Groups use different procedural structures to organize their efforts in group meetings. These structures are affected by the group members' preferences for the degree of procedural order they want in a meeting, as well as by the communication media available in the meeting environment. Analysis of thirty partially distributed experimental groups that met over a period of time indicates that members' preferences for procedural order affect their perceptions of outcome satisfaction and participation. Further analysis of video tapes of the sessions should indicate how media and other factors affect the members' actual attempts at providing structure to the meetings.
