The look for good and bad points of the information gathered. They have the ability look at the over picture. These members usually have an excellent sense of organization. Besides that, DeVito (1985) highlighted other specific roles are distinguished as group task roles. Those roles are opinion seeker, opinion giver, elaborator, coordinator,
