Memory and Mystery

My father, Garry Berteig, recently took a trip to China to visit my brother in Beijing. Garry is an artist and an educator of great skill and insight. While there, he had the following insight:

Memory (traditional forms) is undone by Mystery (abstract forms). The next step is to combine the two into new forms in a postmodern sense… unity through diversity.

I believe this can be related to the idea of levels of mastery which I first encountered in Alistair Cockburns excellent book “Agile Software Development”. Since I don’t have the book in front of me, I have to go from memory. First there is rote learning, memorization of predefined forms. Then comes understanding of why the forms are the way they are. Finally comes the wisdom and experience to innovate on the forms.

If anyone else has any ideas about this, I would love to discuss them!

Broadcast Mode Communication

The book “The Mythical Man-Month“* discusses some of the reasons that larger teams are inefficient. The main concern is with the number of possible connections between team members. If you have two team members, there’s only one channel of communication. However, if you have n team members, then you have n(n-1)/2 channels… which grows quickly (order n^2) as n becomes larger. If one is required to work with a large team, say more than 10 to 12 people, it becomes imperative to find ways to improve communication efficiency.

One of the best ways to do this is to use broadcast mode communications. Information radiators are a simple broadcast mode tool. In a subtler way, having the team co-located** also takes advantage of broadcast mode communication: if everyone can overhear all the conversations that are going on in a room, then people can tune in when they hear something of relevance.

It is important to note that there are several other forms of broadcast communication that are useful in certain circumstances: e-mail, blogs with RSS or Atom feeds, analog radio, television (if you can think of others, please let me know in the comments). These tend to be more useful for very large communities. Radio and television have severe limits: they are not easily used in a communal fashion.

Some forms of communication may seem to be broadcast, but in fact are not. A simple web site is not because it requires that people poll it to see if it has been updated. Conference calls are marginally broadcast in that while they are occuring, everyone participating hears everyone else. However, a conference call requires active synchronized attention on the part of all the participants.

The subject of media and communication is a vast one. Some of the best writers include Marshall McLuhan and Gregory Bateson. However, there are many many more.

*Highly recommended!

**A search on dictionary.com for collocation indicates that three spellings are all correct: collocate, colocate, and co-locate, this latter spelling being the most common on the web.
