In my previous company we developed a CRM web app for the company to use internally and it was in my humble opinion really easy to make sense of, but for some freaking we kept getting calls whenever someone got an error, and our default response was always to send us an email, then we will get back to you, as it was mostly stupid things they called about, for example, a customer might have to be status terminated, before you can click button A, button A would then be disabled and employees would call asking why. Apparently, people got annoyed by our response and went to the management, to get some guidelines as to when they could call the "development apartment" for help, so the management sends out some guidelines as to when they could call, write or whatever... The following was done without consulting us in any way ANY WAY AT ALL!... Because we all know management knows fucking best, and why bother asking the people that sit with it every day, and the way it was done was by saying:

If the background color on your error is red, it means the error is fatal and you can call the developers immediately, if its orange send an email and they will answer within 48 hours LIKE WTF... Seriously???. That was basically it, and honestly we had just been using colors, without much thought to it ofc red, was an error etc. But they we're not "OMG EVERYTHING IS BREAKING" alert, so we decided to use a couple of hours refactoring the color of the flash errors, and after that, we did not have many red alerts(None, yes none what so ever) We changed all the red ones to orange, and introduced some new colors. That worked for some time around 6 months or so, but then people obviously started calling again like, why even bother... So we created a simple service desk, blocked all incoming calls to our phones that were from regular employees, heard a lot of complaints about this from the employees, management was mad, we had so many meetings with those top paid management fuckers that know everything (way better than you and me), about how to handle this. As it took way too much of our time, that people couldn't bother trying simple things, or make some sense as to why a button is disabled etc. We ended up "winning", was allowed to block calls for some time, till the employees had learned to use a freaking simple service desk, it's not fucking rocket science Okay, stop being a pain in the ass... And it actually fucking worked! Most relaxing time after people got a hang of using the service desk instead of calling life was good after that... <3
