Effective design of digital workplaces depends, among other factors, on the nature of the workgroup involved. Therefore, gaining a deeper understanding of workgroups helps in identifying the different requirements they have regarding their workspaces. In this paper, we present the findings of a study to identify key dimensions used to describe and characterise workgroups and examine their implications for workspace design. Through a thematic analysis of the academic and practitioner literatures on workgroups and using qualitative data coding methods, we identified two broad categories and ten distinct dimensions: structural and organisational (size, longevity, accountability, purpose, membership, leadership and formality) and work types and working style (work product and outcomes, interdependency, activities and meeting culture). Based on these findings, we identified three cross-cutting themes regarding the implications for the design of digital workspaces for organisational workgroups: Workspace Assembly and Tool Affordances, Information Design and Content and Coordination and Awareness Mechanisms.
