Bob was a brilliant lawyer. He loved technology and was a wizard at math.
Back in the day when we used fax machines and they stood alone somewhere near the photocopier, Bob became enamoured with the idea of software that would allow the assistants to send faxes from their desktop. Bob ran various scenarios to demonstrate how much money we would save if we purchased this product. He calculated the salary and benefits earned by each assistant per minute and multiplied it by the number of minutes each assistant spent walking to and from the fax machine every day. We were going to save a fortune.
