marketing or R&D? It's a trick question, of course. But it's a useful question for Fortune 100 companies to consider. Has your company made a conscious choice of how it "allocates" this leadership role?
Allocating innovation to one group over the other will yield a different business result. The approaches to innovation by marketing are dramatically different than approaches to innovation by R&D, so the outputs will be dramatically different. The question becomes: which group will outperform the other? Technical-driven innovation or marketing-driven innovation?
