This conflict-based approach works only if it is managed by a single decision-maker who owns the deadline and will break a tie. Often there is too much data, or the data is inconclusive. When that happens, people can debate for hours, a time sink that often ends in mediocre compromise and always incurs a hefty opportunity cost, since there are always better things for smart creatives to be doing than rehashing a decision for the umpteenth time. There is a point at which more analysis won't lead to a better decision. This is the most important duty of the decision-maker: Set a deadline, run the process, and then enforce the deadline. It's like the kids on the playground at recess; they will play forever, but when the bell rings they know they have to wrap it up and head back to class. (Hopefully employees are better behaved and less prone to hogging the monkey bars.) The decision-maker gets to decide how long recess lasts, then ring the bell.
