When you talk about change or optimum team sizes, Dunbar’s number is usually thrown down as scientific evidence of something you already know in your bones. Shit gets weird somewhere between 100 and 200 people. You can no longer keep the individual state of each of the other people in your team or company in your head. Which means communication becomes more taxing. Rather than walking up to Fred and saying, “What’s up?” you cautiously walk up to a person you don’t know and sheepishly ask, “Yeah… who are you?”
What was easy becomes hard. What used to be maintained in your head now involves an extra email or an additional meeting. What was familiar becomes unfamiliar and frustrating. Culture is diluted, communication becomes taxed, and people start saying, “I remember when…”
No fixed plans. Not intent upon arriving.
