Conclusions
ìÖmany of the serious problemsÖstem from a culturally prevalent, easy-to-make assumption that communication consists of bits of verbal or textual material passed whole from one person to the next.î - i.e., the Parcel-Post model conflicts with real-time collaboration.
Must examine what working in parallel means in order to support it properly.
Familiarity with the system appears to ameliorate some of the problems - I wonder what performance would have been like after many hours of training.
