This is the first part of my fourth lecture at the HITLab, Canterbury University in New Zealand. As a design practitioner I am frequently getting a question from other practitioners, why would they do user research in the first place. Once I manage to convince them why it makes sense, the follow up question typically regards the issue of choosing the right people for that research. In this presentation I am trying to highlight two different approaches to user research, which I will describe in more detail in the next presentation.
