Innovation.
-One school says necessity is the mother of invention, so great progress comes from adversity and pressure. Look at how war progresses technology.
-The other school says that real innovation comes from having space - no pressure, freedom to let your mind wander, in other words Slack.

Which is right? I think they're not actually the same sorts of invention. One is creative problem-solving within given constraints (ie. best with what we have), the other seems more apt for step change (i.e. best thing possible). It may also be that the wartime thing's a red-herring, because war also leads to massive investment, management decisiveness and a clearer set of priorities. at Henley KM Forum yesterday it was also suggested that managers should focus on creating space and let the pressure come from inside the innovators. I suspect managers need to be more nuanced than that depending on the personalities of their people.
