My wife and I spent the weekend with another couple who's son is currently studying for his PhD in physics. He works for Dale Folwell as a consultant part time. Dale tasked him with designing a system to determine how best to finance state assets, everything from cars, trucks, computers, printers, office furniture, etc. For example, does it make sense to lease equipment, sell it, replace it, and at what intervals, in order to reduce overall ownership costs. All this stuff was on a 300,000 line spreadsheet- too much for Excel, so he requested a database program. (He has the program on his personal computer but the state does not allow its use in their offices, nor removal of any data from state offices.)
Going through the required requisition channels, delivery of the software took 8 weeks. During that time, he planned out all the regression analyses and had all the input ready to go. Thirty minutes after installing the new software, he had the final product for Folwell's use. I forget the exact annual dollar amount of projected savings, but it was in the hundred million dollar range.
