Collaboration is a hot issue, and is to an increasing extent recognized as a key driver of overall business performance. However, few companies methodically evaluate how well they perform in the area of collaboration, and few companies have implemented management principles to systematically improve collaborative performance. The research described in this paper indicates that there is a mismatch between the potential impact of collaboration on business performance and the attention given to collaboration, in particular in terms of investment in tools and methods supporting collaboration involving tacit interactions and tacit knowledge work. This paper highlights a few important dimensions of collaborative work, and suggests a few action points for organisations that are interested in improving their collaborative performance and obtaining a higher Return on Investment (ROI) on their collaboration initiatives.
