Abstract
A time series study conducted as part of this research confirms psychological aspects related with teamwork on group decision-making. The survey was based on Group Dynamics and focused on Group Process conducted by team members within a team using management simulation. Differences between teamwork awareness were tested statistically according to time series, at the starting point, mid-point and closing point, respectively. A management simulation survey was conducted in 1998 and 80 students answered. In conclusion, the following hypotheses were accepted. Hypothesis 1: Mean of awareness to teamwork has a larger value at the closing point than the starting point (comparison of mean value). Hypothesis 2: Closeness of awareness to teamwork changes according to the time series, and it has stronger unity at the closing point than the starting point (comparison of area and distance depending on the factor loading value position of principal component analysis.) Hypothesis 3: Stratified structure of awareness to teamwork changes according to the time series, and it has a clearer structure at the closing point than the starting point (comparison of cluster analysis dendrogram.)
