There's a lot more to this, of course. Innovative organizations make work "fun," at least part of the time. People fearful of making any mistake, or having ideas shot down on take off, hold back. Good ideas have to be tried. They won't all work out, but people need the freedom to fail as long as it's not catastrophic. That's how we learn.
Of course, this seems to contradict discipline when processes absolutely, positively cannot be allowed to produce a defect or permit a mistake (air bag production or bank account balance information are examples). Most people's judgment reconciles this.
