Effective coordination is essential for any group work and has been studied widely in the fields of Management Science and Organizational Behavior. A classic definition of coordination is “the management of task dependencies” as proposed by Thompson [16], who distinguished among pooled tasks, where the results of individual actions are simply aggregated; sequential tasks, where the output for one is the input for another; and reciprocal tasks, where work flows back and forth between tasks. More recently, Malone and Crowston [12] developed detailed catalogs of general types of interdependencies that occur across many domains, and particular types of dependencies that occur only in specific domains.
