Dunbar number for human networking is an important concept to incorporate

[kheerand]

The Dunbar number 150 (https://changingminds.org/explanations/groups/dunbars_number.htm) is an important concept that needs to be incorporated into things here.

Not sure if this should be a separate pattern or a theory that should be applied in these patterns.

Patterns I think applies to are:

• (001) Mosaic of sub-groups
• (003) Boundaries of a domain
• (006) Projects fail to move beyond early adopters
• (007) Sustaining a burgeoning community
• (008) Shared pool of knowledge
• (011) Magic of the city
• (012) Local transport areas
• (013) Identifiable neighbourhoods
• (014) Community of 7000
• (016) Density rings

Created pattern 041 Dunbar's number.

Now need to incorporate it into other patterns. Already made a reference to (001).

The Dunbar number, also known as Dunbar's number, is a theoretical cognitive limit to the number of people with whom an individual can maintain stable social relationships. It was first proposed by British anthropologist Robin Dunbar, who found a correlation between primate brain size and average social group size.

The original Dunbar number, which is often cited, is 150. This means that an individual can maintain stable social relationships with up to 150 people at any given time. Dunbar arrived at this number based on the size of the neocortex in primates and the average group sizes of various human societies throughout history.

The concept of the Dunbar number has been applied to a wide range of fields, including sociology, psychology, and business. It suggests that social networks beyond a certain size become more difficult to manage and may eventually break down, as it becomes difficult to remember names, personalities, and histories of larger groups of people.

However, it's important to note that the Dunbar number is not a hard and fast rule, and the number of social relationships an individual can maintain can vary depending on various factors such as cultural norms, personality, and communication technology. Some researchers have proposed that the Dunbar number may need to be revised in light of the increasing use of social media and other forms of digital communication, which have enabled people to maintain larger networks of weak social ties.

there have been several examples of the Dunbar number being used to inform organizational structures and team sizes.

One notable example is the company Gore-Tex, which is known for its innovative, team-based organizational structure. The company was founded by Bill Gore, who was a proponent of the Dunbar number and believed that teams should not exceed 150 people in order to maintain effective communication and collaboration.

Another example is the military organization of ancient Rome, which was divided into units of 120 soldiers called "centuries." This number was chosen because it was close to the Dunbar number and allowed for effective communication and coordination between soldiers.

In modern times, some startups and tech companies have adopted the Dunbar number as a guideline for team size. For example, the social media platform Path limited the size of friend networks to 150 in order to encourage more intimate and meaningful connections between users.

Overall, while the Dunbar number is not a strict rule for organizational planning, it can provide useful insights into how to structure teams and build effective communication and collaboration within organizations.
