Considers the relationship between the perceived quality of discussion
within a group and that group′s performance on a marketing
decision‐making game. Reviews the relevant literature and discusses an
instrument for the measuring of perceived quality of discussion within a
decision‐making group. Evaluates the structural ramifications of the
instrument with relevance to a study of 95 MBA students playing a
marketing decision‐making game in groups. It was found that, with one
exception, the instrument maintained its underlying structure as a
measure of perceived quality of discussion within a group. With regard
to the faculty of the behavioural variables within the instrument to
predict overall unidimensional perceived quality of discussion within a
decision‐making group, it was found that, while significant prediction
was still maintained, fewer behavioural variables were significant in
the regression model. No relationship was found between the perceived
quality of discussion in a decision‐making group and the profit achieved
by that group.
