Potential is a one-sided evaluation. Momentum is an ongoing conversation. In a world of “potential,” it’s hard to imagine what, exactly, a career conversation looks like once Maureen has been shunted off into the lo-po dungeon. Momentum, on the other hand, represents the opposite of “up-or-out” thinking. And it’s the best concept to address one of the key survey items that measure engagement and performance: “In my work, I am always challenged to grow.” Potential doesn’t do that—it doesn’t challenge you to grow. It tells you that you either will, or you won’t.
