If you don’t reward good ideas (they don’t even need to be particularly good or novel, just common sense), you’ll have a company trying to grow something that’s reached its peak usage with motivational speeches, very inspiring leaders and good old pressure on employees as a form of local optimization.
I just don't think most companies run this way, maybe it's the military way of thinking of strict hierarchy rather than a market where the best ideas can develop or where you can at least break out of the hierarchy to get something started.
The MBAs and bean counters would probably argue that it's important to get certain unpopular things done, but I think a market would solve that too, as soon as something becomes a bottle neck, someone would step in.
My impression is that organizations are far too centered around VPs and directors who get to carry on without having to prove themselves again in the new situations they're in.
They care about the quarterly report and right now the best way to improve short-term performance is to milk your existing locked-in customers for as much money as possible.
