? The former influenced improvements in the latter.
How did this happen? As reported on the website MedGadget, it turns out that to a NASA scientist the lakes of northern Wisconsin look very much like dense breast tissue. You can see the similarity for yourself by following the link.
Have you participated in projects that were so tightly controlled that unexpected collateral innovations were overlooked? Do your project teams practice the inclusion of diverse expertise to catalyze innovation?
