One view holds that organizations are virtual to the extent that they outso
urce key components of their production processes, and that electronic netw
orks make if easier to do this. The goal of the present paper is to examine
explicitly the effects that use of electronic networks for transactions wi
th suppliers has on firms' degree of virtualization. In so doing, we also h
ighlight factors that influence the use of networks for coordination with s
uppliers, and the impact such use has on coordination success. Contrary to
much recent speculation, the use of electronic networks for transactions wa
s not associated with increased outsourcing, but rather with greater depend
ence on internal production. Moreover, the use of interpersonal relationshi
ps for coordination, which many think of as an alternative to electronic ne
twork use, was positively associated with greater network use. Surprisingly
, use of electronic networks was negatively associated with such outcomes a
s order quality and efficiency, and satisfaction with suppliers, while more
reliance on personal linkages was associated with better outcomes and miti
gated the negative consequences of using electronic networks.
