Qvest is designed to support meaningful conversations about important topics.
For participants to have a meaningful conversation they must feel committed and connected to their co-participants.
According to anthropologist and evolutionary psychologist Robin Dunbar, 150 is the maximum number of individuals with whom people can maintain stable relationships "that goes with knowing who they are and how they relate to us" (Grooming, Gossip, and the Evolution of Language).
That's why we encourage you to remember these four rules of thumb:
With less than 20 people, there is a risk that the conversation will dry out in a couple of days.
With 20-150 participants, the odds of a successful Qvest are great!
With more than 150 participants, you might need some extra communication to motivate your participants to contribute.
With more than 500 participants, there is a risk that you cannot reach and motivate all your stakeholders in the same Qvest.
Remember, if you have more than 500 stakeholders, you can design and run multiple Qvests - and then cross-analyze and compare the output.
