As soon as he walked into Deming's office, it was obvious that something was amiss. Steve was sitting at his desk, hunched forward, his hands supporting his head, staring into a large box which was surrounded by dozens of empty glasses. Uncertain as to whether he should disturb his reverie, John stopped and stood silently in front of the desk. As he debated whether to say something or to just quietly slip out the door, Steve spit into the box and began chuckling to himself. Red marbles, John.
Red marbles are the problem.
John watched in silence as Steve filled all the other glasses with marbles. There's more white marbles than red ones. We like that. But there's still too many red marbles. Now watch this.
