Metcalfe's Law and the Church

100 Men and 4,950 Potential Connections 

 

 

As we discussed the network diagrams last Friday morning, I could not help but 

think of the value of these connections and how the concept of networking is so 

important to the ministry of this church. 

 

First, as self-confession, I am somewhat of a geek at heart.  Around 1980 I 

discovered my first personal computer and was hooked forever.  I started out 

writing software professionally, stumbled into telecommunications and have had 

a very interesting career exploring new technologies, and how technologies 

change how we work, play and become part of the global world where today 

virtually every major part of the planet is interconnected somehow. 

 

So with my geek-factor in mind, I could not help but think about the network 

diagrams Forrest presented with my geek hat on.    While these were intended to 

show the interconnectivity between people and groups within the church, they 

could easily be diagrams of any physical computer or telecommunications 

network, and I’ve probably reviewed hundreds of these over the years.   

 

Several communications principles, and the design rules and maxims borrowed 

from telecommunications can be applied to the church networks as diagrammed 

for our church and its ministry: 

 

The Hub Network Model: 

 

Where we have a limited set of 

connections and a centralized hub, 

several problems exist: 

 

1) the “networks” (ie: the 

various ministries) are limited 

in their ability to share 

information by the 

connection back to the hub.  

This hub might be a single 

person, group or even the concept of the church as a building and the 

center of our church.  In this model, if all networks wished to 

communicate, or share information or projects, the value of the network is 

limited by the few links made available for the solution and the potential for 

these links or the hub to be bottlenecks for information to easily flow back 

and forth.  Think of the hub-and-spoke model for airlines, which works 

great when O’Hare and Hartsfield have good weather, and rather poorly 

when both (and the NY corridor) are fogged in at the same time. 

 

2) The hub network also has single points of failure which can 

potentially isolate groups and / or individuals from the rest of the 

network.  In communications networks, one rarely designs a single 

connection linking networks together.  If the single connection fails, the 

network becomes an isolated island.   As I mentioned in our meeting last 

Friday, let’s take the example where one of the end points connecting 

through the hub is an individual, whose sole connection into the network 

via the hub (aka the church in this example) is the Youth Group.  If 

something happens to that person at a Youth Group meeting to upset 

them, hurt them or otherwise make them uncomfortable, the connection 

between that person and everyone else around the church (hub) is 

broken. There is just one, tenuous path connecting that person, group, 

mission team, etc to everyone else.    

 

The Church Web: 

 

Where we have many interconnections between people, groups, teams, 

FUMC, the community around FUMC, local missions, etc, etc (aka: the church web), 

several valuable concepts arise: 

 

1) The networks have 

greater value as more 

interconnections are 

made, and more people 

can connect together to 

share information, answer questions, be a resource of gifts and 

talents to others, be a prayer partner, etc.  Church becomes less of a 

“Sunday morning thing” happening at a “the hub” (aka the church 

building), and more of a network of like-minded people and resources that 

is impactful daily and weekly at work, school, life, etc.   

 

In the telecommunications industry there is a “law” called Metcalfe’s Law*

attributed to Robert Metcalfe – the guy who invented a core technology**

that allows all of our computers to interconnect / network today.   

 

Metcalfe theorized that the value of any telecommunications network is 

proportional to the square of the number of users on the network 

(Memorize that and quote in your next staff meeting – impressive eh?).    

 

In layman’s terms, Metcalfe’s Law states that a network is more valuable 

as more and more people use it and become interconnected via unique 

connections where they can share information.   

                                                 

 *Not to be confused with Moore’s Law, attributed to Gordon Moore, one of the very bright co-founders of 

Intel.  In 1965, Moore forecasted electronics would double in speed, memory capacity etc. every two years.  

So far, it’s held fairly true for every year since 1965. 

 

 **Ethernet 

 

 

As an example, if we have a simple network of two cans and a string, a 

single network connection is built between the users of the cans thus 

providing value via the one communications path between the two users.  

If we can somehow string up a tin-can-network for five people, and each 

could share information independently with each other, then 10 

independent and simultaneous connections exist between the users.  For 

twenty users, 190 unique connections could be made allowing for each 

user to have an independent communications path for the exchange of 

information simultaneously with the other nineteen users***

 

To really demonstrate Metcalfe’s law, imagine the value of the mobile / 

cellular network.  As of the end of June, 2009, over 4Billion 4 connections 

were in place around the world connecting people, machines and 

networks.  And with more and more of these able to exchange messages, 

email or access the Internet, soon almost anyone in the world could in 

theory exchange an idea, or sell a widget to almost anyone else.  The 

value of the mobile network is not based on the capitalized assets that 

make up the physical network, but the value of the sheer mass of 

humanity interconnected via a single web of connections. 

  

In our church, 100 men all interconnected via a church web represents the 

POTENTIAL for 4,950 different and simultaneous connections, 

conversations, threads of help, encouragement, etc. WOW!! 

 

2) The greater the connections, the less impact if a single link or 

connection is severed.     As mentioned previously in the hub model, if 

an individual’s only connection to the church is worship on Sunday 

morning, or youth group, or choir or local missions, and something occurs 

to damage that connection, the individual may separate from the church 

forever.  As the person, ministry, family, and / or network has more and 

more links to others within the church community, it is able to sustain 

these blows more easily, as “church” is defined by the sum of all 

connections for these entities. 

 

I don’t think Mr. Metcalfe had this in mind when he pontificated his “Law” for 

communications networks, but it certainly has merit when we look at how our 

network of ministries and people can and should be interconnected in the life of 

the church.   The greater the number of connections which exist between the 

men in the church and the church community at large, the tighter the meaning of 

“church community” as a concept.   

 

 ***for you math wizzes who are already trying to deduce the calculation, it’s ((n*(n-1))/2) where n = the 

number of people in the network that require connections).  For those who are math-challenged like me, just nod appreciably and move on

Is our church network two cans and a string?  An “Information cul-de-sac”?  A 

web of connections?  What we need and want it to be?  Is this something for this 

Allies group to tackle?  How do we get there?
