A new product comes into the warehouse. Which pick face do you give it? Let me guess, one which is empty! Is it the most suitable for the number of times you are going to access it or replenish it? You have no idea as you don’t have any history.
A period has passed and you now have some history as to how it is moving. However, can you see it in comparison with all the other products you are picking? Is it an “A” mover or a “B” or a “C”?
