A CMDB is like a Swiss bank account
I have an analogy for CMDB - it is like a Swiss bank account. Allow me to paraphrase some of the conversations I've had around CMDB:
Him (it's always a "him"): Everybody needs a Swiss bank account.
Me: No they don't.
Him: Of course they do. It is the only sensible effective place to keep your spare liquid cash.
Me: Since 2009 I don't have any spare cash.
Him: it doesn't need to be large amounts. Anything over a million should be put offshore.
Me: I've never had a million. Right now I don't even have a thousand dollars spare.
Him: You don't? how dreadful for you. But that doesn't affect my point.
Me: Most people don't have a spare million lying around
Him: Sure they do. Everyone I talk to does. And I consult widely.
Me: Perhaps everyone who can afford you does. But trust me, most of the human race doesn't.
Him: How extraordinary. Well certainly everyone who matters does. Everyone who cares about Swiss bank accounts, for example.
[At the Pink 2010 conference, in a CMDB panel discussion, someone mentioned 700 IT staff, so Chris Dancy asked how many of those in the crowded room worked for a company with more than 700 IT staff. Just about every hand in the room went up.]
Me: Sure. Fine. But can you please stop saying "everybody needs a Swiss bank account" because that's simply not true for most of us.
Him: It's much simpler if I just ignore all the unimportant people and keep saying "everyone". Otherwise those who matter might start to doubt.
