An order of analytics, please

So, I finally got around to reading The New Yorker article about the man who was stuck in an elevator for 41 hours. Nicholas White, a production manager for Business Week, spent a weekend trapped in Car No. 30 of the McGraw-Hill building in New York City back in 1999. For 41 hours he paced the elevator, pried open the doors, repeatedly used the emergency phone, laid down to sleep and even smoked the rest of his cigarettes (aren't there smoke detectors in there!) ... but nothing. Nobody noticed him, not even the eight (yes, 8!) different guards who were on duty that weekend. Here's an easily overlooked parenthesized sentence in the 8,000 word article that caught my security-honed attention: (Eight McGraw-Hill security guards came and went while he was stranded there; nobody seems to have noticed him on the monitor.) Check out the video for yourself: I don't know how many screens these security guards monitored, but it was a weekend, people. There's little to no activity in the elevators for the duration of the video, and, there's even elevator maintenance work being done, which should at least garner some attention from the guards. (Of course, there's no maintenance work being done on the elevator car that actually malfunctioned and trapped White inside.) I'd say this is a great example of why security guards alone are not very effective. If it had been one guy who missed this, I'd say fine, maybe he was tired. But EIGHT! I know this was nearly 10 years ago and the analytic technology of today wasn't available, but if I were an analytic provider trying to convince companies to invest in notification-based video systems, this example would certainly be in my arsenal.
