Wrong end of the stick?
The IT departments that I've worked for over the last couple of decades have invariably reminded of "Mordac the Preventor" from Dilbert. The author here seems to have been an unfortunate proponent of that philosophy.
A sorry combination of "we aren't going to support it because we didn't write it" with a hefty dose of "we aren't going to write it because we don't think you need it even thought you're asking for it", and a dash of "we'll tell you what you want, how dare you tell us how you do your job".
Yes, jury-rigged apps are dangerous. However, the flip side of the coin is that if people are USING them, perhaps IT should get off its arse and make proper applications with the same functionality actually available. Instead, it was invariably a case for the business end of "better to beg forgiveness than ask permission". With the expected results.
So we have a system where the people on the front line of both IT and the business all know what is really needed, but it has to go through so many layers of management that by the time IT gets a hold of it, it bears no resemblance to what was required in the first place.
We had tremendous success at one workplace with a "semi-official skunk works project office". People on the business end would come up with nifty ideas for apps, someone in IT would hack it together PROPERLY (ie: designed, documented, tested, etc.) but in a minimal-overhead environment with high user involvement, and the user (or small group) would go off quite happy. If the app became popular it was then already in the IT system and it could then more easily be made more robust (having been designed right in the first place) for more extensive deployment. If it died only a few hours of someones time was wasted. The business case was that we were writing prototypes for new apps, and the users were happily testing them.
This system worked very well.
Unfortunately, that system died when the IT dept was outsourced to a large concern with IT "managers" who held their positions more due to their arse kissing abilities than their ability to actually get things done. Suddenly the people in the business couldn't get what they needed, and the company quickly became stupefyingly obtuse in its use of technology.
The team disbanded very quickly, and we went our separate ways. Pity really.
