This kind of system is notoriously difficult to switch to. In theory a centralized system with a good algorithm should easily do better than the local employee who only has local information, however before you switch the system on, you only have the data which has been collected before and this is probably incomplete and inaccurate data, so the algorithm will miss some peaks and suffer out of stock issues, which will generate more garbage data as you cannot measure demand of an out of stock item.
