Ideas come from people, obviously.
It's not an easy question. Many of the essentials of a fertile, creative environment are anathema to an orderly, well-run organization. Setting short-term goals, then quickly testing to see if they will bear fruit is similarly absurd. Ideas may come like thunderbolts, but it can take a long time to see them clearly - too long. And ideas are often born unexpectedly - from complexity, contradiction, and, more than anything else, perspective.
