Abstract
The use of the Internet and mobile communication service has been common in the business, and the way of working has been dependent on the communication tools used. The selection of communication tools becomes more important as the quality of communication in a group depends on the selection of communication tools including face to face. This paper proposes "Media Fitness Framework" through which the degree of fitness between a task and a communication media can be determined by measuring rational, social and environmental aspects of the communication. It then shows some sample analysis of a group in the distributed work environment which has become common these days.
