Techniques for developing commonality among individuals can include running primers for people new to ed tech, explicitly bringing multidisciplinary perspectives to bear on tech issues, having common problems to address, crowd-sourcing principles, and so on.

The approach is to reach some form of consensus, but that consensus itself is fluid and changeable, varying over time and location, just as the contents of the suitcase will vary depending on specific trips.
