Early on, it's meant spending months on implementation, hand-holding the first few users so they can become evangelists within the company. It's not a lot of work, it's just over a long period of time.

I track usage metrics every day and routinely message power users to ask what may be keeping others from adopting, asking non-users if they've been trained, and asking execs if they have evangelized from the top down.

So, you have to hit everyone over a long period of time.
