Next, you must be wary of culture eroding as your organization grows. Consider Dunbar’s number—150—which is the maximum group size at which a stable, cohesive social group can be maintained. (It’s named after anthropologist Robin Dunbar.) The idea behind Dunbar’s number is that at about 150 group members and below, you can relatively easily know everyone in the group and their roles within it. Above this number, however, you cannot easily remember everyone and what they do.
