We try to use a Community of Practice framework, e.g. https://en.m.wikipedia.org/wiki/Community_of_practice. Active members of a CoP might then decide to set up a book club etc.

It's quite easy to draw a line from org principles ("we're always learning" etc) to active participation in a CoP, so helps align incentives on a team level (we can spend time on things outside of our immediate needs) and an individual level (it's an obvious way to get performance review evidence)
