Allen curve

In communication theory, the Allen curve is a graphical representation that reveals the exponential drop in frequency of communication between engineers as the distance between them increases. It was discovered by Massachusetts Institute of Technology Professor Thomas J. Allen in the late 1970s.

A related and highly significant finding of Allen's was his identification of the key role of information gatekeepers. Often such interlocutors were poorly recognized by management and yet conveyed vital concepts from just the right people to just the right other people in the organization.

Discovery

During the late 1970s, Allen undertook a project to determine how the distance between engineers’ offices affects the frequency of technical communication between them. The result of that research produced what is now known as the Allen Curve, revealing a strong negative correlation between physical distance and the frequency of communication between work stations. The finding also revealed the critical distance of 50 meters for weekly technical communication.

This finding was originally documented in Allen’s book, Managing the Flow of Technology.[1]

Recent development

With the fast advancement of internet and sharp drop of telecommunication cost, some wonder about the application of the Allen Curve in today's corporate environment. In his recently co-authored book, Allen examined this question and the same still holds true. He says[2]

"For example, rather than finding that the probability of telephone communication increases with distance, as face-to-face probability decays, our data show a decay in the use of all communication media with distance (following a "near-field" rise)." [p. 58]

He further explains[2]

"We do not keep separate sets of people, some of whom we communicate with by one medium and some by another. The more often we see someone face-to-face, the more likely it is that we will also telephone that person or communicate by another medium." [p. 58]

Significance

With the wide acknowledgment of importance of communication to innovation, the Allen Curve is frequently taught and cited in management literature about innovation.[3][4][5][6][7]

In the business world, this principle has had a very strong influence in many areas, such as commercial architecture designs (See for example the Decker Engineering Building in New York, the Steelcase Corporate Development Center in Michigan, the BMW Research Center in Munich, and the Volkswagen assembly and delivery center in Dresden[8]), and project management.[9][10]

gollark: Some theories have better evidence than others, they're never *definitely true*.
gollark: Well, I'm fairly sure you're wrong.
gollark: Nothing in real-world-interacting science is "proven" such that it's definitely true forever and ever.
gollark: You can prove that "in some physics model, energy is conserved"; you can't *prove* "this is the physical model the universe obeys", only show it's really really unlikely that it does anything else in the situations you test.
gollark: Yes. Our models and physical theories are derived from reality. We do not create reality with our models.
