It wasn't that I didn't know the stuff, I do, but more helpful with quickly organizing and presenting information in a clean and well-written way. I did have to go through and re-write parts of it specific to our domain.. but it saved me many hours of work doing tedious organization of data.
I also tested it with helping create some SOP's for a new position in our very small company, even breaking down the expected tasks into daily schedules.
It's not that it's perfect, but it generates a bit of a boiler-plate starting point for me which then I can work with from there.
