I can relate. In a previous life the internal support group was planning a rollout of a major XP update to around 200,000 machines. Some home-grown stuff had very stringent dependancies and they were briefing the CIO on the multi-month test plan. His observation was something like "I don't see why you can't just roll it all out tonight, after all, it's still Windows".
Thankfully, he wasn't CIO very long.
“His observation was something like “I don’t see why you can’t just roll it all out tonight, after all, it’s still Windows”.
CIOs like this make Dilbert’s boss look like the very quintessence of reasonableness.
