Conway’s Law has always fascinated me:
…organizations which design systems … are constrained to produce designs which are copies of the communication structures of these organizations.
Eric Raymond puts it this way:
If you have four groups working on a compiler, you’ll get a 4-pass compiler.
Essentially it means this: Software is a reflection of its creators.
Extending this we can begin to see how some of the natural (competitive) advantages that a piece of software may have (and the disadvantages) can be seen in the creators themselves.
It’s a powerful reminder that the team makeup matters a lot, especially in the beginning. We are all naturally biased in many ways and we bring that to the software table when we build.
