It keeps happening - Let me give you an example: I was sitting in a Board presentation of a CIO's budget, and the CIO said: We need 2 million year week for DR. One Board member leaned over and whispered to another: "What's DR?" The other paused for a moment and said: "Oh, that's BCM." and both sat back with comfortable looks on their faces.
So the IT Disaster Recovery budget was approved, but at least two Board members thought they were getting full Business Continuity Management for their money.
Now the fault lies in part with the Board members for not clarifying the issue, but I've sat in enough Board meetings to know how much political ego is invested, so no-one was going to ask the stupid questions. And the problem should not have arisen anyway.
I spend a lot of my time advising CIOs on their IT budgets, and how to communicate their budget requirements in ways that business people understand. I failed in this instance, but the CIO was big enough to follow up her poor communication effort with an e-mail to the Board members explaining what DR was, and pointing out that it was definitely not BCM.
In another case, I was called by a CIO in a panic who said: "I've just been told by the finance committee to cut my budget by 20%, and go back next week with how I'll do it And I can't do it - the business will suffer."
