The system need to be easy and people that have question can search Inside the FAQ. Why asking when you can search for that damn process, guideline. I check slak and the first that I see is a personn asking if he can bring the dog or cat at work. Who is stupid enough to ask these question and ask for something that he should know where it is. But no ask people for that they give shortcut, link. So much value added!

It's almost the same with email, people have never been trained and still send file over and over, don't communicate with the whole team, you need to push and ask the information because it's a nice tool but not correctly used.
