1. Make sure you’ve got a lot of wall space.
2. Whatever kind of information you have on your sticky notes, make sure there is one point per note.
3. Put the sticky notes on the wall, reading each one aloud as you do.
4. Each time you put up a new sticky note, ask yourself if it’s related to or similar to a previous one. Place it near the existing note. If it’s exactly the same, place it behind.
5. When all the sticky notes have been clustered, write a title for each cluster on a larger sticky note.
6. Review the outliers: they may belong in smaller clusters.
7. Your clusters are now your themes. You may want to prioritise them according to their importance.
