> If you work in IT, and you learn only from your own cockups, you need to read more. I can remember even back in the days of PC Pro, reading columns about the "sledgehammer" test - consultants hired to ensure the system is resilient, so laying a sledgehammer on the meeting room and saying to the IT guy "Quite how sure are you?" Even getting verbal permission from the CEO to trash one server and chalk it up to expenses only to see the IT guy gulp...
I remember that one. The consultant (singular) was Jon Honeyball, and the tool was his well-used industrial-weight chainsaw, not a sledgehammer. It was a board-room power-battle, not (really) a technical issue.
Honeyball was consulting *for*the*CEO*, who didn't think the CIO was as sure of the redundant servers as he claimed. And he was right. Honeyball suggested the chainsaw test, and the CIO raised a reasonable objection related to the cost of the server that would be destroyed. The CEO said that it wasn't a problem, and that he would sign an authorisation to replace it, seeing as how he had asked for it to be destroyed. The CIO then bottled out and had to admit that he wasn't as sure of the redundant architecture as he had claimed.
