Because communities of practice must be self-organizing to learn effectively and because participation must be intrinsically self-sustaining, it is tricky to use reward systems as a way to manipulate behavior or micro-manage the community. But organizations shouldn't ignore the issue of reward and recognition altogether; rather, they need to adapt reward systems to support participation in learning communities, for instance, by including community activities and leadership in performance review discussions. Managers also need to make sure that existing compensation systems do not inadvertently penalize the work involved in building communities.
