As a student you have probably mo money you can offer as compensation. So at least you should offer some coffee and cookies to your interviewees! | As a student you have probably mo money you can offer as compensation. So at least you should offer some coffee and cookies to your interviewees! | ||
The important thig about the interview is that you | The important thig about the interview is that you ''don't'' ask specific and direct questions but open ones. So the answers you should aming for are not "yes" or "no" but e.g. the ones the user can tell you experiences or explaines you something. Often it will be usefull to follow up something the user said. Asking why a decision was made in a specific way or how something works can reveal important facts. | ||
Here are some open Questions as an example | |||
* What motivates you to do this? | |||
* What was the best day at work in the last weeks? (Follow up with "why?") | |||
* What annoys you when you work on this? | |||
When you do interviews there are some common problems that can occur. | |||
# '''You ask "yes/no" Questions''' <br> | |||
You: ''"Do you like this mobile phone?"'' Interviewee ''"Yes!"''<br> | |||
What do we know now? Nothing.<br> | |||
Solution:''"What do you like about the phone?"'' | |||
#'''The Interviewee answers in very abstract ways'''<br> | |||
Interviewee answer: '''"In general these things make me think about..."''' <br> | |||
The answer does not tell us something interesting about the real life of the user. <br> | |||
Solution:''"Can you tell me about the situation it happened the last time?"'' | |||
#'''The Interviewee demands a specific feature'''<br> | |||
Interviewee answer: '''"Well... You just need to put a red button here!"''' <br> | |||
Users don't know what would make a design that is good to use for everybody. We dont know either for sure, so we do research!<br> | |||
Solution:''"How would the red button help you?"'' | |||
#'''You want to know if a feature you have in mind would be good'''<br> | |||
You: '''"Would it help you to have a green lever that does [whatsoever]?"''' <br> | |||
This is similar to the situation above. What the user understands will be just "...help you?" or "...feature..." so help and features are considered as good so the answer will be ''"yes"''!<br> | |||
Solution:Don't ask this question! It would be more useful to gather informations about the user and his/her context that could reveal if the user needs the feature that you have in mind. | |||
State clearly that you do an interview for doing research for an design project. | |||
