Jeff Bezos stressed the importance of this model: Some decisions are consequential and irreversible or nearly irreversible--one-way doors--and these decisions must be made methodically, carefully, slowly, with great deliberation and consultation. If you walk through and don't like what you see on the other side, you can't get back to where you were before .... But most decisions aren't like that--they are changeable, reversible--they're two-way doors. If you've made a suboptimal [reversible] decision, you don't have to live with the consequences for that long. You can reopen the door and go back through .... As organizations get larger, there seems to be a tendency to use the heavy-weight [irreversible] decision-making process on most decisions, including many [reversible] decisions. The end result of this is slowness, unthoughtful risk aversion, failure to experiment sufficiently, and consequently diminished invention.
