Date of Defense 1997-04-10 Availability unrestricted Abstract Organizations increasingly use work groups to
perform process improvement tasks. Little
research exists about groups assigned
complete tasks such as process improvement
which involves completing all group processes,
such as: generating, selecting, negotiating, and
executing. This research tested the impact of
decision aids on work group processes and
work group performance. Laboratory and field
experiments were performed. Decision aids
were shown to impact work group processes.
Decision aids increased the number of ideas
considered by the work group, increased the
equality of participation in the work group,
decreased the overall level of conversation,
and reduced consensus during evaluation of
sensitive issues. No significant difference was
found between decision aid types and work
group performance. A regression model was
identified which predicts group performance.
Two variables were high predictors of work
group performance: the level of conversation
occurring in the group and the range between
high and low idea contributors. The range
between high and low idea contributors was
correlated with the skill level of participants in
the group.
