| If private issues are important: one-to-one interviews | ||
| List of Functions | Group focus session | Group focus session |
| Which function can be left out, or deferred? | Questionnaire on value of functions | |
| Task Design | Is planned workflow practical? | Mock-up walkthrough |
| Group focus sessions | ||
| Are there steps missing or improvements needed? | Group focus sessions or on-the-wall method | |
| High-Level User Interface Structure & Visual Metaphor | Is it obvious what the system does? | Protocol simulation Describe the system and each object |
| Can users find the functions? | Protocol simulation For each function, where would you find it? | |
