Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by domain experts without the ongoing support of external collaboration professionals. Since 2001, CE has been an active and productive topic of research that has attracted scientists from different backgrounds and disciplines. CE research started with studies on ways to transfer professional collaboration expertise to novices using a pattern language called thinkLets. Subsequent research focused on the development of theories to explain key phenomena, the development of a structured design methodology, training methods, technology support, design theories, and various field and experimental studies focusing on specific aspects of the CE approach. This paper details the contributions from CE research and practice based on a literature assessment of 331 publications. It extracts the key insights from the body of CE research thus far, identifies significant areas of inquiry that have not yet been explored, and looks ahead at the CE research opportunities that are emerging as our society, organizations, technologies, and the nature of collaboration evolve.@en

When very large groups have to brainstorm in smaller subgroups, meeting organizers have a choice between two options: (1) Let every subgroup start from scratch, or (2) Let every next subgroup build on the results from the previous subgroup. We refer to these options as the Decathlon and Relay modes of brainstorming respectively. During a case study we investigated which brainstorming mode would be more productive and result in higher levels of participant satisfaction. Consistent with the hypotheses, Relay groups appeared to be more productive than Decathlon groups, in particular in terms of elaborations to previous contributions. Relay groups were also found to be more satisfied. This study also introduced the elaboration coefficient, an indicator to quantify the amount of task relevant discussion in brainstorming groups. The results of this study hint at a number of meeting design guidelines for very large brainstorming groups.@en
