Perhaps relevant...Ed Catmull (Pixar) on collective creativity:
A few years ago, I had lunch with the head of a major motion picture studio, who declared that his central problem was not finding good people—it was finding good ideas. Since then, when giving talks, I’ve asked audiences whether they agree with him. Almost always there’s a 50/50 split, which has astounded me because I couldn’t disagree more with the studio executive. His belief is rooted in a misguided view of creativity that exaggerates the importance of the initial idea in creating an original product. And it reflects a profound misunderstanding of how to manage the large risks inherent in producing breakthroughs.
