The biggest threat I see is an old one, that IT relegates itself to the “glass house” and is not demonstrating how it executes on the companies strategic and tactical imperatives and doesn’t effectively demonstrate its value. It travels under the guise of “alignment” and other buzzwords, but in effect is acting like a shared service versus providing solutions to problems.
The key sign of this failing as I’ve seen it is talking too much about tools in IT; several mentions of “cloud computing” appeared just in this conversation. Imagine if your roof is leaking and flooding your house, and you call a carpenter who keeps talking about the “HammerMeister 4000″ as a response to every question rather than “I can fix this quickly and cost-effectively. Here’s the price, write the check then sit back and I’ll solve your problems without a fuss.”
