No matter what the project is—from an exciting Internet of Things innovation to a data center migration—the IT department needs money to pay for it. But IT, all too often, does a lousy job of communicating its needs in language the financial and executive types who decide on the budget really understand.

You can argue that this is because financial officers and executives don’t understand IT as well as, say, manufacturing. You can argue it’s because IT managers tend to speak geek at budget time. Whatever the reason, the onus is on IT managers to fix the problem because they’re the ones who want the money.

“The failure is on the side of IT for not learning to understand the customer properly and thus not being customer-focused.” says Dave Chesworth, a consultant and project manager based in Manchester, England.

All too often, non-IT managers lack a clear understanding of how the money in the IT budget affects the rest of the company. In the words of Jim McGittigan, research vice president at Gartner, the IT budget is “a necessary evil and a $300 million black hole.” McGittigan stresses that his positions are his and not Gartner’s, but others echo his observation.
