This is a practice that looks to visually map out commonalities between members of the team or organization. It provides a map of how each person relates to one another. The goal of this practice is to create a spark for follow-on conversation between folks who may not have met before or deepen the relationship for those they have met.
When new teams are forming, or there is a need for a team to form better relationships with one another, this practice can provide an easy way to begin that journey. The safe space it can provide only needs to go as deep as the two people creating the connection want to go, and does not discriminate those more extraverted or introverted. While the desire to form a relationship with the entire team, you may find yourself more connected to some and less connected to others. That is okay and understanding the level of comfort between two people is a step to understanding personal boundaries before they come up as an issue.
