What Did It Mean to Bring Inner Source to an Enterprise?

So many know the drill - a centre of excellence is stood up, some code and recommendations come out of it, nobody really uses it, and it's back to the usual in a year or so. It happens very often in large enterprises trying to reinvent the engineering function. With this session, I am not here to complain or talk about failed attempts. I want to talk about an actual success story that absorbed over a year of my life (and it's still ongoing!), which led to a well-oiled Inner Source product in a large enterprise as well as a number of examples of collaborative development in a non-IT organisation. It's been a journey, long and with mistakes, however successful in the end! Let's see how.
