Amazon has a leadership principle (http://www.amazon.jobs/principles) that seems to be related:

"Bias for Action

Speed matters in business. Many decisions and actions are reversible and do not need extensive study. We value calculated risk taking."

Interesting correlation with Kent Beck's note that "Not all decisions are reversible ... the two kinds of decisions need to follow completely different workflows."

Anecdotally, I've observed that the leaders that can distinguish between these two types of decisions and learn not to sweat the small stuff increase their teams' velocities by increasing the confidence that you can do the right thing now and handle the outcome when it comes.
