Sitting with the developers is, as you say, a way of reminding them of the documentation/user education needs, I fear that without that reminder they will fall back to the habit of whatever is easiest for them (ie. NOT remembering).

May sound harsh but that’s what has happened everywhere else I’ve worked. It’s only now, sitting the writers with the team they are working with, that they seem to realise how important the documentation is.

But hey, happy to be proved wrong!
