Abstract: To design successful user experiences for Google’s communication products, it is important for us to understand their users’ communication behaviours beyond what they do with the product itself. To make informed design decisions, product development teams often require us to build this understanding in a matter of weeks. This paper describes a research technique for building an understanding of people’s social networks and communication tools by only spending 60 minutes each with a small number of research participants. It also describes examples of the type of insights this technique can yield.
