A company I worked for 8 or 9 years ago did a system integration in the home office in Texas(I was in Virginia). It didn't work for about a month. Instead of retreating or maybe limiting it to that office until it could be fixed, they went nationwide. It never worked right. It was a retail company, and while the old system made the salesman figure the taxes correctly, the new one couldn't even come close. Customers refused to pay the bills until the amounts got fixed. The company almost went bankrupt. A friend still works there, and the new, new system does the same thing.
