I wish every IT worker I hire thought like that. There’s no substitute for doing it in house. Not only do you get the institutional knowledge your people are actually interested in their jobs. It’s a larger up front cost (I just approved a $1500 training course last week for 2 of my people) and it takes them somewhat offline for a while but every dollar you invest in learning is paid back tenfold or more and ultimately the stuff isn’t crashing every day.
Besides, I’m at the point where most of the vendors I outsource anything to, can’t teach me anything. Their main use is getting something done faster since I can work them in parallel, but usually not better.
