Twenty-three cases of international negotiation are analyzed and compa
red to better understand the role of analytical and informational tool
s in supporting practical negotiators. For each case, data were gather
ed through interviews with Austrian diplomats on the type and amount o
f analytical support provided, associated bureaucratic support, and pr
oblems encountered along with a host of key factors about the case its
elf-the issues, situation, strategies, process, structures, and outcom
es. These data were coded and analyzed statistically. It was found tha
t most analytical support is qualitative in nature and can be categori
zed as information organizing tools, comparison methods and creativity
techniques; economic negotiations, in particular, tended to be suppor
ted more by quantitative methods, including forecasting and statistica
l models. Analytical support is particularly important to understand o
wn and other side positions and strategies and to bolster complex nego
tiations that require issue packaging. A generational gap between seni
or and mid-level diplomats emerged: junior practitioners expressed a g
reater interest in analytical support tools. In general, the applicati
on of analytical support was perceived positively among practitioners
and was correlated with the achievement of treaties and comprehensive
solutions. These findings suggest that there needs to be greater inves
tment in developing and providing practical analytical support to nego
tiators, more supporting infrastructure to facilitate the use of these
techniques, and increased training opportunities.
