If you don't have a standard work, you can't improve standard work. Ever been to a bar or restaurant where a bartender or waiter/waitress was on their first day. They follow someone around and get this hint and that hint and then get thrown into the deep end of the pool. Then they get nagged about doing this wrong and that wrong dozens of times. Nagging at someone about doing things wrong, is not the same as teaching them to do thing right. Standard work solves this.
