The goal of this study was to examine individual, relational, and organizat
ional determinants of negotiation behavior (problem solving, contending, yi
elding, and avoiding) between planning and marketing departments in manufac
turing organizations. Results from a study among 41 managers and 85 plannin
g and marketing employees within II firms showed that individual personalit
y, perceived interdepartmental interdependence, and organizational strategy
were each related to the negotiation behavior of department members. Desir
able negotiation behavior-specifically, the problem-solving approach-was mo
re likely when individuals were extraverted and agreeable, when employees p
erceived high interdepartmental interdependence, and wizen organizations di
d not have a low-cost strategy. Contending was more likely when individuals
were extraverted and disagreeable, and yielding was more likely when depar
tment members perceived a power advantage vis-h-vis the other department. A
ll four styles of negotiation behavior were more likely the less the organi
zations had a low-cost strategy. These findings provide guidance to organiz
ations in their efforts to encourage constructive negotiation behavior betw
een departments.
