Coloured post-it notes were used to represent Geography (yellow), Visualisation (pink), and Provenance (orange) and white ones for interests that applied to more than one theme. The entire team agreed upon the fact that their interests in geography, visualization and provenance often overlap. In the end, everyone had contributed to each of the themes. We ended up with four walls for post-its with key interests and very often challenges
After lunch, everyone was invited to examine their contributions closely and to decide their first and second preferred group choice; fortunately, almost everyone was grouped within their first choice, and the result was three very balanced groups.
