You are using IT as synonymous with Support/Helpdesk. Do you have an enterprise architect, do they report to the CIO? Maybe its the COO? Do you not consider systems architecture a part of your IT department?
I absolutely think you are wrong that innovating is derived from your needs, a technology group driving innovation could just as well include obsoleting you. An IT department can bring new business ideas to a leadership team, and arguably their leader is a part of that leadership team, at least until every c-suite person is tech savvy enough to obsolete the CIO position.
I am using IT to refer to more than support/help desk. It includes, for example, having a working network, email, and CRM. It includes custom database applications. It includes an internal wiki and an external web site. It includes lots of other things.
All of those things are there to support the business, not the other way around.
