Whilst we were talking about introducing blogs and other social tools to businesses at BlogWalk 4 last week, Dave Wilcox mentioned this diagram
He says on his blog

The point of it is that you need to deal with cultural change as well as technology change at the same time. If you try and bring technology in without commitment from the top, regard to working practices and so on, you’ll get resistance… or lots of systems that don’t work. And if you try and innovate without using appropriate tools you could be frustrated in your purpose.

The diagram was originally developed with colleagues to help contain the enthusiasms a few years ago of nonprofits for the latest technologies, or (more often) to suggest they did have some value.

Dave provides further explanation in his piece, Avoiding the Technology Trap.
