Don’t Ignore your Water Spider a great post by Mike Wroblewski:
The second night was little better and I quickly evaluated the improvements from the night before. Later that second night, I made more improvements. Each day, I continued the cycle of experimenting with the improvements and making adjustments to see what worked best. By the end of the week, my pedometer reading hit only 10,000 steps or five miles and not one line operator had to get their own parts or screamed for me the entire shift.
