• SAP software creates lots of incorrect orders – Whopping $15.5 millions in uncovered excess shipment – The system should cut down cost
• SAP software cannot handle vast number of daily orders – SAP R/3 software never used for a large amount of orders– Engineers never tested in advance – Project manager not familiar with software functions
• Software original design did not use manufactures wholesale system

on the train
• The system cannot make correct change
• Credit card system charges wrong amount
