EXERCISE 9.9 [extra - not in book]
Which evaluation methods do you think are most appropriate for group systems? What particular issues do evaluating group systems raise?
answer available for tutors only
This is a question where there are many possible answers but appropriate methods to discuss include ethnography and field based longitudinal studies, for assessing how group systems are actually used; and possible extensions to CW and heuristic evaluation to assess elements of the interface. The issues to be considered include the choice of method - adapting methods to suit groups; variation within as well as between groups, complexity of who benefits from the system and conflicts of interest. Context is also important. Co-operation is dependent on formation of groups, which cannot properly happen out of context. Evaluation must assess support of co-operation and must therefore consider context.
