> This is what's behind the paradox where a good dev working alone or maybe with one very like minded person can produce a level of productivity you can't match again as you add developers, till you have way more developers. The dip represents the loss due to having to communicate a common understanding of the codebase, that doesn't get adequately compensated for till you've added a lot more people.

Wow I couldn't agree more with this point. You put it perfectly. I worked alone and later with one other developer on a project and it felt way more productive than my current team of 5 developers!
