I think that's the lesser problem. The bigger problem is the attitude of IT is wrong from the start. When they start doing something, they want to Do It Right. They want to automate the business process. But that's the wrong goal! You can spend years doing that and go all the way to building a homegrown SAP, and it will still suck and people will still use their half-assed Excel sheets and Access hacks.

IT should not be focusing on the theoretical, platonic Business Process. It never exists in practice anyway. They should focus on streamlining actual workflow of actual people. I.e. the opposite advice to the usual. Instead of understanding what users want and doing it, just do what they tell you they want. The problem with standard advice is that the thing you seek to understand is emergent, no one has a good definition, and will change three times before you finish your design doc.

To help company get rid of YOLOed hacks in Excel and such made by interns, IT should YOLO better hacks. Rapid delivery and responsiveness, but much more robust and reliable because of actual developer expertise behind it.
