Predicting the future is a difficult job. For demand planners who don't own a working crystal ball, it's only getting harder.

Data volumes are exploding, and legacy technologies are more of a hindrance than a help. All of this means that demand planners are consistently forced to choose between accuracy and speed - you can never have both, and often you get neither.
