Interview
Can change script to suit circumstances / questions can be explained / repeated /
interviewer can interpret body language
Observing
Can gain broader overview of processes / saves workers’ time / can gain a more
accurate view of what is happening
Examining documents used in current system
Can follow data flow more easily / informs input / output format design
Distributing questionnaires
Better for busy people / don’t have to prearrange appointments / more honest as
they are anonymous / takes less time to get all the results (compared with e.g.
interview)

these are only the advantages
