Here, we will go through the considerations you should make when deciding what type of research participants you want and give you pointers for how you can go about recruiting the participants you need so as to make your project matter far, far more to the real users later.
If you have a broad target group, you can use design consultancy IDEO’s method of recruiting both ‘Extremes’ and ‘Mainstreams’.
By including extreme users, you can be more confident that your research covers the entire spectrum of your target group.
Often, you just need to recruit participants who represent your primary target group and you don’t have to cover every corner case you can think of.
Your actual usership is likely to end up involving more than just a few unexpected types of users, anyway.
