A nice quote I heard from one of the other speakers last week was this:
Reward success, celebrate failure, and punish inaction
Successful innovation, whether it is designing a compelling new product, or completing a technical challenge that gets your product released on time requires failure. Too many organizations create a culture where failure is severely punished, such that a fear of failure leads to inaction rather than a bias towards success.
With ethical and moral failings that damage lives being the rare exception, failure is one more step on the road to success, and truly a necessary ingredient for innovation.
