According to the WSJ, Starbucks "vice president of lean" (and apparently mean), has discovered performance analysis.
Heeellooooo! That would be The Principles of Scientific Management, developed by Frederick Winslow Taylor almost a century ago. Of course, it's uncool to be a prophet in your own land, so more notice was eventually taken in Japan then the USA, after WW-II. Baristas will probably be less than bullish on it, but they can take heart that this genius idea by the VP of Lean is totally pre-Toyota.
