Abstract
Much research exists regarding (computer-supported) idea generation, yet little is known about how teams can be facilitated to efficiently converge on a set of ideas. Convergence is a critical activity in collaborative problem-solving and decision-making as teams need to focus their cognitive resources on the most promising ideas resulting from a brainstorming activity. This paper investigates the effects of facilitation on team outcomes to foster our understanding of convergence. We tested three facilitated convergence techniques, Self Sifter, Fast Focus, and Treasure Hunt that offer different levels of procedural structuring and discussion allowances. An experiment with 138 subjects in 34 teams showed significant improvements in satisfaction with process and product after convergence. Self Sifter and Treasure Hunt outperformed Fast Focus in terms of shared understanding, while Fast Focus and Treasure Hunt outperformed Self Sifter in terms of usefulness of moderation. Our findings contribute to a better understanding of how teams can benefit from facilitated convergence techniques.
