This article argues that the success of international strategic alliances r
equires attention not only to the hard side of alliance management (e.g., f
inancial issues and other operational issues) but, also, to the soft side.
The soft side refers to the development and management of relationship capi
tal in the alliance. Relationship capital consists of the socio-psychologic
al aspects of the alliance that are positive and beneficial to the alliance
. Two important areas of relationship capital are mutual trust and commitme
nt. Based on our findings from two major studies of Japanese strategic alli
ances, we develop a dynamic model of trust and commitment based on mutual a
djustments of alliance partners. We also show how the dynamics of trust and
commitment affect the performance of international strategic alliances wit
h the Japanese. The article concludes with a discussion of the managerial i
mplications of our findings and the dynamic model.
