This paper outlines two leadership strategies to support organizational learning through networks of practice (NOPs). An in-depth case study in a development organization reveals that network leaders cope with a learning tension between management involvement and emergent learning processes by enacting two strategies: brokering and buffering (B&B), or conducting and controlling (C&C). The latter strategy implies a one-sided emphasis on institutionalization, whereas a B&B strategy implies mediating and shielding the network from too much management intervention. The B&B strategy appears more useful for achieving multilevel organizational learning through NOPs; this study thereby contributes to theory about learning and NOPs. © The Author(s) 2011.
