Abstract

Cultural diversity has long been acknowledged as a defining feature of contemporary teams, particularly in globalised work environments. In recent decades, cultural diversity has attracted growing attention within academic research on team dynamics and performance. However, the existing body of literature remains diverse, methodologically disjointed, and conceptually inconsistent. Limited attempts have been made to synthesise qualitative findings in a way that captures the complex interplay between diversity and team performance. Thus, the field will benefit from a holistic and process-oriented understanding of how cultural diversity shapes team outcomes. This study aims to address this gap by conducting a qualitative meta-analysis of empirical research on cultural diversity in teams across different sectors. Specifically, it seeks to synthesise thematic insights across studies, highlight recurring patterns and barriers, and identify directions for future research. The study is guided by two interrelated research questions: (1) How does cultural diversity influence team performance, especially team dynamics and communication? and (2) What are the key mechanisms of cultural diversity that impact team performance, especially on team dynamics and communication? To achieve these objectives, a meta-synthesis method was applied, drawing on twelve peer-reviewed qualitative studies published in the last 10 years. Thematic synthesis was used to identify and cluster key patterns across studies, progressing from primary-cycle coding of participant quotes to higher-order conceptual categorisation. The analysis was conducted inductively, and the resulting themes were interpreted through the Input–Process–Output (IPO) model to contextualise how cultural diversity shapes team inputs, interactional processes, and performance outcomes. The findings reveal that cultural diversity impacts team performance through relational, structural, and practice-based dynamics. Eight core themes emerged, grouped into three overarching conceptual categories: Relational Conditions that Enable Inclusion, Structural and Normative Barriers to Inclusion, and Practices that Translate Diversity into Performance. From this synthesis, the concept of Cultural Attunement was developed. Cultural Attunement is a process of cultural negotiation and relational reflexivity that allows diverse teams to build trust, adapt meaningfully, and optimise collaborative performance. This research makes several contributions. Theoretically, it advances a process-oriented understanding of cultural diversity by proposing Cultural Attunement as a central mechanism in diverse team functioning. It also bridges fragmented strands of literature by offering a cohesive thematic framework grounded in lived team experiences. Practically, the findings offer actionable insights for leaders and organisations seeking to foster inclusion and leverage diversity. Finally, the study proposes future research directions, including longitudinal and ethnographic approaches, to further examine how cultural attunement develops in real-time, high-stakes team environments.
