Any piece of software reflects the organisational communication structure that produced it.

Related to product design and the observed impact of communication structures on software output.

  • a tight-knit group with coordinated behaviour creates software with entwined features and code.
  • a more relaxed, decentralised team, meanwhile, creates more modular software.

Dunbar's Number

Dunbar's number is a suggested cognitive limit to the number of people with whom one can maintain stable social relationships—relationships in which an individual knows who each person is and how each person relates to every other person.

Related to Metcalfe's and Lindy's Effect.

Metcalfe's Law

Solve the cold start problem

Miller's Number

Postel's Law

Be conservative in what you send, be liberal in what you accept

Price's Law

Price's Law states that the square root of the number of people in a domain do 50% of the work.
