RE: Development: A Structured Problem Area?

TDD is an example of emergent behavior in the software process.  Tiny,
incremental unit tests are the 'many independent agents w/ simple rules'
clear, cohesive, loosely coupled interfaces (along with highly reliable
implementations) emerge.

Subject: RE: [pragprog] Development: A Structured Problem Area?

I am unclear about how software exhibits emergent behavior. From my
understanding of the complexity literature, emergence can occur when
many independent agents with simple rules interact; the Game of Life
being an example. I don't see software as being structured in the same
way - will you volunteer an example?
