Central IT works best as a provider of standards, platforms and guidance, rather than as a preemptor of initiative. Most of the arguments against non-IT development come down to the cost and time of IT going in and taking over a project it did not start — basically, IT does not want the headache.

IT could do this by providing training, frameworks and API’s.
