Where is the Big Money in Maintenance?

摘要

I had a chance to bid the mainte-nance contract on a police services center about 15 years ago. I was somewhat intrigued about the invitation for two reasons: 1. I wasn't the installing contractor, so why wasn't the installing contractor taking care of that? 2. The systems were brand new, installed within the last six months, so why did they even think they needed a maintenance contract so early in the game?
