The dark side of collaborative cultures is the allergy they foster to holding anyone responsible for having the ball. “Mine oryours?” is unfortunately not in the common vocabulary of many such organizations. There is a sense that that would be impolite. “We’re all in this together” is a worthy sentiment, but seldom a reality in the hard-nosed, day-to-day world of work. Too many meetings end with a vague feeling among the players that something ought to happen, and hope that it’s not their personal job to make it so.
