Long term group work by small teams is a central part of many learning and workplace activities. Widespread group support tools such as wikis, version control systems and issue tracking systems are an invaluable aid for groups. They also have the potential to provide evidence for valuable models of the group activity. This paper describes
Narcissus
, designed as a new way to improve group-work by exploiting evidence from use of such group-work tools, to create a visual presentation of a
group model
. The
Narcissus
models and interfaces were designed to help groups function more effectively. It helps individuals see how well they are contributing to the group. It enables groups to assess contributions relative to plans. And it helps facilitators identify problems. The
Narcissus
interface supports scrutability and control over its models. We report a four part evaluation of
Narcissus
:
individual level
with 23 students;
group level
by 5 groups;
facilitator level
with 5 facilitators; and
fine grained study
with 8 students. Results indicate that all these groups were able to understand and use
Narcissus
and that they considered it effective in modelling the group activity in useful ways. They particularly valued the support for scrutability. Key contributions of this work are the creation of a
scrutable
and user controlled group model to support group work and to provide a new form of navigation interface for a complex groupware site.
