(b) Why is it harder to evaluate groupware than single user systems?

answer available for tutors only

(a) Answer should define situated action. Context is vital since it is part of the activity of the group. Cooperation is dependent on the formation of groups, which cannot happen properly out of context. Evaluation must assess support of cooperation and must therefore consider context.

(b) Should refer to choice of method, context and situated action, variation within as well as between groups, the complex issue of who benefits. Should discuss possible solutions - any reasonable ones acceptable - perhaps extending methods such as cognitive walkthrough, or using ethnographic methods.
