There still needs to be a balance between the innovators and the engineers, though.

First, because innovators, even when the ideas are very good and sound, are not so hot at follow through.

Second, because sometimes ideas that seem wonderful are just not practical to implement.

Finally, though, nothing smashes innovation as quickly as a change-resistant environment. Nothing.

I have resolved myself that change at my school will be VERY slow until the two staff members with the longest time in retire. They passively-aggresively resist all change. It's frustrating.
