The reasons why differ very differently from organisation to organisation in my point of view.
It can be a way that other departments want to deliver IT solutions without the red tape of IT (change management, validations etc). This allows them to deliver solutions faster with less validation layers. Of course this comes with its own set of risks.
Another possibility is a "project" that started with a business driver and end up having IT profiles developing solutions.
The bigger the company the harder is to track these cases.
Finance has oversight on budget and expenses. If IT invoices are coming from non-IT departments, at very least, it should raise alerts.
In the end is a senior management guideline, on how serious they want to avoid shadow it. Honestly, in some cases I saw them creating these situations for avoiding hurdles from IT processes.
This is a very typical and common situation. Why does it occur? How can we prevent this?
