Constructive Interaction: An Analysis of Verbal Interaction in a Usability Setting

This paper focuses on the interaction between teams of participants in the constructive interaction (CI) method. We analyzed transcripts and video recordings from five CI sessions in order to determine the types and frequencies of communicative acts performed as well as their usefulness to usability testers. In addition, we examined the contribution of the individual team members to the interaction and investigated whether the interaction took place according to a pattern of cooperation. Our analysis showed that team interaction in the CI test is highly task-oriented and hardly descriptive. For the most part, the five CI sessions contained communicative acts that are (potentially) useful to usability testers. The contribution of the team members to the interaction was largely similar in terms of types/frequencies of communicative acts, but the teams' cooperation pattern revealed that this equal contribution was no immediate guarantee for successful cooperation. To address this issue, we suggest several ways to improve the CI method
