| Or this isn't about "rockstars" at all but a straightforward application of the "too many cooks" principle (and its refinements via The Mythical Man Month et alia). That is, the first project wasn't 15x as productive so much because the developers were so (intrinsically) -- or even when they were objectively all above average. But because beyond a certain optimal team size, per-developer productivity drops substantially -- even plummets precipitously (due to the factors articulated in TMM: communication, politics, etc). Plus there's a huge survivorship / selective bias example involved here (we're not look at pairings of other projects where the smaller team failed, even with better developers, because it was just too small, etc). I also suspect that if one were on the "inside" of both projects (which of course no one was) one would see a host of other factors involved (from knowledge of the requirements to market conditions, etc) not visible to an outsider. We can definitely see how anecdotes like these help promulgate the 10x myth at least. People hear about the fates of the respective teams and think "Of course, it's because those developers were individually that much more productive. I better start making my interview process 10x more difficult now ..." (BTW, no need to drill down on what I just said about the "10x myth", please. It's not that awesome developers don't exist or aren't important. It's just that for a whole lot of reasons, it is both incredibly overhyped, and objectively wrong in its fundamentals -- especially when we look at the original studies whence it supposedly derived). |
