The role of the organization's resources and capabilities in its competitiv
e advantage, and, by extension, its performance, has become a topic of rene
wed interest. Although the importance of capabilities is the basis of much
of this research, there is little work which investigates how capabilities
are actually created. This paper empirically assesses the role of managemen
t in the creation of capability within organizations over time. Of five hyp
otheses, two were fully supported, and partial support was found for a thir
d. We find that managerial advocacy in the form of specialized directors of
sub-units, and the number of executives on the top management team, influe
nce capability creation as does the existence of formalized rules related t
o resource allocation. CEO background was found to have no effect. The resu
lts present the initial outlines of how competencies might be created and s
uggest avenues for further inquiry.
