In the current turbulent business climate, teamwork is the ultimate co
mpetitive advantage (Tjosvold, 1991). In an attempt to achieve better
teamwork some organizations have turned to adventure-based experientia
l training (ABET). This study evaluates outcomes from a case study of
one particular ABET provider and examines what factors might affect su
ch outcomes. A total of 157 individuals, randomly assigned to teams (n
= 20), attended a residential ABET programme. The outcomes, measured
in a pre- and post-test design, were perceptions of team effectiveness
and perceptions of personal benefits derived from the training. Overa
ll, results showed that there had been no improvements on both of thes
e measures. However, this concealed significant variation between team
s, with some teams improving while others deteriorated. Four moderatin
g variables were considered to explain this variation: the team 'make-
up' in terms of learning styles and team roles, neither of which expla
ined any variation; and the weather and the team's position in the sta
ged competition, both of which were found to predict outcomes.
