San set out to improve efficiency at the shirt factory but, as we find out later in this unit, his plans turned out not quite as he had expected.

Sam Adams, Industrial Engineer

If you ask my mother how I happened to碰巧become an industrial engineer, she'll tell you that I have always been one.

She means that I have always wanted everything to be well organized and neat. When I was still in elementary school, I liked to keep my socks in the upper left-hand drawer of my bureau, my underwear in the upper right drawer, shirts in the middle drawer, and pants, neatly folded, in the bottom drawer.

In fact, I was the efficiency expert for the whole family. I used to organize my father's tools, my mother's kitchen utensils, my sister's boyfriends.
