How long have you been at the company? Did you just join? I ask because no company is perfect. The hardest part which is what many comments seem to be saying is figuring out the "real" problems.

Let's take documentation. I tend to be the person who onboards people for source control. There is indeed a document buried in previous version of SharePoint that was not migrated to the new SharePoint. We only get new a couple new employees a year so it is just quicker for me to have a 30 minute session with new employees than to figure out how to migrate all the documents from the old SharePoint site. The 30 minute session is better than any documentation I will ever write. New employee gets to ask questions and so on.
