Abstract: This study seeks to find the team work dynamics and the critical communicative issues in the design process of RCIDS. The purposes are: (1) the participation and commitment shall affect the performance of the teamwork and (2) the participation of the individual team member is dependent on the positive appreciation and acceptation of the other members. Two separate design teams with the RCIDS were tested and observed successfully. Five issues were concluded: (1) Motivation and commitment: team members become more committed when their design ideas were accepted; (2) Team management: the team with ideal `all type` networks dynamic tends to have better design outcome; (3) Communicative issues: team dynamics focuses on the issues of modification, suggestion and description turned out to have better design result than the team on other issues; (4) Peak hour: two main preferable time, one is between the hours from 9-18 and the other from 21 h till next day on 3-4 h; (5) Deadline effect: the communicative frequencies before or after the deadline are higher than other dates in average.
