A procedural framework for fostering team mental model sharedness through co-design approaches in information visualization projects

Abstract

This study investigates how structured co-design approaches foster team mental models (TMMs) sharedness in interdisciplinary design teams engaged in information visualization projects. Interdisciplinary collaboration faces challenges including communication barriers, diverse domains and complex informational environments that hinder shared understanding and cohesion. Drawing from literature on team mental models, team cognition and co-design practices, the study formulates four research questions related to specific interventions, integrative activities, evocative artifacts, framing guides and guided reflexivity. An exploratory mixed-methods approach involved two design teams through brainsketching workshops, with one experiencing structured co-design interventions and an unfacilitated group without interventions. Data analysis integrated qualitative verbal protocol coding with quantitative transition matrices to capture sequential interaction patterns. Chi-square analysis revealed distinct behavioral patterns, with the intervention group exhibiting richer communicative sequences. Findings reveal that integrative activities enhanced early team integration and supported divergent thinking. Evocative artifacts facilitated semantic alignment and novel idea development, while framing guides helped establish adaptive decision-making. Guided reflexivity encouraged procedural strategies around complex problem spaces. The unfacilitated group experienced difficulties, particularly in task framing and reflection processes. This research contributes a procedural framework mapping verbal activity types to team cognition stages, offering approaches for fostering TMMs in interdisciplinary design contexts.
