Divide your group into two smaller subgroups. Have group 1 follow the processes specified in this chapter for creating prototypes. Using a CASE tool or a word processor, group 1 should devise two nonworking prototype screens using the information collected in the interviews with Maverick Transport employees accomplished in the group. Make any assumptions necessary to create two screens for truck dispatchers. Group 2 (playing the roles of dispatchers) should react to the prototype screens and provide feedback about desired additions and deletions
