Group communication is a very difficult task to be implemented in distributed applications. Particularly, work management systems are important in many industries to support the coordination of distributed groups of mobile workers with different levels of availability. Traditional event-based systems using point-to-point communication such as e-mail are not well suited to coordinate a work group as the state of a work item is not always clear and this mode of communication creates many mistakes and massive communication overhead because those tasks are solved via a central server. In this paper, we analyze a work process in a major insurance company, develop a prototype providing solutions for the problems by exploring the coordination features deployed in spacebased computing and compare the current system with the prototype.
