Give employees the 'Mr. Potato Head test'?

Does Mr. Potato Head have a place in employee training or new hire orientation? This employer thinks so.
Starbucks is rolling out a company-wide efficiency initiative, with the goal of getting employees to work faster. Part of the training process: taking apart and reassembling a Mr. Potato Head doll. For two hours straight.
One Starbucks manager told the Wall Street Journal that a member of the “lean team” came to her store, sprinkled parts of the toy across several tables and timed the manager with a stopwatch as she assembled the pieces.
Then she was told to do it again. And again. And again, for nearly two hours.
How’d that make the manager feel? Impressed, actually.
Though the first time trial took more than a minute, by the end, she could complete the task in 16 seconds. “That really opened my eyes,” the manager said.
