So, we were the first group of people doing 6 Sigma at GE. To get some "data" for us to use for doing statistical calculations, 30 people were sent to 2 different McDonalds with stop watches, and $5 to order lunch. Half were sent through the drive through and the other half, the counter inside for take out.
Drive through was faster at lunch time. Mid afternoon, counter take out was faster.
Funny, not long after, McDonalds installed a timer system at the drive through. This was 1996.
