The Art of Facilitation: Building Trust and Psychological Safety in Design Teams

Abstract

Abstract. Engineering design often relies on teams to maximize creativity and problem-solving potential; yet, complex social dynamics often limit team effectiveness. Prior work has recognized the importance of trustworthy facilitators and a favorable team climate, but little research has examined the specific behaviors facilitators use to foster these relational conditions. Leveraging data from a Design Thinking workshop, our exploratory in situ study investigated facilitators’ behaviors and their impact on team dynamics. We developed first-order Markov models to investigate conversational patterns between facilitators and team members. Similarities across models revealed interaction patterns despite group differences. High transition probabilities between facilitators’ engagement in the design task and both team engagement and support suggest that facilitator involvement fosters a collaborative atmosphere. The transition from facilitator clarifications to team questions underscores their role in promoting shared understanding. To explore how facilitators’ behaviors aligned with team members’ perceptions of facilitator trustworthiness and team psychological safety, we analyzed correlations between these factors. Facilitators who more frequently built rapport, prompted reflection, or engaged in the design task tended to be rated as more trustworthy, whereas more frequent questioning was associated with lower perceived confidence and expertise. Team members also tended to report higher psychological safety when facilitators worked collaboratively alongside them. These findings offer insight into the behavioral mechanisms that support effective facilitation and identify behaviors that meaningfully shape perceptions of trustworthiness, team climate, and conversational dynamics in engineering design teams.
