The aim of design research is to gain insights, create empathy and to inspire solutions. Therefore, the goal of the analysis is to come up with materials that support this.
After research activities, I debrief by writing down my first impressions and insights. Later, when going through the research data, I write down quotes and observations on post-it notes. Using affinity clustering I would then start to synthesise all data and write down initial insights. I find that this process can be repeated several times to narrow down and distill the core and that working in a group is ideal for this process.
Besides these textual insights I like to use visual models and personas to understand and emphasize with the target group.
