This study explores how organizational learning in subunits affects outflow
s of knowledge to other subunits. Three learning processes are explored: Co
llecting new knowledge, codifying knowledge, and combining old knowledge. T
he results suggest that collecting new knowledge intensifies vertical flows
, of knowledge, that codifying knowledge facilitates horizontal and vertica
l flows, and that combining old knowledge mainly affects horizontal flows.
More generally, the study suggests that uncertainties about the relevance o
f new knowledge are resolved via vertical flows, which (compared to horizon
tal flows) expose new knowledge faster to a wider range of remote and diffe
rent knowledge and thereby facilitate faster, more comprehensive discovery
of its relevance.
