We ll first introduce a range of techniques, then examine some objectives that usability evaluation might address together with how they ve been applied to real projects. And finally wrap up with a look at other benefits usability evaluation might deliver to your project. User Opinions Users are not always available when you need them. The following techniques require direct input from users, however the amount of time required by each varies. The first three techniques can be done at the convenience of the user, whilst the latter three require specific time with users.
Users write their opinions on sheets of paper mounted along side the screens.
This technique must be done at the user worksite. Document reviews involve users reviewing and commenting on functional requirements and external design specifications at their convenience. Bear in mind, however, that a functional requirement may not be entirely comprehensible to your user group as they are not systems designers. One way to help them envision what a final design might look like within a familiar context is by writing an activity scenario and illustrating it with sample screen designs. These illustrated scenarios serve to communicate the design and how it would work within the context of use.
