Enable and empower teams to make fast and courageous decisions. - Eric Ries

The sandbox also promotes rapid iteration. When people have a chance to see a project through from end to end and the work is done in small batches and delivers a clear verdict quickly, they benefit from the power of feedback. Each time they fail to move the numbers, they have a real opportunity to act on their findings immediately. Thus, these teams tend to converge on optimal solutions rapidly even if they start out with really bad ideas.

A few years ago, a team that sells products to large media companies invited me to help them as a consultant because they were concerned that their engineers were not working hard enough. However, the fault was not in the engineers; it was in the process the whole company was using to make decisions. They had customers but did not know them very well. They were deluged with feature requests from customers, the internal sales team, and the business leadership. Every new insight became an emergency that had to be addressed immediately. As a result, long-term projects were hampered by constant interruptions. Even worse, the team had no clear sense of whether any of the changes they were making mattered to customers. Despite the constant tuning and tweaking, the business results were consistently mediocre.

When blame inevitably arises, the most senior people in the room should repeat this mantra: if a mistake happens, shame on us for making it so easy to make that mistake.
